Re: Samsung 920NW 2 Seconds to Black
Did you just try the test bulb on its own? try again using it to replace one original at a time.
Also - if your board is same as post1 ,set off (unplugged) for 5mins test the secondary resistances on the two inverter transformers - see attached pic Meter on ohms 2000 test S1 to S2 and S3 to S4
and post results
