SONY REPAIR FAQ:
Sony
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W Motherboard
The computer won't switch on or will crash
intermittently. Some video problems also require a motherboard repair
as most video chips are soldered onto the system board. Our engineers
perform component level repairs on most Sony motherboards. We can
replace resistors, capacitors, transistors and also work on the major
chips within your system. Our engineers have many years of experience
and know how to fix most systemboard faults.
Sony
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W VGA Video Graphics
faults
The system starts up with dots or lines on the
bios or intro screen. Graphics are distorted, blocked or pixilated.
In some cases the system refuses to boot. Strange effects when
windows or mouse are moved on the screen. All these effects can be
caused by a faults related to the graphics chips. About 90% of
faults can be repaired, the rest are caused by cracks on the
motherboard and impossible to repair. Our Advanced Video Repair
Technology enables us to restore full function to your laptop in
most cases. Manufacturers and their tech support always recommend
that you spend hundreds on a new motherboards - we've got a cheaper
alternative. Examples: VGA

Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W
Power Jack Pin or Socket
The laptop will not charge the battery. When
the battery power runs out the computer stops working. We repair or
replace power sockets where the power pin has broken or has become
disconnected from the motherboard. In some cases the power connector
makes a poor connection with the Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W jack. This causes arcing
which can generate enough heat to melt the Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W dc jack and the
power pin may become lose. It is best to get the power socket fixed
before the battery is totally depleted as this can cause permanent
damage to the battery.

Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W
LCD Backlight & inverters
The laptop switches on but the screen
remains dark. In some cases a faint image is visible on the Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W
screen. This problem can be caused by a faulty Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W fluorescent light,
inverter, video cable or a problem on the motherboard. Specialist
tools are required to determine the exact cause of the fault.
Backlights use very high voltages and it is easy to cause damage to
the system if they are not correctly handled and installed. Our
engineers can replace the backlight lamps in most TFT/LCD screens
including the new xbrite panels. We also have access to most backlight
inverters and cables. We can perform repairs on some very rare
inverters. It is very easy to destroy an expensive LCD/TFT when
removing/installing the CCFL. Our engineers are trained using broken
LCD panels before they can work on a customer's LCD/TFT unit.
Sony
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W LCD Screen
We can supply original Sony and compatible
replacement LCD screens. In some cases only refurbished screens are
available. We don't charge extra for installing and testing screens.
Screens come in various sizes (measured diagonally in inches) and
resolutions(XGA, SXGA, SXGA+, UXGA...) We need the correct size and
resolution to provide you with an accurate quote. While-U-Wait

Sony
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W Keyboard
Most Sony keyboards are damaged by liquid
spills and general wear. We can supply or install keyboards for most
Sony laptops. We also repair keyboard connectors on the system
board.
Sony
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W CPU problems
Intel CPUs hardly ever go wrong, but are
very difficult to diagnose. Some will crash on rarely used
instructions and at certain temperatures. Unfortunately, hours of
testing can be in vain if the problem instruction isn't executed.
Overclocking a Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W CPU in a laptop is not recommended as the
cooling systems are designed to dissipate heat at normal speed.

Overheating
We can install replacement Sony fans and
heat sink parts. In cases where the original fan is not available, we
can install substitute fans which will be equivalent or surpass the
performance of the original Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W fan.
Sony
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W Hinge
Some laptops have a problem with the hinge
becoming stiff. It becomes difficult to open and close the laptop lid.
The plastics may also be damaged by a defective hinge.
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W CD/DVD and floppy drives
Our engineers can repair or replace these
drives. We have a lot of drives in stock and the work can be carried
out very quickly.
Sony
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W
Hard Drive
Faulty hard drives can cause data loss and
stop your laptop from booting into Windows. We can replace faulty hard
drive and attempt to recover your data. After installing the new
drive, our engineers perform a thorough disk test to ensure that your
data is as secure as possible.
Sony
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W Software and Drivers
Viruses and improper shutdowns can lead to
the Windows XP operating system or the file system becoming corrupted.
We can recover your data and install a fresh operating system or
drivers to prevent crashes. We can also recover your data from totally
dead or unusable computers.
Sony
Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W Charging problem
Charging problems can be due to
batteries nearing their end of life, power supply problems or failed
components on the motherboard (FET, MOSFET, Transistor, Diode or
Capacitor).
Secondhand
or Used SONY Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W
Buying a used laptop is a risk. You may find that the battery
does not accept a full charge or the laptop is unstable. Most
secondhand sellers consider any laptop that boots into Windows as a
working machine, even if it keeps crashing every five minutes. We
strongly advise customers against buying used laptops with a
DOA warranty as some faults are not immediately apparent.
BIOS
update SONY Vaio VGN-N21Z/W VGN-N21ZR/W VGN-N29VN/B VGN-N31L/W
Many motherboards are destroyed by incomplete or corrupted BIOS
updates. A BIOS update should only be performed if it is critically
important. Don't do a BIOS update just for the sake of having the latest
version on your computer. Ensure that your computer is stable before
performing a BIOS update. Run diagnostics to check memory, hard
drive, keyboard and video graphics. In
99% of cases a failed bios update will make the computer totally unusable
so take a backup of your software and data too. Make sure that you
have a good connection to your mains adapter and that the battery is
fully charged. NEVER, NEVER, NEVER interrupt a BIOS update. Let it
finish, even if it seems stuck and takes a long time.
