- dumb question
-
- do parts "burn out" in remotes?
-
- i have a cable-tv box (Zenith, marketed as a "wonderbox", a
- converter/descrambler/remote all in one)
-
- every couple years or so, the remote will spontaneously die.
- not battery. not crud build up on sender/receiving units. dead. kaput.
-
- since it's rented from the cable company, i simply take the remote part
- in, and they give me another one.
-
- however, in the last year i picked up an old vcr which uses a Zenith
- remote that looks the same (a few more buttons for vcr controlling :-)
-
- a week ago, BOTH died at the same time. i used both about 10 minutes
- earlier, no problem. i go back to them and neither work.
-
- well, the cable company replaced the converter remote, but i'm stuck
- with a dead vcr Zenith remote.
-
- i'll probably buy a low cost "universal" with Zenith preprogrammed into
- it. but...
-
- i'm curious, what is the weakness. what dies? is it fairly easy to fix
- perhaps (replace leds?).
- do spontaneous static discharges from sitting on the couch material or
- carpet floor do them in or something?
-
- even if i buy a universal, this is starting to bug me. am i somehow
- assasinating the things? i hate mysteries.
