Tried to resolder ZCD but still no power. do i need to replace the module parts # a-1415-722-a ?. thank you Roxel
Replace diodes D645, and D647 in standby power supply circuit.
Part# 6-500-567-01
Try replacing Q605, D690, D647 and Q690. These are all individual components that Sony techs have identified as being the source of the problem. You could try replacing one component at a time, but that would be time intensive. Its up to you! You could also become a premium member and request the "9 Blinks, ZCD/KV27FS320, KV32FS120, KV32FS320, KV36FS120, KV36FS320" information package, which was the source of this information.
It probably is not a fuse. If you can go into test mode it is not a fuse. I'm working on my daughter's tv 9 flashes. Purchased the manual so much for that it stops at 5 flashes. This is a zero crossing problem. I am digging and will come back when I find the fix. Many are stating replace the xxx diodes on the G board. Sorry guys no G board on this tv.
Look for an open resistor or diode or zenerD. in pwr sup. blown fuse first
