Hello,
I have a typical rubber-dome TV remote where I'm facing the opposite of the "normal" problem. Instead of a button not working, I have a button that is always active.
Even after removing the rubber-dome panel and having only the PCB exposed, the button is still always active (I can see that, because when I put the batteries on, the TV LED keeps blinking. Only stops when I remove the battery).
I tried cleaning it several times with Isopropyl Alcohol and contact cleaner to no avail.
How should I go about fixing this? I am on a complete loss as I don't see anything that captures my attention.
I have attached a picture of the PCB and a close up of the circuitry area in case it's relevant.
