Re: laptop screen turned black but laptop still running

Hi Gang, I've been pulling my hair out on this one. Gateway Laptop M6316 with a 15.4" monitor, running XP media center. The back light is out. I tied two inverter boards and even replaced the bulb and still nothing. I checked the wires all looks good. I am at a loss.
Does it work on an external monitor? Can you see a faint image when you look at the screen in an angle? How did it die anyway?

Re: laptop screen turned black but laptop still running
I'd say the replacement inverter is dead or the video chip driving the inverter has been struck also. Repacement CCFL's don't die that easily unless broken. CCFL wiring is pretty simple, small soldering job. Measured the CCFL leads for bad contacts?

Case you have an high voltage meter (0-5000 Volts), try to measure the inverter output. Be careful though.

That's what I thought so I ordered a second inverter board from a different company and still nothing. I spoke to the customer about how this happened and she informed me (described to me) that she saw a large spark in the wall outlet. I figured an ark hit it.

Thanks

Re: laptop screen turned black but laptop still running
I have a Toshiba Satellite A215. Yesterday the screen went black during shutdown and computer did not switch off. I switched it off manually by holding the power button down. The monitor would not switch on after that and the computer would not enter the boot sequence. After reading this thread I tried removing the battery and holding the power button down for 60 seconds. This seems to have fixed the problem and the computer switches off and on just fine.

Thanks for the great suggestion and post!

Is this a sign of things to come? This has me a little worried about the remaining life of my machine. It is about 3 years old.

Re: laptop screen turned black but laptop still running
My Toshiba laptop decided that today was the day it was going to play up.
I turned it on today and the screen was black and I thought it just wasn't turning on, then realised I could still see the screen behind it. I restarted it a few times and it didn't work.
However, it's not jsut staying black anymore. It will start up full colour, then a few seconds in it will drop back to black.
I tried doing what has been said here, but I don't think it's working or I'm just not doing it right.
Can someone please give any other options in what to do?
I don't reallly want to take it to anyone because of the prices, and I need it right now for an assignment. >.>

Re: laptop screen turned black but laptop still running
Here's a new one...put a new inverter in and thought it didn't work, but with a bright light or flashlight you can see the start-up screen. After logging on with a user id, and using fn+f8, lights up just fine. Any ideas??
