Would appreciate any help, comments.

I believe the remote receiver on my TV doesn't work anymore. I talked to a part supply store that recommended part 23085628 (RPM6938) as a replacement. The part looks like a photodiode or phototransistor but has three leads. I was expecting a module, something on a little circuit board which I could swap out.

I would not have a problem de-soldering and then re-soldering the new part. I'm just not sure whether this will fix the problem.

I think the only way to tell if the photo sensor is working is to hook up a scope and watch the data output while you press remote buttons.

Or you could just replace it with a new one. Also, make sure there is voltage on one of the 3 legs.

Ground, Signal and VCC on the pins. Scope signal pin will tell if receiving pulses. NOT "brand" specific. The microprocessor will determine if you are using the correct brand of remote or not. Cool
