    I had the same problem. I cleand the power supply and the inside of the computer with compressed air. I put things back together and everything worked for a day and then same problem started again. the system comes on, but the screen is balck. Sometimes if I push the ON/OFF button the yellow light comes on and if I push it agian I see the screen for a few seconds and the it goes dark.

    I think it may be related to the system getting hot, but fans are working

Actually its not any of the above solutions. The W20 is Sonys all in one unit answer to apples iMac. I have a PCV-W20 and the computer will boot up show the windows logo for a split second and the backlight goes out, if you hit del and f4 to go into the bios it will get to the bios screen for a fraction of a second and turn off aswell. I pulled the backpanel apart and reset the cmos, nothing changed so I thought it was a bad backlight and replaced it. Actually its the video inverter board that is bad. Its a known issue with these because they run hot, however the part to replace it from sony is $375.... I have been looking on ebay and around for a 3rd party part but havnt been able to find one for the last 6 months.

This could be the bios looking for the boot.ini file or a faulty driver, try pressing F8 on boot up and when prompted with an options screen, select 'Last Known Good Configuration. and press enter. The pc should restart and boot into windows. If no boot then try, if you can using your monitor on a friends pc to check if the monitor is faulty or the software.

My Sony Vaio PCV J100 turns on but no nothing comes on the screen/monitor. I have checked the monitor but it works fine on other computers. What could be the problem?


If your monitor works fine on another computer then most possibly its your video card since you said nothing comes on. Usually if its the operating system you should see the computer info before it goes to a blank screen. If you have an add on video card try using the integrated video card or vise versa. You can also use a known good video card from another computer.

My pcv-w20 has been sitting over a year, the lcd monitor show's the desktop and operates normal except that theres no light to the screen (had to use a flashlight to see it) just went dark one day! ...


There is a $20 part called the "inverter" that has failed.
Add $50 to $75 for a qualified video/TV technician to disassemble the LCD, replace the part, reassemble, and test it.

Noisy fan when downloading larger files


Well this really isn't much of a problem, as the fan turning on shows that it is doing its job. It turns on due to processor having to run faster, naturally raising its temperature, so the fan keeps the processors temperature within operable limits.

Display shows SONY sign and goes black


Are the fans still runnng when the screen blank out? If not so the power supply is dying most likely. Did you add more devices, and wattage might be enough, when did it start happening? Can you trace back when it started and any changes you have made. It might be a problem in the monitor part of it. Marcel
