Hi, whats the power board number (BN number)

I have had problems with one particular board switching the set off at random (such as when a high wattage device like a kettle) was switched on off teh same power line. It was a problem in the PFC circuit.

Do you have any voltage from the main board to the t-conn?

Check the t-con for a short or an o/c fuse

hi sparky . t-con is at the top . have disconnected the 2 cables that go to the screen and it still must have a short on the board because the fuse heats up and p/supply ticks

If you have a psu fault as well then I'd recommend ignoring any advice given, apart from that accidentally posted..
