Subject: [TechAssist] help needed on a RCA ctc169 au2
> Hi all.
> Have a little troublemaker here. It is a RCA F31226es with a ctc169au2 in
it.
> It was dead. I replaced the regulator ic, u4101, the 3 caps in the power
> supply, c4108, c4102, cc4104, and the diode cr4122.
> Now I have b+ BUT still a dead set.
> The power supply 15va is down to about 5 volts. If I open jw324 the volts
> rise to +15. If I open jw320 it stays low. I opened the collector of q4601
and
> the resistor r4602 and it stilled stayed low. Any ideas>
> Thanks in advance
