SOURCE: screen went black on my 42" sanyo model dp42647 lcd

Hi there! The panel may be in protection mode. The Inverter board is the most logical area to start after checking power supply Voltages.(5,6,24 and 13Volts). There may be coils on the Inverter Board which have bad soldering or faulty. Other than this it may be main board which controls switch on or off. If all else fails, refer to a repairer. Beware of High Current!!! Best Wishes and Good Luck, Jus004

Sanyo plasma tv screen is black and theres no sound, but the green light is on.


No sound and no video is usually means the main board is bad. Green power indicated power supply might be OK.

Vertical lines across my entire screen


My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.
