The screen on your laptop is iluminated from the back by some CCFL tubes - these are not functioning because either they aren't powered or they are broken. To find which you must open the cover of the screen and test the lamps.

I have a new tablet, charged and protected but when I was changing contrast settings it went black and I cant get the screen to come back on past startup


Sorry about this.
Well, seeing it is a new tablet, either of two things can be done.

Your tab is booting beyond Startup but you ain't seeing it because of the contrast/black screen setting.

To confirm; step into a dark room/space and hold a flashlight very close to the screen, you'd see your tab is at its home screen already.

Anyway, you will have to default factory reset it as it is or you could attempt to navigate (while in the dark room/space and using/holding the flashlight) Swipe to open/unlock it----Settings----display and brighteness-----brightness----'move cursor up to increase brightness'. Done.

Second option with dark room/space is tedious and strenuous.

Factory/hard reset is an easy option to try.
At the same time, hold/press both the volume up key/button and the power button/key.
Follow the system prompt afterwards.

Or

Press/hold down the volume down button/key and the power button.

Follow the system prompt thereafter to factory/hard reset your tab.

Best of luck.

Gpx 32 inch lcd hdtv has sound but no picture


In a very dark room with set on use a flashlight at the screen--if you see a very faint image of the program it may be the back light this set uses for brightness on the screen.

Vizio HDMI HDTVmodel VW48LHDTV10A TV sound went out and the picture got dark from outside of the screen


The inverter board is common on this set to go out, once dark then you can use a flashlight to determine that it is bad, 2 in away from screen and you should see the picture in background, the sound is something else, it will be located on the main video board, look for bad caps bulging out.

Screen is dark (like there is no power on it)


Well if you take a strong light like a flashlight and you can see a faint image. Then the lamp (CCFL) or the lamp's inverter has failed. It should work fine with an external monitor. Still not good though and usually expensive to repair (unless it is still under warranty).
