Laptop LCD wont power on. Wierd intermittent problem.

[azmodien]

I have a Toshiba 1110 Satellite and for some reason, the lcd backlight wont power on. When I start it up, I get the "Toshiba" splash screen and then the backlight shuts off. I can just barely see the windows desktop.

Heres the strange part, I plugged in an external monitor and then restarted, causing the lcd to light up perfectly. The screen will then stay on until the next time the monitor is shut off, then it's back to not working.

I already had the inverter replaced and that did not help and then the repair shop wanted 700 bucks for a new screen ( how those idiots figure that $700 is an economical quote for a 3 yr. old computer, I do not know )

Anyway, it seems that the screen works perfectly fine until I shut the it off. So I am kind of baffled as to why it wont power on unless I plug in an external monitor (????????). Any suggestions would be very much appreciated.

Thanks.

Just a side note: if I have to replace the screen, am I able to use any compatible 14.1" TFT? Because I heard that the compaq presario 1700 uses the same screen and there are quite a few on ebay for next to nothing.

First I would try to set everything in BIOS to "safe" (or whatever they call it). If no help, I would contact service at Toshiba. This may be a known problem to them.

update: notebook will no longer power on AT ALL. Green lights flicker for a second and the go out, even with the AC cable plugged in. I guess its not the screen after all.

Sounds like a bad power plug. Id try another one and see if it works if you have one. Im guessing your voltage adapter might be bad. Could be the laptop one as well though.

nah, it should be able to run off the battery as well.

If the power supply is bad, it wont be charging the battery. Thats my point.
