Looking for some assistance please.
Trying to repair a PD27AOQ samsung power board.
Initially had the typical problem of cm806 capacitor blown, additionally thermistor NT801s blown.
Replaced the ceramic capacitor, str60252s, bridge rectifier, thermistor and fuse.
Testing it the fuse blows immediately power is turned on.
diodes dm852 and dm853 test as shorted when in the board but fine when removed.
any assistance, guidance would be appreciated.
