Subject: [Techs] TA RCA P52812AB(PTK195AB)Dead..Was conver. issue


> I had a call originally on this for convergence going out after 30-60
minutes. Replaced STK IC U19700 and

checked every connector many times
> and can not find the problem.

> S/B voltages seem find(no print)..Best I can do from my notes is, pin 5 of
micro has 2.5v, press power,
> goes to 0 v.
> U14701 has B+, but 0v on either output. Replaced and still 0v..I
disconnected the output from circuit and
> still 0v, replaced, same problem..
> I measured these pins as I pressed power and the 5 volts for the output
comes up, but the 12v goes to a
> couple volts, then to 0.
> I've tried the troubleshooting guides, with no luck...or they don't apply
to this set.
> I am still at a loss what could have happened from the time I ordered
these convergence parts and replaced
> them..any ideas?
