JVC RV-B99GY Kaboom Boom Box problem

Check for a small transformer that delivers a 5V standby voltage. There ma y be poor solder connections around that area. No standby, no CPU and no c ontrol. The 5V will drive a crystal that is what the CPU is based upon. E ven the chassis button is read by the CPU.

I've brought home boomboxes that wouldn't work, unless they had batteries. At least one required some AA batteries (which were in addition to any D batteries needed to run it off batteries). Even running off the AC line required those batteries for proper operation.

It's not unlike many a digital camera, that has some button cells for housekeeping in addition to the AA batteries needed for actual operation.

Thank you, i'll try this after I get done checking on the outside.

Thank you, i didn't even think of AA or button cells. If it takes those and they became corroded or slipped, or just old, it would be a problem. I must investigate.

do anything to this radie i'd like to get a few >suggestions, please. TIA. "

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 prob lem in the CD drive screwing up the whole system. I work on Karaoke players and if the CD drive gets into a knipshit 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 probl ems first and then for bad filters. That usually works the best these days.

Thank you for the advice, i'm new here not on the internet. I do try to be polite when asking for help. Anyway, my husband doesn't want me to try to f ix it, opting to leave it running 24 hrs. a day. I work on things more comp licated than his radio and usually fix them. I offered to fix it, so his pr oblem now. Thank you all for your suggestions.
