CD Changer & Tape Deck

My CD Changer on my JVC MX-J900 no longer will play cd's and my tape deck also no longer playes tapes. The CD tray opens and allows me insert tapes, but does not play them. The neither tape deck will not fast forward rewind or play. Could you help me find the problem.\ Thanks.

    The cd changer won't read the cd's or even open. When we bought it it read the one cd we played then we removed it and loaded it with 5 original cd's and it has not played or open back since.

- 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:

CD Changer & Tape Deck - 12_1_2013_4_19_19_am.jpg

- 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?

Not all cd tapes play clearly out of 12 tapes ,4 sound ok ,8 soundwrak

Are these all commercial pre-recorded tapes? Or are they tapes that were recorded at home? Is the tape deck one that the tape loads in from the short side and must be flipped around to play the other side....or is it one that the tape loads in with the tape facing in and is auto-reversing? Pre-recorded commercial tapes should work on most machines without problems. Home recorded tapes can be a problem, especially on the type of deck that the tape must be swapped over to play the reverse side. Many users use C90 or C120 tapes to home record. These tapes are thinner than normal tapes and are prone to getting overly tight and then can break and/or stretch. This causes jamming in the deck and distortion of the playback.

How do I get it to record a voice?

Many portable 'boombox' recorders do not include a microphone for recording ambient sound, but can only record from one internal source to another, like radio or CD to Cassettte. Some do include an input jack for microphones or other audio sources, but you'll need to check your device's specs/ports to be sure.

It is possible that your Cd and teh tape section has a belt problem. The loading belts of the cd and the tape transport is worrn out and results in non action. Since there is no drive the cd mechanism nor your tape mechanism will work. If you have a help around ask them to open the top cover, remove the tray and look inside for the loading motor of the CD. replace and keep the Cd section out. by removing the connecting corrds very carrefully. ZThe tape deck mechanism is within and you will see the belt worn out. The front panel and the deck assembly can be taken out and the belts can be replaced. Attempt to do the job only if you are familiar with electronics other wise get help from a good reputed service shop to replace the motors. However this is not a expensive work but must involve great caution not to damage any parts with inexperience. I hope you understand and find this helpful. Pune is a great place and if you look around find a good sincere technician to help . Good day

Sherwood 460 equalizer hook up

Connect the EQ to the Sherwood as if it were a tape deck: EQ's outs connect to receiver's tape ins (play) and EQ's ins connect to receiver's tape outs (record).
Then you hook the tape deck up to the tape ins and outs on the EQ: Tape deck outs connect to EQ's tape ins (play) and tape deck ins connect to EQ's tape outs (record).
This will put the EQ in your receiver's tape loop.
The CD player should be connected to the receiver though the CD in's and out's (or if your Sherwood doesn't have a CD in/out, then use AUX or TAPE2).
To hear the EQed signal with all receiver sources (like the CD player) you'll need to engage the 'Tape Monitor' button or switch which will route the tape loop to the speakers.

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.
