No image on laptop screen graphics fault

Has your laptop been overheating lately? This common problem can often break your graphics card. Here at Ninatec we can repair this problem for you.

Look at the images below. As the tiny balls on the underside of the graphics card are broken our skilled engineers fix this issue using the latest BGA reflow machines from Hong Kong.  First we flow flux under the chip at 140 degrees then we fire infra red light at the chip.

This makes the solder balls underneath the chip melt and this removes the bad contact from the graphics and the image will be displayed on the screen again.

 

Have a look at the video below here at ninatec this is how we reflow the graphics card.

Some companies reflow the graphics chip but do not fix the fan. The fan is what caused the problems in the first place. The fan usually gets clogged up with dust and over heats.

laptop-overheating-fan

The fan must be repaired. It needs to be taken to bits, oiled and put back together with CPC paste applied to the graphics card and the processor to cool it down.

This fan is in pretty good condition most of the fans we receive at our workshop are in a terrible state. So if you fix the graphics card but do not fix the fan, the problem will return.

Ipad Motherboard Repair Specialists

t 0800 118 2275    Engineer direct – 07519775532

The motherboard inside your ipad is a printed circuit board. On the motherboard are mostly capacitors resistors and diodes integrated circuits and power manager chips. These chips help in moving the current around the board and control how the operating system uses your hardware. We have been repairing laptops longer than any other company in London and the UK. In the image below we have enlarged a PCB for you to understand how we work.

Over heating fan problems on Laptops

Overheating often occurs on a laptop. Your laptop acts like a Hoover it sucks in cool air from outside the laptop and blows out hot air from the processor area.  However after a year or two the grills get completely blocked, you may get worried about the heat and sp you should be ! The laptop cannot breathe the processor gets extremely hot and cannot be cooled down. Underneath the processor is a heat sensor that makes the fan spin and also shuts the laptop off when the heat reaches a critical level. This laptops fan was not spinning at all that’s because there were large clumps of dust inside the fan area blocking the fan from spinning. This caused the laptop to switch off every hour or so.

The laptop would switch off right in the middle of the customers work. This caused data to be lost. Important windows files where lost. After repairing the fan and replacing the fan, the laptop had to have the files saved from the hard disk and windows reloaded as the shutting of had corrupted the operating system.

overheating-switches-offCan you see how a hardware problem caused a software problem?

laptop-switches-off

This is a common cause of a laptop failing to boot up and turn on. . The processor has paste on top of it called heat sink coolant paste after a year or so the paste hardens and needs to be replaced. There are integrated circuit chips around the processor that may fail or Bobinas that may fail and in many cases capacitors short out.

Sometimes The power pin is not connected properly to the motherboard one or two of the legs may have bad contact in this case the pin needs to be resoldered to the board.

Ipad board repairs

Sometimes integrated circuit chips are blown on the motherboard. In this case the exact chip that you remove from the motherboard has to be replaced. Once this is done professionally and CAREFULLY the laptop will turn on and boot up. These are the most common causes of a laptop not turning on. There are a few other reasons but give us a call for free advice to get to the root of why your laptop is not turning on.

How to solder like a Boss

Soldering has a lot to do with experience as it is in knowing how to solder. For example over the years I have taught many newcomers to electronics how to solder. I can show them how to solder, where to put the soldering iron and how to use the flux and so on. The problem is that many newcomers have shaky hands, or they may leave the soldering iron to long on the motherboard or maybe not long enough. This is where experience comes in. Our engineers were taught by the military.
We use soldering techniques that are unheard of to many soldering techies. Here at Ninatec we use stereo microscopes with micro tip soldering irons enabling our engineers to solder micro components on the main board. For example look at the image below.

 

All images are copyright of Ninatec Laptop Repairs

 

 

 

The image above was taken through a Stereo microscope. The soldering looks great. You can see the positive pin to the right on its own sector of the motherboard. All the pins to the left are negative. The engineer who has many years of experience will solder a new pin to the motherboard, when finished the board will have no excess flux residues. Some newbies who have never soldered on mainboards will create a lot of problems and could even blow the main board if he is not careful.

What you can see above is a repair carried out by a novice technician.  Yes the pin on the left is a repair !! The power pin had broken on the customers motherboard and a ” laptop repair shop” had repaired it. The solder had broken off the pin and onto the motherboard the customers laptop would not turn on.  We removed this pin from the motherboard and replaced it with a new one to the right.

Here is the finished result.

A perfect repair.

Soldering requires years of experience.  You need to use the correct flux, the correct solder, and you need to understand heat exchanges on the board including how long a component can with stand heat. An engineer understands that he needs to get in real close. Powerful microscopes and microtip tools help our engineers get much closer to the subject enabling them to make a better repair.

 We charged the customer £60.00for this repair and everyone was happy.

Projector not turning on

When a projector fails to turn on in most cases this is a power supply problem. Here in the 2 images below we have opened an optoma projector and are repairing the board. As you can see from the first image there are 2 16volt capacitors that are swollen. This is usually a sign that they are dead. So we remove the capacitors and this usually fixes the problem with the projector not turning on.   bad-capacitors                         .

 

 

 

 

 

Look at the image below.

good-projector-lights

 

As you can see we have replaced the capacitors on the power supply. The capacitors now have nice flat heads. failed capacitors cause a projector not to start up. This can sometimes occur on Toshiba projectors.

This is not always the case as sometimes the motherboard for the projector will need replacing.

So if your projector is not booting up or not starting give us a call today.   0800 118 2275

LAPTOP MOTHERBOARD REPAIRS LONDON

Sometimes we get laptops into our office that do not turn on. One day we had a Sony laptop that did not turn on. The repair was quite difficult but we got there in the end. When we opened the laptop and removed the motherboard we noticed there was liquid damage on the motherboard. laptop motherboard repairs

Chip Removal

This customer spilt liquid on the laptop and did nothing about it for a month. One day she tried to turn it on and it did not turn on. Sometimes it did turn on but then would switch itself off.

We removed the motherboard and straight away we could see the liquid damage. The damage was all around a large power manager chipset. So we removed the 100 legged chipset for examination. We cleaned up the whole area.

We could see the damage had eaten into the motherboard. The way to remove a chip like this is to clean the board and then put some heat resistant tape on the motherboard to protect it from the intense heat of a hot gun. So We removed the chip using special flux and a hot gun.

After removing the 100 legged chip we could see the problems. motherboard repairs london

Legs Missing

The motherboard had lost its copper footings. We soldered new solder onto the board so the chip would fit back nice to the board again when ready for refitting.

In the picture to your left you can see that leg number 6 is missing on the chip. We have placed the chip upside down as it was easier to clean.

How do you create a leg that has disintegrated?

We took some solder braid. This is copper wire that is thinner than a human hair. So our engineer took a strand of this coper wire and soldered a tiny strip around 2mm long straight onto the motherboard.

 

Creating legs

IMG_20150208_210836

 

The motherboard at this point leeds to be perfectly clean. So again the board was cleaned and the copper leg was soldered in place.  We soldered The leg into place. You can see this on the image number 3 on the left.

You can see the small wiring buried inside the motherboard. You can also see the leg we have created. We made it a little longer than needed as this leg needed to be bent up and connected to the chipset when we soldered it back into place.

Leg number 2 was also missing on the motherboard so we just added some solder into its place so the chip would stick to it again. The second leg looks a bit crazy but as long as the solder at pin 2 does not touch pin 1 everything will be fine.

DSC_0090

Our engineer re soldered the chip back onto the motherboard. You can see where the copper wire that we placed underneath the chip now needs to be attached back onto the chip. To do this kind of work you need to be like a micro surgeon.

You need a stereo microscope. You also need great tools including a micro soldering iron. If you do not have these tools this type of work should never be attempted. While soldering the chip back into place a small orange capacitor broke off the board and was put back on again.

The big question is after spending all that time on this laptop would it boot up and work again?

Our engineers Have been repairing laptops for almost 20 years now. We know its going to work when we spend all this time on the laptop because we really do understand how motherboards work. The laptop was put back together and bingo !!

Another laptop fixed. 

Our engineer spent 4 hours on this laptop and we charged the customer £75 for the repair.
