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
sometimes it works for a hour or so is it still the transformer?
thanks sparky

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
