Question about Polaroid FLM-323B Television
This Tv is blowing fuses Shown is a partial schematic and a data sheet of components involved.
Q2 and he Zener on the source were shorted. I replaced Q2 with a FVP 11N60 and the zener. I then had 5VSB and led lit. I hit the on/off switch and the led turned blue then in about 5 seconds the fuse blew again. Q2 and the zener are shorted again. The source has 5 resistors to ground all marked 1R5 which I take to be 1.5 ohms.
I did peplace the 2 infamous caps in this power supply BTW this is a 200-P00-MLT666A-AH I do have the full schematic and working on a parts list with Mouser stock numbers and digital macros of trace brd to sell later on.
There are no other signs of bad components or ohmed shorts.
