Hi sparky
Most likely the inverter transformer. Think its two symetrical transformers in one package. They seem unreliable on this chassis. Have seen a few where one transformer is o/c causing the backlight to trip while the rest of the set works. Transformer doesn`t seem to be available anywhere though.
Regards
John.

hi sparky
if the transformer has the number tms91429ct on it, it is a stock fault and you can get them at sparedparts.com.
hope this helps

hi sparky
they normally will only give you a picture for a few seconds before the inverter shuts down, all i can suggest is you try warming or cooling  the transformer first before you switch the set on and see how long it lasts, its possible it has an intermittent open circuit,
good luck

Hi Sparky,

But you got yours from Ebay - rather more than a tenner - thought you were poor, like Norfolk folks - Chris.

Congrats Sparky,

Was just the wife complaining that I coughed while watching 'Dave' after 9.00PM when she is tucked up reading yet another husband murder mystery.

I said it was laughter, and was wearing cans so that that Fry chap downstairs wouldn't interfere with the butler in the library doing something quite nicely wicked to the upstairs maid, so didn't note the prob.

Thought it simpler to stop the weed and kick the shit out of Profilo and Vestel - they need it - Chris.

PS - am shocked to discover you admit making a pound - are you quite well  ?
