Default Zenith SR3587DT Sound OK, No Picture????

this is how I work, my technique of troubleshooting is half and half, both
expermintation, and troubleshooting, but it works for me everytime.

one more thing, the square wave pulse is continous, its not shutting
down, probably because its not getting to the flyback, or the base of the
HOT, it dies off at the driver xistor. its there on the base, gone on the
collector


Forgive me for being blunt, but it sounds more like you're experimenting,

not
repairing.

You should have checked the simple stuff first, like bad caps or even cold
joints, but you automatically assumed that it was a major problem.

When you thought it may have been a cap, you shunted it in circuit?!

What you should have done was take the suspected cap out of the chassis

and
tested it for high ESR and to see if it can hold to its rated capacity. -
