Question about Sanyo 42 in. LCD TV
Picture and sound are normal but for what looks like a shadow that looks like a coffee spill or something on the screen.
If you can, send me a pic of the screen. You could have a impacted screen or a defective LCD panel.

Disassemble TV, clean all boards from dust, unplug/replug all connectors,
most are really small, be careful, try TV again. Out Same Model TV started off the same, left bottom of screen/shadow when TV was on for awhile, since then has got worst, like 2 shadow boxes showed up, now upon startup, TV is screen is covered w/vertical lines, shut off the TV once or twice and works fine until next startup. If the above does not fix TV, look at the top of TV from Back Panel Off, Top-Center is a board called T-Con board, replace it. All the info for this board replacement is on the Bar-Code Laabel and Board itself, ie; T370HW02 VC CNTRL BD, 37T04-COG, FX-5546T03C22 (orC21)-964-0000NMP-00629-03 this board is Mgr By AU Optronics. GoTo For Parts/Pricing, they have 180 warranty on parts, aprox $45.00 for T-Con . http://www.shopjimmy.com/auo-55-46t03-c22-t-con-board.htm

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

1Turn off your monitor or set the background color to black so you can easily identify spots that need to be removed. Step2Apply the distilled water to your clean, soft cloth. Step3Wipe your LCD screen in smooth motions from left to right, going from the top of the screen to the bottom. Step4Let the screen air dry or simply run a dry area of the cloth over the screen again.
