Despite having a problem with USB Overload issue (topis still unsolved), my TV has started to act very strange.
Once I turn it on, it works fine for several minutes (or even not one minute), and then it freezes (screen goes green and with sripes, volume goes to the maximum and it "roars") turns off and resets. Duering the freeze the remote does not work.
Reset does not change a thing - it starts to loop itself (freeze and reset) and the only way to stop this is tu pull the plug from TV.
Did you have such a problems?
