Hello,
My TV made a loud bang a few weeks ago and went dead. I searched online and found out this is so common with these boards that they sell kits to repair them. I opened the tv up and removed the board for testing. The main fuse was blown and the two Mosfets also.
I checked the two blue capacitors in front of the Mosfets and they were good as was the the Diode on the same heatsink and the two blue capacitors in front. I ordered new parts from Digikey. I plugged it in and got the same result, Two Mosfets shorted, one fuse burnt
I have searched for a schematic for BN44-00874C but no luck. Would someone be able to point me in the right direction for what to check next. I posted a picture if this is any help.
Thanks.
