Hi thoma,
You didn't mention set model or screen size. PLCD190 has a couple of troublesome caps C537 & C100 both (100n/630) and usually orange. Had others that smoke, screech and go off with nothing obvious. Guess inverters are Darfon as in the 32 inch version 32PF5520.
Thanks Jordan - hadn't got that one.
Good luck - Chris.
