Re: Toshiba Blank Screen Help
Sounds like dead cells or dead circuitry in the battery, If the cells or circuitry in the battery are shorting across in the battery than all the voltage is being robbed to "charge it". Hopefully the voltage regulating chips on the board are not corrupt as this will cause the system to short everytime a battery is put in.

Hi...I have had the same problem with my A210 laptop as well over the last year.The problem is sporadic and it would just happen out of the blue.My daughter has the same laptop and the same problem.The screen would go blank ,but you could tell the computer was still functioning somewhat in the background.The only way to fix it was to reboot and if you were working on anything it was lost.I also recently had another similar problem.I had the laptop set to go to sleep when i shut the lid.This worked great for a year or so.When i opened the lid the screen would come back on and i could continue using the computer where i left off.But recently when i opened the lid the screen would come back on for a few seconds then go blank ,just like it did as described in the first problem above.Not sure why as i had not changed any settings on my computer.It happened every time i closed the lid then opened it.A pain as had to reboot to get it back.Here is the fix my friend discovered.Click on the ATI icon in the taskbar and open up the CATALYST CONTROL CENTER.Make sure the advanced view is selected.Now choose "display options".Put a dot in "Detect whenever catalyst control center is opened",and leave the other 2 spots unchecked.( I had a dot in these 2 places ). Now apply the changes and close it out. I have had no problems since doing this with the screen going blank.Not sure why this worked ,other then the computer was getting confused along the way and shut off the screen.Just be aware that if you hook your laptop to a TV you will have to revisit the ATI setting and change them back.....Hope this helps...Dan
Take a bright light and shine it on the screen when it is on. Can you barely see any display, but really dark? If so, the lamp or the lamp inverter has failed (some laptops use LEDs instead of CCFL lamps and has no inverter either).
Just hooking up to another display doesn't necessary tell you anything if it doesn't show anything. As sometimes you have to change a settings in the BIOS, use the Fn key plus another key that looks like a monitor, or change it through a display menu on the screen.
