Question about JVC MX-J900 CD Shelf System

1 Answer

Cassette player will not work

Love my JVC MX-j900 CD shelf system. I have hardly used it since it has been in storage due to moving. When I unpacked it (it was packed properly, lots of packing) I found the tape player will not play at all. I put a cassette in and push "TAPE" and hear a couple of "clicks" and that is it. It will not rewind, fast forward or play. I have tried numerous tapes to no avail. I followed the manual instructions by unplugging the unit but nothing helps. It feels like I might have hit a pause button or something but cannot find one! Would be grateful for any ideas. Moneydude

Re: cassette player will not work

Common fault on the JVC tape decks is the belt stretch and then it does a clicking sound its trying to pick up the audio heads. changing the belt is quite hard if you have`nt done it before.

No sound on speakers, only on earphones.

Indicates to me that the headphone socket is faulty, assuming that previous to this putting a headphone jack caused the main speakers to cut off.
Not an expensive repair.

Have a jvc MX-J500. (purchased as a previously owned unit) When a cd is inserted in any of the three trays it just says "no Disc". Radio works as well as the cassette player. System was dusty but appeared...

You could try a CD lens cleaning disc which will clean any dust off the laser lens. But it is possible the laser power can be low if it is an old player. this will stop the discs being read fence the fault No CD as it cant see the disc. This will mean either a new laser assembly or complete CD deck. Try the cleaning disc first and if that does not work take it to a service centre or just use it as a radio cassette in the garage.

I have discs in my cd player but it says NO DISC.

The "no disc" messing indicates that the disc is not readable. This can be due to a dirty lens on the optics or defective optics. If you can gain access to the CD section, try cleaning off the lens of the optics assembly using a cotton swab and alcohol. Let me know if that does not resolve the problem.

No sound whatever

when you switch the unit on make sure that you hear two clicks, this will tell you whether the protection relay is working. Should you hear the two clicks this will indicate that the audio ic`s are working. There are fuses inside the main component box, four on the transformer. Let me know the outcome

CD Changer & Tape Deck


- Disassemble the player.

(you will need only one, long, phillips head screwdriver $5.00)

[It is a tedious job. (first,study how it is put together) There are 6 screws on the back - three down deep holes, three at the bottom, and two dark colored ones on the side. Once the front covering is off, then you start the process to get at the Cassette deck. You will have to unscrew a ground wire; pull the "tape" connections and one wire bundle snap fitting; and then unscrew the two screws on the back, near where the wires for the speaker connections are placed... then remove the Cassette Deck.]

{I sat in my recliner with the whole thing in my lap as i worked with a foot stool near by to put things as they came apart... and i used a metal salad bowl to through the screws into as i went along.}

- Study the drive mechanism.

- See where the drive pulleys are.

- Use small elastic bands to replace the broken belts.
(small = 1/2 inch diameter ... the size of your little finger, but will stretch out to two inches or so.)

I happened to have these on hand:


- I did this on my JVC PC-XC70BK and it worked.

- Both the player-side and record-side decks had broken belts.

[The fast forward and rewind wouldn't work on either side.]

(Per each deck: one drives play, one belt drives both Rewind & Forward)

- Now both decks work.



- My guess is the laser pick up is dirty (because they all face upward and oily film builds up on them).

- First try a disk cleaner with a brush on the underside of it.

- If that doesn't work, then (after taking off the front plastic cover plate {see above}), you can see where the upward pointing laser lens is. If you can, use Rubbing Alcohol on the end of a Q-Tip to probe into the area and thoroughly clean its surface. Then wipe it clean with a dry Q-Tip.

- If you can't get at the laser lens, then Disassemble the Unite.
[There is another ground wire that must be unscrewed from the deck assembly. And there is the issue of the tape connections leading to the top part of the unit ... they will flop around and fall out of their place once you have pulled them from the connectors ... with a bit of observation you can get them back correctly.]

- Unscrew two screws at the back ... then pull out the tray assembly.
.... then go as far in the disassembly as you need to so you can swab the laser lens with the Rubbing Alcohol.

- Re-assemble. I had one screw left over.

... ROTFL but i know where it goes and i don't care to get it there... so to hell with it, right?

Everything works fine now. Not bad for a 17 year old piece of equipment that has a Ten CD storage tray... that you can't get anymore... right?
