I would steer clear of taking apart remote to fix the problem you describe as it sounds more like a programming issue than a bad keyboard problem.

Assuming that you can get your hands on manual for remote, you might try using a different programming code for boom box and see if that helps. Manuals are often a bit vague about which of several program codes apply to a particular mfr-model pairing so trial-and-error
becomes necessary.

Unlike your experience with printer cleaning, trial & error solutions to software issues can be a bit more forgiving if one is careful to document initial settings. (I would also say, take care to make backup copies, but that doesn't really apply to remote control devices).

I don't have a manual with this because I bought it second hand and it was discontinued in 2006.

However, I was using the remote with a battery powered boom box. The back light on the display didn't light up in addition to the remote not turning the boom box on.

I just plugged in the boom box and both the back light and the on button works perfectly with the remote! Could this be a battery issue in the boom box? I've never encountered something like this before. It's odd.

Thanks for the info regarding not purchasing the repair kit. I think you are right.

Thank you both for all your help.

I'll change the batteries and look for an obsolete manual online. If all else fails, on to Radio Shack it is!

Have a great weekend,
