"I'm new here so I don't really know all the info I should post. Before I do anything to this radie i'd like to get a few suggestions, please. TIA. "

This is an unmoderated Usenet newsgroup which means you can post anything you want, even threaten someone, but they can find you and if, well you know the rest. I mean if you are a registered CCW you probably are better off threatening the government. Anyone on the internet can read what you post.

"I have a jvc rv-b99gy Kaboom boom box that once turned off will not turn on again with the power button or remote."

This is not good. It does not sound like bad filters or anything easy like that. Sounds like a software problem, or, as I found recently a hidden problem in the CD drive screwing up the whole system. I work on Karaoke players and if the CD drive gets into a knip**** it can confuse the microprocessor..

In those cases, unplugging can work, like it did for you.

In this case I don't know what to tell you. Just watch for mechanical problems first and then for bad filters. That usually works the best these days.
