Hi Al, These tv sets that have the 2 wide flexies going to the panel return an SOS to the main via these flexies, so there is a hot chance your screen is faulty.
Unfortunately with these,  you can't disconnect one flexy at a time to see if you get half the screen white - you only get a dimly lit screen.

So, its not the p/supply, main board or LEDs, and there is no T-con. Doesn't leave much else - have been caught like that myself.
