I am having a weird problem with a walkie talkie. It won't turn on, but if I pull the battery out, and give it a minute and put them battery back in, it will turn on. But if I turn it off, it won't come back on unless I remove the battery and let it sit again. It's weird.... Any clue?

I would assume that it has a bad capacitor on its circuit board. I say this because it seems to work for a bit after it is fully discharged and power is re-applied.

You might be able to disassemble and visually identify (and replace) the defective component(s). It really depends on how old your walkie talkies are and how they are built.

Good luck!

Capacitor is what I was thinking given the time effect. Anyway to tell if a capacitor is bad besides it being swollen/blow up?

Yep, disfigured, discolored, etc.

They look fine except they have this translucent yellow gunk on them, but I think that is just a glue? They all have it. Even the walkie talkie that works fine.

Likely one of them is defective internally and just not showing. I suppose you could spec each component and then break out your multimeter to manually check each one in the attempt to isolate the defective unit. Since you have a working device, you might even be able to do a direct comparison, one component at a time, to troubleshoot the device as well.

And how about to tell us the exact brand and model instead of guessing what the trouble can be? It will be much easier for you to check Cn, Rn, Qn instead of discussing which capacitor has a glue or something. There're a lot of service manuals on the net, maybe for the WT's too . . . .
