Hi Jasen
You should have a closer look at the standby circuit.or a shorted power
regulator. In short you are having power supply problems.Good luck.
Cliff.

> I am working on a Pioneer Projection TV from 1991. I was wondering if
anyone has seen this before? The TV will not turn on. When plugged in, it
will make a pop - pop - pop noise and the sound eventually fades out. The
power button has no effect. I am told that it used to be able to be
unplugged and then plugged back in and it would work for a short time. Now,
it just pops after being plugged in for a few seconds. I tried re-soldering
all the bad solders joints on the P/S board. No effect. I am down to
components, but I am hoping someone might know which components cause this
problem. Thanks for any help you can provide.
