Zenith TV Model: SF5749W2 Unit clicks twice when press the power button but does nothing else. Checked caps, diodes(in the PS section) and the HOT, all good. Found a tip to replace C3434 and found a 470ohm resistor in it's place. Anyone know of a mod that required this to be done? Would like to get a print of the PS if possible. Any help appreciated.
