Question about Toshiba Satellite P25-S507 Notebook

1 Answer

Toshiba Satellite blank screen

Internal monitor screen is blank.It was left on overnight, in the morning wouldn't come on.The hardware power management software (Toshiba's) is set to turn off the monitor after 30 minutes of inactivity.On top of that the OS's screen saver is set to blank after 60 minutes.When the touchpad/keys was tapped the monitor turned on but stayed blank as if the blank screen saver was on - a faint glow of the blank screen (visible in darkness) was the indicator.After the laptop was turned off and on , the same faint glowing blank screen comes on, nothing else , not even BIOS booting info.No visible output whatsoever.A DVD inserted played normal except no visible output - screen blank, sound played only.I got a tip that the computer is stuck in a twilight-like state between hybernation and some other state and to remove the battery for a complete power-off cycle - did that and it didn't help.I suspect either a hardware failure or hopefully just software.No external monitor is available for further testing.OS: XP Home Edition service pack 2.Laptop: Toshiba Satellite P25-s507 ( PSP20U-OOVY3V)

    UPDATE: external monitor works, so it's not the video card.Based on my research of similar problems
    posted on the net it's the inverter.The internal monitor flickers faint glow on and off when the monitor's 'close' miniature button is pushed .Please advice somebody, it's been many days and not one answer :(.

Blank Screen

The bad thing about this is that it could be a software related issue or a hardware issue. If you're willing, you can disassemble the unit and check for a damaged or loose connector to the monitor. If there doesn't appear to be any issues there it may well be that the screen has gone bad or there is something wrong with the driver/setting on the unit itself that is causing the screen to saty off. I'd move forward with the hardware issue first though.

Toshiba satellite p25-s509

I think this is already a hardware problem, it could be your LCD or your systemboard, try connecting an external LCD or monitor thru the VGA -out & check if you have a display. If not, it might be your systemboard that's causing the problem & this may require service.

Hope this helps.
