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.

LG 42LH90-UB tivo remote code problem


Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. The site has set-up code list & set-up procedure to many popular brand remote controls. The site has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Set-up code list to many brand remote controls also is given. Pull up older posts.

Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" to your device; to which you want set-up codes; in the "Search box at the top right of the display window" to get gathered related posts. .

I have a 42LH90 television which has an optical audio outlet, where do I get speakers and cable for this


You can purchase a fiber optic cable from Sears or any store with an electronics department i.e. RadioShack or Walmart or even a Fry's or HH Gregg and etc. I recommend a sound bar that has a digital audio input because it does not sound like you are interested in having seven speakers going all the way around the room
