Broken Futaba FP-122JE 27Mhz AM receiver

the FP-122JE rx

My Futaba FP-122JE 27MHz AM receiver is not working. I was playing with my rc and all of a sudden it was not working.
It seems the current is not going through, I have checked the current going in and it's good, but it won't let it go to the servos. The servos are anolog.

Did you remove and replace the crystal, that's always an obvious thing to check. It could also be a 'dry joint' somewhere inside the circuitry. You should be able to take apart the casing and examine the circuit board, but finding something wrong isn't easy unless it's very obvious (like a connection burnt out).
2 channel receivers are cheap to buy, you might be better off replacing the whole thing, any make rx will do so long as the crystal matches the tx.
