  1. This TV was dead but I found 5 parallel i ohm resistors o/c (not
    burnt) in the SMPS. Replaced and now emits regular faint clicking
    sound.
    Anyone got a circuit diagram please? - I've searched everywhere.
    The SMPS uses a 16 pin TDA8380A and BUW13 NPN power transistor with a
    CNG82A optical coupler for the feedback. What is it safe to try?
    Don't think the transisot is faulty.
