My tv switches off when it has been on intially for about an hour. Then it will not turn on again for about 15-20 minutes and when it does it will switch off again after about 20-30 minutes.
Is this an expensive item to put right?
Is it something for an expert to do or is it something someone can do with a little knowledge.

your crt is getting weak you can get around this buy adjusting the screen control ...... the screen control is on the small board on the back of the picture tube . remove back , with picture tube flashing adjust screen control a touch one way will make it worse and the other will stop the flashing . only move it as much as you need to - no more . this will work for a while and you can do it again and again when ever needed . but the picture will not be as good .... as far as the free dead sony , i would get it . changeing a picture tube from doner tv is just plug and play on a sony . so you can have a new tv for free with just a little work ..........if this answer helped please rate it 3 or 4 stars . a high rateing will help keep mein the paid answer department thanks
I have a 42" LG LCD TV and just experienced this today. Watching cable,
then the screen went to black, but audio continued. I pressed the guide
button on my remote and pic came on with my guide menu. But then went
to black again 10sec later and has remained that way for nearly an
hour. Tried switching off both cable box and TV, disconnecting and
reconnecting cables, but no luck. Finally unplugged mains, waited a
minute, then turned back on. Everything seems normal now after the
Sounds as though there is an intermitant, heat-related problem with the HV transformer. You can order this at a tv parts shop or from Sony (probably more expensive) the part number should be on the part or on a schematic. If not, the parts dealer can look it up from the model number.
Well, the only thing that seems to be working so far is to plug AV cables into the "input 2" ports (on the front of TV). I plugged in my PS2, without turning it on. It has not switched at random since (about 30 minutes - it had been switching off and on for the past 2 hours). Anyone else have similar success?
