Samsung Galaxy Tab Screen Replacement Guide

Samsung Galaxy Tab 2 7″ Repair Guide:

Essential Tools:

• Safe Pry Opening Tool
• Small Phillips Screwdriver
• Small Flathead Screwdriver
• Adhesive Strips
• Heat Gun/Hair Dryer

• Prior to starting your repair you must completely power down your device.
• Next it is required that you remove your microSD card from the device.
• Using a safe open pry tool take off the back cover by releasing the clips which hold the cover in place.

After removing the back cover use the pry tool to release the battery connection located at the very bottom of the tablet.

• For the next step you will need to unscrew the Small Phillips screws (6) that hold in place the battery, which is shown to the left in the picture below. Doing so allows you to pry up and extract the battery
• Once again using your Small Phillips screwdriver, unscrew the screws (12) colored in red in the figure pictured on the right below.

• Then using your pry tool release the pop connectors which are outlined in the image below.
• Cautiously release the pop connectors and make sure not to tear any of the flex cables.
• The bottom pop connectors (2) hold in place the loud speakers. Releasing these connections will make it possible for the two loud speakers to be removed.
• After all the pop connectors (8) are released, delicately remove the motherboard from the tablet.

• (Figure 5.1) Use a Small Flathead screwdriver to take out the button flex cable located on the left side of the device, which is held in place with adhesive.
• (Figure 5.2) Remove the device’s main camera.
• (Figure 5.3 – 5.4) Remove the main spacers (2) on the top left and top right. The spacers are being held in place with clips, make sure to apply a tiny bit of pressure using the Flathead screwdriver and the spacers should pop out without much resistance.
• (Figure 5.5) Remove the device’s front camera.
• (Figure 5.6) Remove the sensor flex cables.
• (Figure 5.7) Remove the small metal cover and the rubber grommet shielding the headphone jack.
• (Figure 5.8) Remove the headphone jack/mic assembly.

• (Figure 6.1) With a heat gun (on low) or blow dryer (on medium) heat the sides and corners of the touch screen in order to loosen up the adhesive which holds the glass screen in place. Be very cautious to not overheat the screen as it’s possible to create permanent damage your LCD screen. During the removal process you may discover that you will need to re-heat some of the stubborn spots.
• (Figure 6.2) Next, wedge the pry tool between the seam of the touch screen and the device’s front housing. It can also be easier using a second pry tool from the inside of the device and applying enough leverage to begin the prying process.
• (Figure 6.3) Then continue to pry along the seams of the touch screen in order to release the adhesive holding it in place.
• (Figure 6.4) At this point the glass touch screen has nearly been completely released from all of the adhesive.
• (Figure 6.5) Eventually it should be possible to fold over the touch screen on the side of the housing where the connection is being fed through the unit’s housing. Now you should be able to totally remove the touch screen.
• (Figure 6.6) If the LCD screen is also in need of replacement simply push on the back of the LCD screen from within inner housing in order to remove it.

To fix a new touch screen you will need to clean off the dirty and old adhesive and replace with fresh adhesive strips to the device’s inner housing. This simple step will allow you to properly replace a glass digitizer.

Samsung Tab Battery Replacement Guide

A battery, after a certain period of time, will begin to lose its life span after a charging period. This guide highlights how to remove the back cover of the tablet in order to get to the battery as a means to replace it.

Step 1 — Battery 

• Make sure the device is turned off before attempting to disassemble it.
• At the top portion of the memory card slot, use the small metal spudger to create separation between the back cover and the rest of the device.
• The small metal spudger is only used to create separation between the back cover and the rest of the device, not to remove the back cover.
• If possible, try to use a normal nylon spudger to separate the back cover, as it is much softer and less likely to mar/scratch the device.

Step 2

• Use the intermediate metal spudger in place of the small metal spudger to remove the back cover. This is done by sliding the intermediate metal spudger around the perimeter of the device, beginning at the top portion of the memory card slot.
• The second picture shows the internal portion of the device once the back cover is removed.

Step 3

• Disconnect the electrical connector from the motherboard using the bent precision tweezers.
• Avoid touching the motherboard with the tweezers. Metal tools such as the tweezers can scratch the motherboard and potentially cause damage.

Step 4

• Use the flat end of the plastic spudger to pry the battery apart from the rest of the device.
• An alternative method is to loosen the battery using the plastic spudger, and then to remove the battery by pulling on the paper tab that says “Pull (Hands Only).”
• Once the back cover and battery are removed, the device should look like as illustrated in the second picture.

Do Christmas Lights Need to Be PAT Tested?

Is your office lacking the festive sparkle that comes from Christmas lights because you’re scared they’re not totally safe? We’ve got good news…(and yes we realise it is way too early to mention that dreaded word!)

Christmas lights are one of those objects we all wheel out that time of year. By the time the festive season arrives, they’ve probably been living in a cupboard for the past eleven months, or lounging in a loft somewhere, gradually tangling themselves together into totally unreasonable knots.

Once you’ve got them out though (and forced an employee to untangle them, potentially leading to things being thrown – dodge that pot plant!), a lot of firms either don’t put their lights up at all, or end up spending money getting their lights PAT tested every year to make sure they’re safe.

Now we’ve said it before and we’ll say it again – PAT testing is NOT a legal requirement every year. It is only a legal requirement annually in high-risk environments where equipment may be subjected to extreme stress. Examples of this include construction sites, but it’s pretty unlikely you’ll be putting up your Christmas lights in one of those.

With this new information in mind, we can tell you right now that Christmas lights don’t have to be PAT tested. Instead, it is more than acceptable to conduct a simple visual check on all of the cables and lights. If any are damaged, wiring is frayed or other factors are in play, you should replace your lights.

In other words, use your common sense, and if something looks dangerous, don’t use it!

Now go and check over your lights and get them up. Christmas demands it.

PAT Testing for Mobile Businesses

PAT Testing isn’t just for businesses and large companies.

 

Portable Appliance Testing isn’t just for businesses and large companies; in addition it is a fundamental requirement of most insurance policies where the public could be put at risk.  So whether you are a mobile hairdresser, gardener, locksmith, handyman, DJ or self-employed builder you need to comply with the regulations.

The Health & Safety Executive states that 25% of all reportable electrical accidents involve portable appliances.

PAT Testing is the common terminology.  The correct term is “inspection and testing of in-service electrical equipment” – so in fact it’s not just portable equipment any more but any electrical equipment.

The level of inspection and testing required is dependent upon the risk of the appliance becoming faulty, which in turn is dependent upon;

1. The type of appliance,
2. The nature of its use
3. The environment in which it is used.

For example a mobile hairdresser could use many electrical items hairdryers, curling tongs, hair straighteners and shavers to name but a few and it would be advisable for them to check what their insurance requirements are for PAT testing.

Incidentally mobile hairdressers are not classed as ‘low risk’ like an office, they are high risk as their equipment has the potential to become dangerous as it can easily get wet and easily get damaged.

All electrical items have the ability to short fuse, overheat and in the worst case scenario, spark or cause a fire.  The last thing any independent hairdresser or indeed any other trader who offers services in people’s homes wants is to go to a client’s home and find themselves in a situation where they could potentially be causing harm; not just to a person, but also their home.

Ensuring each item is regularly PAT tested and keeping a log of this makes for good business practice.  The benefits far outweigh the cost.

Covert Cameras in the Care Sector

Examples of covert cameras in care

In recent years, there have been an increasing number of cases in which secret filming has been used to expose the abuse of vulnerable patients in care homes. In one high profile case in October 2012, six care home staff members were jailed and five were given suspended sentences after several incidents of shocking treatment of disabled patients at Winterbourne View care home were secretly filmed.

The footage, recorded by BBC reporter Joe Casey, who posed as a care worker, was broadcast on television in a Panorama programme in 2011. It showed both physical and psychological abuse suffered by patients at the hospital, some of who had conditions such as autism and learning disabilities.

In other cases widely reported by the media, incidents of abuse were filmed by secret cameras placed by family members.

In one such example, a camera was set up at the Granary care home at Wraxall in 2012, by the son of Gladys Wright, a patient who suffered Alzheimer’s disease. The footage showed staff swearing at and shoving the 79 year-old, with the result that three workers pleaded guilty to ill treatment and were banned for life from working with vulnerable adults. One of the three workers admitted stealing the dementia patient’s food and was jailed for four months, the second was given a suspended jail sentence and the third a community order to do 180 hours of unpaid work.

Subsequently, in March 2015, Shaw Healthcare, which runs the Granary, reportedly told the BBC that it had instructed staff to confiscate any hidden cameras they may find in future, citing “legal issues around filming people without their consent and the ability of those who may not have the mental capacity to give proper permission”.

Satelite Repair: Duotech Advise

Solving and Fixing Problems with a Satellite Receiver

If a satellite receiver is not working properly, it may be caused by certain connections or settings. Here are some common problems with receivers that are solvable within a few minutes.

Snowy Screen

A snowy screen often occurs when signals from the satellite aren’t being received by the television. A common cause for this problem can be improper connections from the receiver to the components. Check to be sure that the television, DVD/DVR, and sound system are all turned on. Examine the back of the receiver and the other components that are supposed to be connected to it. Make sure there are cables going from the receiver to all of the components. If there is a missing or loose connection, this may be the reason why there is no picture.

Improper settings of the receiver’s components can also be the cause of this problem. For instance, the television should be set on a certain channel to deliver satellite signals. Channels can easily be moved by a slip of the remote, and the satellite signal cannot get through when the television is on the wrong channel. Additionally, many televisions have input modes that must be changed in order to get the correct information to the component that is in use. Consult the television’s manual to see where it should be set to receive certain audio or video information.

No Digital Sound

This is commonly caused by the settings on the receiver. Check to see if the receiver has been set to receive digital sound. It would also be a good idea to check the connection between the sound system and the receiver. Check the owner’s manual of the system to make sure everything is connected properly. If this doesn’t solve the issue, it could be a problem with the sound system itself.

Receiver Is Turning Off or Changing Channels by Itself

Don’t automatically assume the receiver is bad if it is changing the channels or shutting off automatically. If the receiver uses a UHF remote, a neighbor may be using the same type of remote for their satellite system, and signals from their remote could be traveling through both homes. If this is the case, the receiver’s manual should outline how to change the address code on the receiver to prevent it from happening again. It is also a good idea to check to see if other remotes inside the home could be the source of the problem. If the receiver does not have a UHF remote system, try resetting it.

Signal Loss

If there is a message on the screen that indicates a loss of signal, it means that the receiver isn’t getting any information from the satellite. The problem could be attributable to the connection from the satellite and the receiver. Check the connection between the two. Try unplugging the cable that runs from the wall to the receiver and reconnecting it. If this doesn’t solve the issue, there could be a problem with the satellite provider.

Conclusion

Before pronouncing a satellite receiver dead, troubleshooting it would be wise. Connections from the receiver to the television, DVD, or speakers can become dislodged or loose, and remotes can also be the source of receiver problems because it is easy to inadvertently change settings and channels. Consumers can save a lot of time and worry by checking for these small problems and mishaps to get their satellite receivers working again. However, despite concerted efforts to troubleshoot a receiver, it may have seen its better days and will need to be replaced.

Part-2 Faulty goods? You’ve still got rights when the guarantee runs out

 

The steps you can take

1. Contact the retailer’s head office: You won’t get any joy from youthful shop staff or call centres. Be firm and explain you think your product hasn’t lasted a reasonable amount time. You want it to be investigated and repaired, or replaced if it turns out to be faulty.
2. Get an independent report: A major retailer is likely to have its own repairs centre or an arrangement with the manufacturer, but this may result in sky-high call out charges. Contact an independent repairer (DUOTECH ELECTRONICS) and ask it to produce a report. Most of the independents we contacted charged between £30 and £40 to visit and many would write a short report as part of the cost. You can claim back up to £200 for the costs of the repairer’s bill.
3. Commission a repair: Ask the retailer to repair or replace the goods. If the repair cost is disproportionate the retailer can offer a refund of the original purchase price, though probably not a full refund. If the shop makes life difficult you can ask go to an independent repairer and reclaim the whole cost. Make sure they provide evidence of the fault.
4. Be prepared to battle: The company could refuse to refund the repair cost, leaving you to chase them through the small claims court. A judge can order the retailer to settle the claim – up to £5,000 – and pay legal costs. For information on taking a case to the small claims court, read our guide published last week (theguardian.com/money). Consumer Direct is the government’s new online and telephone advice line. Call an adviser on 08454 04 05 06.

The Department of Trade & Industry says the rules are clear and as long as you have evidence of a fault the judge will be sympathetic. But David Oughton, professor of consumer law at De Montfort University in Leicester, says an EU Directive has muddied the waters. “The presumption underlying the new rules is that you have two years to make a case.” He says judges may override the old rules giving protection up to six years.

A spokeswoman for the DTI says: “There is a common misunderstanding that the EU Directive requires a two-year guarantee to be given, but that is not the case. UK law in practice provides better protection for consumers than the two-year minimum required by the EU – consumers are able to pursue relevant claims for up to six years (five in Scotland).”

Part-1 Warranty claim EU Directive: Diagnostic report by Duotech Electronics

A little-known EU directive is making shoppers feel like they have extra ammunition to return faulty goods for up to two years. It’s not quite that simple. Read our guide to see if it can help you.

There has been an increase in people using a little-known European Union directive to get retailers to refund or replace faulty goods, even after the stated guarantee periods have ended.

The EU rule allowing the return of goods up to two years after purchase is at odds with the returns policies adopted by most major shops.

However, as this is a directive is only partially adopted by the UK, its use is a grey area.

Despite this, many shops have willingly refunded items when presented with the directive and its argument, so it could potentially improve your position.

So what has happened?

Most major retailers will have a stated returns policy that complies with UK consumer law. Those interested can see the exact wording of the Sale of Goods act here, but put simply the law says that retailers must sell goods that are ‘as described, fit for purpose and of satisfactory quality’.

If a defect is detected when, or in a reasonable period of time after, the sale is made, then buyers can demand a full refund.

However, the rules get fuzzier when faults develop over time and a buyer has to return goods after possessing them for a longer period.

Under UK law, buyers in England and Wales can get a partial refund or full repair up to six years after the purchase was made (five years from discovery in Scotland). The refund should take into account how much use the customer has already had of a product. Ultimately, a county court would decide this.

However, the likelihood of getting such a refund is dramatically reduced after just six months. The reason is that for six months after the purchase, it is up to the retailer to show that a fault on an item is down to the actions or misuse of the buyer, rather than an inherent fault in the product.

After six months, the burden of proof switches to the buyer and it is they who must then show a fault is due to some inherent problem, something that can be almost impossible in all but the most straightforward cases.

Sounds complicated?

For example, the plasma TV you bought five months ago stops working without explanation and you return to the shop you bought it from, expecting a refund. The store manager is reluctant but can find no explanation for the fault. There are no scratches or damage to show it has been dropped, or signs of water damage. Complying with the Sales of Goods Act, he understands without such proof he must refund you money.

But were the fault to develop at seven months, he would not need such proof. The TV may show no signs of damage or misuse, but the store manager no longer needs to show there was any. Instead, you must show to him that there was a shoddy component or design fault that caused the problem. In the absence of these things, he is under no obligation to return your money.

In reality, most retailers offer returns policies that extend this 6-month period to 12 months. But after that refunds are hard to come by.

An examination of your faulty item in conjunction with a diagnostic report this will help you prove your item as a premature manufacture defect.

Cost of diagnostic report for electrical items vary from £25 to £50 dependent of type of equipment
