Image lost after 5 min turning on the tv, sound was ok.


I would suspect overheating of an electric component in the power supply of the lamp (backlight) of your lcd tv. bring it in for repairs.

Screen blackout


I had the same problem and fixed it with a new backlight inverter board. It was a pretty easy install. The part is available on eBay. http://cgi.ebay.com/New-Inverter-for-Dell-W1700-17-inch-LCD-TV_W0QQitemZ400017456720QQcmdZViewItemQQptZLH_DefaultDomain_0?_trksid=p3286.m20.l1116

Sony lcd progection tv kdf-42we655


You can accomplish this by unpluggin the tv for 4 hours. When you power it back up the internal software will revert to the original factory defaults.

Vizio GV42L LCD TV screen black when turn TV on first time


If you are using a set top box this might be caused by turnig the box on at the same tie as you turn the tv on or slightly after you turn the tv on.  If you are using compnent or HDMI inputs the set needs to see the signal as it is turned on to know what formt the signal is in.

Tube turns on nothing else does


If the Tv turns on (power supply is ok), screen lights up (inverters are ok) but don't get a blue screen, menu options, source options, or audio, it's most likely the main board (aka Motherboard) is faulty. If a DVD player is hooked upto the TV, check whether you can get audio from that (change the source using remote), in such a case it could be a problem with LCD Interface board. My $3 is on faulty Main board.
