When the deck is clicking when you first power it up, reach inside and turn the capstans by hand and this should disengage the tape head assembly. The problem is the drive belts are slipping and need to be replaced. The door will not open because the head is engaged.

The unit may be damaged or may just need adjustment- only a tape deck technician will be able to answer the question after seeing the unit. To answer it remotely like this, is really an impossible task.

If you have a service manual, go to exploded view 3 and look at 31.
This is the FR idler sub assembly. Check the rubber tyre or tire, see if it has hardened. This is driven by the reel motor and flip-flops between the table reel assemblies to drive fast forward,reverse, and play take up.
Also check the reel assemblies for oil that's gone to gunge.

you can have ours if you still need one.

Your unit needs a little TLC. Let me address the likely problems/solutions:

1) Tape deck stuck - The most common problem here is that the belt has gotten slippery. This has prevented the mechanism from resetting to a known position and that is what prevents the door from opening. Hopefully when you pried it open, nothing bot broken.

2) Both tape drives run from the same motor and use different belts. The same applies to the second deck as the first. The belts are sliping and need to be replaced.

3) The CD lens is probably dirty and needs to be cleaned. The fact that the CD stops and an attempt is made to play it suggests that the optics are working enough to detect the disc. Clean the lens using a cotton swab and alcohol and that should resoplve the CD problem.

If you have not opened up these before, I would not suggest you start without someone around who has. There are 3 belts that need to be chagned for the cassette section to work. Plan on $15-$20 for the belts.

I have a sony twin cassete deck and the same thing happened to mine , it turned out to be the rubber belt inside was broken so i just bought a pack of assorted belts for $7.97 and replaced both belts .

95% of all tape deck mechanical issues are caused by the belts going bad. if they have not been changed, then goto turntableneedles.com and click on the "find my player" link it will take you to the two most commonly failed belts for your model. They are square belts. If you open it up and see flat belts then email them measurement information by threading a piece of string from around the pulleys where the flat belt is found. ONLY OPEN AND ATTEMPT THIS IF THE POWER UNPLUGGED & YOU ARE QUALIFIED OR EXPERIENCED WITH ELECTROMECHANICAL DEVICES.

my aiwa brand cassete recorder model : TP-VS485 drive belt is broken, how replaced and where I can find spare parts

I had this problem on an AD-S40. Turned out to be the drive belts, which had stretched, resulting in the fact that the motors couldn't drive the mechanism through it's various load cycles of opening/closing the captain roller, etc. as required to operate the mechanism. Stuck in mid-cycle, the doors would not open.

After removing the case cover, you can turn the belt driven wheels by hand to complete the cycle, so that you can eject. Then get new belts (several outfits sell belts based on length, on line). You don't need to do much to replace the belts -- after unlocking and getting the tape out, it was only a couple of screws to remove the mechanism, as a unit, and there is no need to fuse with the circuit boards and such. Easier than I expected.
