Re: RCA CTC130 SCR



OEM if you can find it, also check the control circuitry around that device,
there are probably associated components that are also affected.

I have an RCA tv with a CTC-130 chassis. One day, it would not turn on.
Found bad line fuse and shorted HOT. Replaced fuse and HOT. It only
powers up for a second and shuts off (fuse and HOT are OK). Found a
shorted SCR, in the shutdown circuit.

What could have caused the SCR to short out? What should I be looking
for.

Also, how critical is the type of SCR used as a replacement?
