Common failure was one of the main supply diodes in the SMPS, usually the
area of the pcb around the diode will be discoloured and the solder
connections appear burnt or charred. This will include other components
associated with that particular circuit.

Had a chance this weekend to take the wire out and check out the main
board. Checked for cold soldier joints but didn't find any. Checked
diodes but couldn't find any bad ones as well. What else could it be?
The set has no video or sound. Any information would be helpful.

Any charge has long since been disappeared, just take the HV lead our of
the splitter.

I have a Zenith PVY4665DT Television that I am trying to fix. The tv has
no video or sound. I am unable to get a schematic or service manual.
The TV has been sitting up for about a year. I tried to remove the main
module but the flyback wire is in the way. I am leery about removing the
wire because of the voltage stored in the flyback. If the TV has been
sitting up for that long, is the voltage slowly leaking out or is it
stored in the transformer?
