 Hi everyone , picked up an JVC RV-DP-100 Kaboom box on a local classiified site for $10 .. came with remote, strap , pouch for remote and power cord.


 Problem : Unit would sit in standby mode, when pressing the power button , it would power on for 3 seconds then shut itself off.


 After some research , even tried resoldering circuit board connections , freshening the joints. Didn`t work , same problem.


 Removed the top carriage that houses the cd player and 2 other boards , one , the middle one , contained the IC`s ..

 Carefully reassembled the unit , and no power issues at all.


 The cd player works, the cassette needed a belt and a slight azimuth adjustment .. The new  owner of this $10 Kaboom, is very hap-pay! :-)

 Just figured would put it out there in case someone else ran into these types of problems on their kabooms...


 Have a great night everyone! ;-)

I have the iPod version with a power issue. Might have to try this out. Won't turn on at all. I'll tear into it after the holidays. Thanks for the info.

Thanks for these pics.



I am the original owner of one of these. My problem was that it would not power on with either the AC cable or with D batteries. I took off the back cover and jiggled some stuff around. It powered on. More specifically, when I apply some firm pressure onto the DC connector, the speakers pop then it powers off. I will completely dissemble the boombox to get a better look at the board. I'll take a look at the ribbon cable pins too.


I have never used the DC connector as I do not have one.


PS: what the heck is with XXVII, ยง 3, Part 2, of subset "D"

My guess would be either bad cold or broken shoulder joints where the socket goes in the board.
