My computer went blank while in service, and thereafter it no longer comes on, what is wrong

This might not work but may be worth a try. Press and hold the start button for about 10 seconds and release. Wait another 10 seconds or so. Press and switch on as normal. It may take longer to start up than is normal but wait a minute or two.
Like I say, it may not work but give it a go.

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.

Chances are your screen went defunct. Or it could be a problem with some other piece of hardware. You can try using the USB cord to plug it into the USB port on a laptop or desktop and see if the computer can read the files. If it can display and explore folders and files, chances are it's the screen (display) that went south. It it can't display and read folders and files chances are it's the memory or some other internal hardware that died. Sadly these things are cheaper to replace than to repair. I have a Kindle II with a faded out display. It works but the text is so light that it's barely readable so I retired it. I have a Kindle Touch that I dropped and the screen broke so I ended up getting a Kindle Paper White and I like it the best of them all.

Hi,
1) You should try restarting it, maby that will solve the problem.
2) If that does not happen, then go to a computer specialist, there maby is something wrong with your Display.

Your hard drive may have gone south. Remove it and check with diagnostic software. Bad sectors in critical areas of operating system data will do this.

Apologies, this is not a solution, but just to say that I currently have exactly the same problem. Have you managed to fix yours?
