Re: Remote control

You need to resurface the contacts. Here's how you do it:
First, disassemble the remote. Clean the black foil pads on the circuit board with rubbing alcohol. Now take a #2 pencil and a razor and shave the graphite from the "lead" onto a piece of paper (hold the blade perpendicular to the lead, this results in a finer powder). Now that you have a nice pile of powdered graphite, blot a Q-Tip into it to saturate the cotton with graphite. Rub the graphite onto the little black pads on the rubber button membrane, and be sure to apply more graphite to the Q-Tip every 2 to 3 buttons. Blow off any excess graphite. reassemble remote and test.

Hello i have a jvc rv b 90 . Ive insert the casette wrong. Now i cant open the casette deck anymore.

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.

JVC RV-B90 Boombox,How many watts in RMS and how much?

If you can believe what they say about the specs...

Register and download the manual for free at

Bear in mind the power spec is at >>>> 10% <<<< THD without any bandwidht specified. THAT's a lot of distortion stated in a meaningless fashion to convince you to part with the money.

If one looks at the power CONSUMPTION figure (43 watts), one can conclude that the audio power spec is totally fabricated. NO device puts out more power than it consumes.

That is not to say it won't sound good and loud in certain settings and conditions, but this is not, say, a Bose Acoustic Wave Music System. After a certain volume demand it will just be annoying instead of entertaining. That's why they called this class of product a Ghetto Blaster.

I see one sold for $70 last year...

Hi...every time I turn off my RV-B90 I have to unplug it and plug it back in before I can turn it back on. Any fix for this?

This was happening on mine and here is how i fixed it.

I would hear clicking from the cassette area when i first turned it on, and the door would be jammed and i had to brute force it open. The kaboom would not shut down by using the power button or remote. Nothing!

I found the tape mechanism was getting jammed out of place because of all the gunk so I cleaned the inside with isopropyl alcohol and a q-tip then moved the mechanisms back and forth with my finger on the bottom where the tape goes over the sensor.

I powered it up with no clicking and was able to shut it off with the power button and remote again. My power issues had to do with the tape player whodathunkit.
