Picked up a non working LA46B650T1F. Opened the back up, and the fuse near the AC in (FS801S which looks to by a 6.3A slow blow ceramic) was blown.
Further visual inspection showed the thermistor at NT811S (marked SCK 084) was cracked at the top. So i am assuming something else is shorted to cause the fuse to blow and the thermistor to crack? Am i on the right track?
What else can i test - the power supply board is a bn44-00265a, and can't see any specific threads on this board, nor find the schematic. I see some similar samsung boards, there are suggestions to test components on heatsinks - any advice on how to test these for shorts?
Note the attached board pic has the thermistor snipped out, so i could identify it
Ohh - and is there an equivalent for the SCK 084 thermistor - doesn't seem readily avaialble here in Australia
Thanks
Rob
