CASSETTE TAPE WON'T STAY INSIDE ALPINE TDA-7547 HEAD UNIT ?
Everything works perfect on the unit, except when you push a cassette tape into it, it won't stay inside?, and just comes back out?, it supposed to click into place once its pushed into the tape slot opening, and it locks into place and is secured.
i opened the head unit to look around inside, and my friend noticed that theres a cylinder thing on the left side, like a motor, and it turns a plastic gear, which meets another smaller plastic gear, which operates the mechanism that pulls the cassette tape into the player, and gets locked into place, he was turning the gear with his finger and watched and saw it pull the tape into it, so maybe that part or cylinder motor is bad and i need to get replacment ?, or maybe the gear is'nt turning good enough and freely ?

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.
the tape coming back out and unravels the tape means the loading mechanism is the problem----when a tape goes in it loads the tape down, then it pulls the tape out of the cassette and puts it up against the drum with the video heads-----many of these are belt driven and a bad belt or belts will cause this----it is called the loading and or transport mechanism.......when it fails the arms come back but the tape does not get rewound back into the cassette so it mangles it when the cassette door on the tape closes----most likely a belt or the drive idler which also rewinds and fast forwards the tape.
Cassette tape machines will occasional require maintenance after a certain period of usage. First open the cassette door and remove the tape and any broken tape remaining inside. Some models allow you to remove the cassette door allowing you to have better access to clean the unit. Next you will need to clean the capstan with alcohol and a Q-tip. The capstan is the metal post which the rubber wheel (pinch roller) pushes against to drive the tape across the tape head. Basically clean all the shiny metal parts including the tape head. Some of the tape residue may be difficult to clean, I use Tricloroetilene which has been regulated by the government, but you may try a product called Goof Off to clean the difficult parts, but it could eat the plastic and rubber parts so be careful. Next use a rubber cleaner on the pinch roller so you do not dry the rubber out, or it will become useless. The other problem is the cassette may be driven by a motor and belts. The belts may need to be replaced and the pulleys cleaned. For this you will need to disassemble the unit to access the belts but the cleaning of the pinch roller and capstan may fix your problem, if not you need to open it up to replace the main belt.
Turn the unit off and hit the back of the camera twice near the battery compartment with the palm of your hand. Sounds crazy but it worked with my camcorder Sony DCR-TRV480. Problem started when I used 8MM Head Cleaner. I think the roller got stuck inside camcorder. The trouble code came up C:31:22. Hope this helps.
Have you taken a look at the edge of the tape? tracks 1 and 2 on a cassette are usually next to the edge and you may have a bad batch of tapes that have the edge damaged.
Another possible but not a likley problem might be the tape is out of spec. for the width, and your heads MAY have a little wear from use, and are trying to act like tape guides. If the tape is slightly wider than the grove worn in the head, the tape would be lifted at the edge and not make contact to the head.
It is not electronic as you have diagnosed this with other tapes.
Give it a try and see!
