Replace the defective electrolytic caps on the power supply and/or replace power supply, check at www.partstore.com That should fix your problem.

If you can open than open your LCD tv & checked Inverter Borad it have White & red color connector may be this board is defective.

Sounds like your resolution on your computer is set too high for your tv to accept. Try putting your computer resolution down to 1024x768 or lower and see if that works.

if there is a stanby switch for the remote, turn it off. wait for a few minutes then turn it on. operate the remote.
