When I turn on the computer the screen comes up, shows windows booting and then after a minute the screen backlight goes off. The desktop is still there but only in bright room lighting. You can see almost a ghost of the desktop and if you can see the cursor, you can navigate somewhat. Pushing the function key and then F5 will bring the screen back on for a second or two but that is it. Sometimes the sreen backlight will not come on at all.

Re: travelmate 2400 monitor turns off
First try going into the display properties, in the screen saver tab you will see a button marked power, click on this and set the screen to never. This will set the screen to stay on, however, this is most likely a problem with the screen inverter or the screen itself. Check the screen connections, they sometimes work loose. At this point all that's left is the screen and inverter.

You first need to check the screen is working, disconnect the VGA/DVI cable from the monitor, then turn it on do you get anything on screen at all?
If that works reconnect the cable and turn it on, now boot the PC, do you see anything at all on the monitor?
No then check the cable/swop with new one or check the graphics card.
Yes but goes off after a few seconds, reboot and press the F8 key as soon as you hear the first beep, this should bring up a start menu, try safe mode, if that works load and windows it might be the graphics driver (has this been updated?) if yes try roll back to previous driver or you could even try system restore back to a date you know it all worked.
Please verify the power option setting present in 'control pannel' option once. If you have selected to turn off the power supply after 10mins, (once the system is in idle state) then the SMPS will stop supplying power.
try to turn off you screen saver just turn off power monitor to see monitor easy wake up after long time.if ok means windows screen saver have problem if still same look like is you monitor something wrong need to check
It's turns blue to power safe mode (yellow) it's prevent futher damaged to your monitor. It's seems you got a busted backlight inverter. Need to replaced a new one...Since you only got it for a few months, send it back to Acer for a replacement of a new backlight inverter... Have a nice day!
This doesn't necessarily rule out the inverter. I've had inverters with intermittent problems that had the same effect, so having the inverter tested is the only way to rule it out. Other possibilities are a bad connection, a corroded/dirty pin or socket in a connector, a bad ribbon/cable, and a failing backlight. If it is a failing backlight, the entire screen will need replaced, as the screen is considered a sealed unit and the backlight isn't available and not considered a replaceable item. Also, it's rare, but it could have a faulty motherboard component or video card. I'm leaning towards a faulty backlight, but keep in mind the inverter and cable possibility. Start by checking and cleaning all connections.
It could also be that the video card is not compatible with this monitor. After the pc boots up, can you get into windows? Does the monitor always go out at a specific time on boot? Say for example; you boot the pc, windows startup splash screen comes on; screen does a quick flash and goes blank. Then it maybe the BIOS setting for the video. Try changing the IRQ setting. You could also try putting the video card in another slot. Do you have the manual for the motherboard?
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.
