My LG TV turns off by itself. Is it worth repairing?
it depends on how old the set is, and if you can find some one who will work on it, most problems with a LCD tv, is that one of the boards goes bad, there is a main board, and a driver for stero, and channel functions, if you can find some one, let them give you an estimate for how much it would cost, no harm in letting them look at it, but beware , parts are not cheap, so cost for new set, compaired to repair, equals what you should do
