Sony Vaio is one of the most prominent brands of laptops on the market, and also one of the most expensive. The laptops, created by Sony, are known for their efficient processor functionality and sleek designs. While the Sony Vaio line of laptops are considered high-end, they are also prone to display problems.

Symptoms
Among the problems facing Sony Vaio laptop screens are blackouts. When these blackouts occur, the monitor turns solid black, and upon rebooting the laptop, light will briefly flash on only to blackout again. Additionally, there have been reports of an issue which causes the screen to flicker intermittently until it goes out all together. b> Troubleshooting b> Blackout displays and the continuous flickering of Sony Vaio screens can be caused by various issues taking place inside the laptop. It is not necessarily true that the problem lies within the LCD screen itself, with display issues often occurring as a result of problems with other parts of the laptop. You can test whether or not the screen is defective by connecting the laptop to an external monitor. If the display comes up normally, then the problem lies within the laptop's LCD screen. b> Parts b> If your Sony Vaio is connected to an external monitor and suddenly goes black, then the problem may have to do with the laptop's sleep button. The sleep button latch located inside the device may be jammed or broken, thus putting the screen in a permanent sleep mode until the latch is fixed. Encountering hissing sounds when the laptop is running indicates a faulty circuit board, usually damaged due to overheating. Display issues can also occur when certain parts of the laptop, such as the hard drive, have been replaced. b> Design b> Some owners have made complaints about Sony Vaio design flaws, specifically mentioning defects in the laptop's boards. Among the problems discovered after opening the laptop include burnt LCD fuses, as well as worn out circuits and internal latches. Some of these events may occur even in newly purchased units. Sony has not yet responded to various consumer complaints and has not yet issued any recalls in response to reported problems. b> Repair b> When repairing a defective Sony Vaio laptop screen, it is important that owners remain aware of the nine screws which hold the laptop cover and the board together. Not doing so can easily lead to further damage to the Vaio due to static electricity, and may even lead to a short circuit. For owners who are experienced in the area of laptop repair, parts are readily available for purchase, allowing for cost efficient repair. b> Extended desktop You will need to connect to another monitor or your television to your computer with the vga lead monitor connection.

its most likely the pixcles have all when out in the screen

if you want i can give you service manual

you will need the restore cdrom's to fix this issue. sounds like you the wrong upates! you should only updates that come from the sony web site for your particular sony item.
refer to sony tech support.

Sounds like the inverter went bad. Can be replaced, but if an older Vaio, it may not be worth the cost.

sounds like the backlite for your monitor needs to be replaced. (like the lightbulb went bad) These can be replaced usually, for under 100 dollars.

when u power up press F8 key then enter in enable vga mode then change screen resolution to 1024*768 then apply and ok thats it.

Try turning it on without the battery.

when windows is loading try pressing F2 or F8 or F10 I don't remember off the top of my head which one will do it. But try to get to the system restore. (F2 i want to say) this will reinstall windows without erasing all your files.
