Question about Polaroid FLM-323B Television
Ok first off I have spent hours tracing and drawing the schematic for this power supply. It is the 200-PO0-MLT666A-AH.
It was blowing fuses. Q2 and Z1 were shorted. Replaced them and got a red light. Hit the switch and got a blue light for about 5 -10 seconds Then the fuse blew again. This was with the inverter board plugged in. Now the the fet and zener are shorted again.
Nothing on the inverter board shows a short. But I wish Id a tried it with the inverter unplugged. Ideas????
Replace Q2 by 18N50, Q8 and Q9 by STP6NK60 and Z2 and Z4 by !n4739. I have the same problem and fix it.
