    Problem with Samsung HT-DB120

    Hi,
    this system has mainboard HT-DB120/THA25.
    Display working and also i can switch modes, but there
    is no audio.
    I noticed that resistor R100 is heating up.
    I found wiring in attach, but there is diferences.
    1. In this wiring 1st pin of resistor is attached to diode bridge and
    second pin is attached to Collector of PQ5. On PCB is not the same.
    2. Resistor R100 is labaled as 10ohm, but it is 22ohm. Even colour
    code (red, red, black, gold) show 22 ohm.
    3. Emitter of PQ5 must go to PIC4 (7812), but this also is not true.
    So, it seems that this is not right wiring that i found.
    I check also other 5-6 sites, but all is the same.
    Can somebody help?
Working...
