Power button on remote unresponsive

[Kando]

It seems to me that some remotes were made with some sort of chemical filled pressure sensitive areas, aligned with the upper pressure buttons. When these chemical filled sacs would start to dry up/solidify, the heating, via the hair dryer, could reactivate them to a degree.

That's just really roughly what I seem to recall about certain remotes, and how they could be dealt with when aging. There was no amount of cleaning that could otherwise help with the situation because the chemical filled sacs were of course completely sealed.

Maybe I'm not recalling this correctly, but that's what I do seem to recall. Haven't really paid much attention to remote construction in quite some time, so not really sure precisely of the typical make-up anymore.

Apparently some the silicone hasn't sealed properly when the pads are manufactured hence over time the frequented buttons go bad

Any remote is going to wear out in time. Especially the buttons which are pressed the most, like the Power button. It's essentially just some plastic bubbles over the top of some flimsy contacts. It can't stand up to repeated use.
