Question about LG 42LH90 42 in. HDTV LCD TV
How long have you had your LG TV? LG had a problem with a chip on the main board in the fall of 2012. Most units have failed by now, but if you only watch your TV occasionally, this could be the problem. The symptom is this: Plug TV in, red LED on front lights up. Try to turn it on, red LED goes out and stays out (should flash and turn blue). Hope this helps. BTW, if it is the chip, and you're handy with a soldering iron, you can buy a new chip online for less than 20 bucks and install it yourself. A main board (with the fixed chip) is about $150.
