Hi I have RV-B55 portable CD player. CD is not working, no rotation for the disck. cassette player needs to be replaced, where can I find parts of my set in Jordan. thanks.

SOURCE: Cassette player not working

Cassette players usually have a little rubber band that connects the motor to the spindles. If everything else is fine, I would suggest seeing if it slipped off somehow (or got cracked and snapped)

SOURCE: display light

This is the backlight, bulb 9V. must be repaced, i suggest to replace by a 12V. bulb
Unit has to be disassembly. Good luck

SOURCE: I get very loud feed back when i put my jvc rv-b55

Could be down to some faulty capacitors on the Output or Input side, these can sometimes go open and cause voltage spikes which would explain why the speakers are moving strongly in and out. Id see about getting the capacitors changed on the audio board, or see if any of them are buldged. The capacitors look like small cans and can be either blue or orange with a black stripe down one side.
