DirecTV receiver R15 won't respond to remote RC23
Well, I took the DVR apart and found the power board completely intact, no bulging capacitors. However, the Mother Board had a 220uf/50volt cap that was bulging, so I replaced it. By the way, 'DigiKey' is the only place to go for electronic parts. They'll hook you up! The DVR still wouldn't respond to the remote. Darn it!
So I took both of my DVR's apart and swapped out the Front Board (the one with the Photoamplifier in it) and the DVR would now respond to the remote. OK, so now what do I do. I still have one DVR with a bad Front Board. I started to look on ebay for an old used R15 500 that I could swap parts from...remember, I own my eqipment and the goal is to preserve what I have recorded on the Hard Drive. R15's were going for around $50 -$80. Then I got to thinking. I still had an old non-DVR Direct TV Receiver in my closet I never planned to use again. My thought was: even though it wasen't the exact model receiver, it did use the same remote, so the frquency that the Photoamplifier worked at should be compatible.
So I took apart this receiver unsoldered the Photoaplifier. I then removed the Photoamplifier from my malfunctioning DVR and installed the part from my unused Receiver and it fixed it. So long story short(too late for that) the Photoamplifier was faulty. I tried doing some cross checking and a company in China called Raytron makes the part. The failed part did not have a part # and Raytron has several different Photoamplifiers that operate at different frequencies. This made it impossible to find the right part without schematics or knowing what the freqency is. So at least we now know what caused the non responce to the remote.
