  • Samsung PD27AOQ (BN44-00506B) constantly blowing internal fuse.

    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.

    Samsung 46" TV LE46B530 blowing fuse
    by RogerH58
    Hi all,

    I am a newbie and not very experienced so bear with me if i struggle sometimes with technical language - but I'll do my best. I searched "Samsung" and the model number on the forum but didn't find anything I could understand!

    I'm not an electronics guy - just picked up stuff over the years through my flight-simming hobby.

    I have the above mentioned 46" tv as the monitor for my flight-sim setup. Recently it went "crack" and stopped working. No standdby light and no response. I assumed a fuse had blown and after investigation...

    Samsung BN44-006056A Blowing Mains plug fuse.
    by stav242
    Hi,
    ive picked up a Samsung UE32F5500AK TV with a BN44-006056A power pcb.

    It was reported as `blowing the fuse` - the 3A one in the plug.

    on quick inspection of the power pcb, a ceramic capacitor CM802 has blown apart.. photo attached.

    Ive found a PDF of the circuit schematic and can identify the neighbouring components (RM801, RM802) but cannot find CM802 on the schematic.

    Can anyone identify what CM802 is ?

    thanks.
    S....
