Yeah, let's all never learn anything new.

Would that have been your advise to Tesla or Edison?

Let's all just get warm around the lightning fire until it burns out.

The symptom does have some similarities to an electrolytic with ESR issues, if you are going to get into fault finding you really do need to invest in an ESR meter such as the *** Smith ESR meter, changing caps in a random manner is more likely to result in damage to PCB tracks or solder bridges which would certainly make the fault become permanent.

ian,

I fixed it.

You hit right on the problem.

The original IR receiver unit was mounted on a small PCB, 1 1/2" square. When I removed the old module and soldered on the new one from Radio Shack I may have fried one of the tracks where the pin from the IR module poked through. When I went to remove the Radio Shack module to try a new one, I noticed that the copper track around the little hole was gone. The solder around the pin must have made contact with what was left of the track, but it came lose when the unit warmed up.

I replaced everything with wire and it works again.

Thanks a ton for the feedback.

If I ever decide to get serious about repair work, I will look into an ESR meter. That and a bit more education.
