This is a very frustrating thread to follow...
I don't understand why the remote was pulled apart - never an easy or harmless operation - when it was apparent (from post #33) that it was producing IR signals. If there was any doubt about the timing of these signals, then simply connect a 'scope to the output of an IR receiver! Yes, remotes can fail, but overwhelmingly it's because of bad battery contacts, worn buttons, dry joints (usually on the LED when it's exposed at the end of the remote), physical damage, etc. I've never had to change the resonator in a remote. Perhaps I've been lucky.
Earlier, we established that the fault was apparently the super-cap, and that the remote was absolutely fine (leaving aside the "user error" that meant that some of the buttons didn't appear to be working, when really they were producing codes intended of other equipment). So, given that the receiver had been comprehensively taken apart and probed, why was it most logical to assume that the remote control had suddenly stopped working? First rule of a bounce is, surely, "what did I disturb?".
How long had your replacement supercap been sat around? In your shoes, I'd go straight back to that - they have a finite life, whether used or not. Then, I'd get the 'scope out and follow through the signal from IR receiver until it reaches the microcontroller. Looking back over the thread, I see that I urged you to do that, but see no evidence that you did. Are you struggling because your working Philips 'scope is still in your house?
