Television keeps losing picture

worried_jim

I have an LG 32" crt tv which I've had for 8-9 years and it has started turning itself off. First the screen will go black as I loose the picture and the programme sound will continue for 5-10 seconds before the television turns itself off.
I am unable to simply turn it back on again, if I do it just turns itself off again. Sometimes I can go all day with no problems but this evening it is doing it every 10 minutes. Is there anything I can do or has it had it- besides this there is nothing wrong and I am more than happy with it.

Sounds like power supply problems, is it built in or seperate ?

Check the remote isn't interfering/sending the shutdown signal/is faced away from the telly!!

If that's all fine, I suspect it'll be cheaper to replace the set which doesn't really owe you much at 9yrs...

It wont be power as it doesn't shot down completely at first the picture stops followed by standby mode a few seconds later- same for the remote. I did take the back off to see if it was full of dust and getting hot but it was spotless inside. The power supply is internal.

Yes it could be power. There are two different power circuits in a TV - a low voltage and a high voltage. A failure in the HT side would mean loss of picture but still getting sound and result in a fault condition being detected and the TV being put to standby.

Chances are its a triac, power transistor or dried out capacitor. However by the time you've paid for diagnosis and repair, you may as well buy a new TV and benefit from a smaller TV with lower power and built in freeview as analogue will be completely off in the UK in 2 years.

Good advice- its already consigned to the skip.

Took it to the tip yesterday and was amazed at the amount of tv's piled up there, I can't see that they were all broken, There was even a Toshiba laptop lying there.

Before dumping TV's you should of tested the new stuff as you might not be impressed. I wasn't.

Newer isn't always better! Most TV is still SD and SD doesn't look very good on most HD screens because most upscalers are quite poor.

I very much doubt you will be saving any electric by moving to a HD screen as the power requirement is about the same, sometimes higher.

I'm sticking with my Sony 28" until TV's and broadcast improve.

Because most people foolishly jump on the bandwagon like they do with most new things. They believe the hype rather than judging for themselves against the items they were going to replace.

You are quite right. I havent replaced it with a new one but got one from an neighbour. it is lcd 26" hd ready and it is no where near as good a picture as my old set but it will do just fine for now as it was free.
