Maybe someone has encountered this before, can help us with this?
Customer said this set was hard to turn on , sometimes after a few tries ,
it would finally turn on.
Before that, the color / convergence was off (bad).

When I tried it, the relay would click but no video, audio, or h.v., but
sometimes the power light would come on, then back off.

I replaced capacitors on the converg. board, and on the main board - pwr.
section.
I don't know if the regulators are damaged or which reg. to check or change.
If anyone can help with this, I will appreciate it very much? Thanks.
