I have one of the above 2 televisions in my house, dont ask me which one, as the stupid idiot that designed this model series of TV forgot to print the model number on the front of the set, Ive had it a few months and its worked fine, now its started producing a mainly green picture, with very little contrast and it keeps switching itself off after about 30 seconds to a minute, it did this once before and I switched the plugs round and it did the trick, now I try everything and it keeps doing the same thing, Ive also tried losing my temper, swearing at it and threatening to whack it with a sledgehammer, Ive tried punching and kicking it, ha ha only joking, but seriously, has anyone got any good practical ideas to make it go back to normal
