How to open jvc boombox speaker - JVC Audio Players & Recorders

take off all the knobs and it should come apart

Hello
Casette tape can be reeled to the capstan shaft and jammed. It is a tricky way to get it out. Only an experienced service technician can do this work. If you try to pull the casette hold tray out by force, it will get broken, and will turn irreparable. OK.

You can download the manual from the manufacturer's web site at

Hi, to find dp-100 ( since it is an old product), but if you don't mind you can seek the equivalent jvc product here : http://www.dealtime.com/boomboxes/jvc-rv-dp-100/products

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.

If you cant fix it, sell it to me for parts

You need to take the unit apart. If you pull hard to open the door, you`ll break the plastic connector that moves the head up and down.

Here you go. Click on instruction manual download. Hope this helped.
