Looking for schematic...preferably a free download for the JVC TD-W354 dual cassette deck. One of the wires came off of one of the PLAY motors and shorted and now PLAY does not work on either deck. Hopefully I just popped a diode somewhere but without a schematic I am dead in the water. Help!
Hi,
this is a service manual for you download-able for free.
Good luck!

It might be a model that has a special IC that allows the door to open and close.
You'll need to take the case off.
try hifiengine.com...that site may have the service manual.

IF it is a deck with " soft touch " controls, that is, you arent using the old press hard down " piano key" style, but NOT a pure touch switch activation, then chances are either the drive belt has slipped, the belt broke, or the motor died. If this is the case ( soft touch = yes ), then unplug the unit, pop the cover off. You should be able to see the mechanism. When you view the mechanism from the front ( the side you normally see when using the deck ), the shiny little silver post that pulls the tape through during normal play will turn counter colckwise ( the shiny post runs against a rubber wheel ( the pinch roller )). What you should try is , with the unit unplugged and the cover off, if you can get your fingers to the deck in question, find the flywheel, should be a larger disk with a belt around it. Carefully spin the flywheel with your finger so that it turns counter clockwise, if you were looking from the front of the unit. This should cycle the deck through its cycle until you hear a click. Try to open the door. If the door doesnt open, press the stop button WHILE turning the flywheel again. This should drop the head assy and disengage the door lock mechanism. Remember, make sure the deck is unplugged, and BE GENTLE. you may feel a little resistance as you turn the flywheel. A little is OK, just be careful. If the flywheel comes to a hard stop when you are turning it, then something is jammed and you need to take it to a repair shop. Good luck...Rob. In the future, please specify a make and model so we can better help you . Thanks !!!

Ahh, Another Dual cassette deck. These are typically not worth a repair charge. I went looking for a service manual but Hi Fi Engine did not have one but they had a Owners Manual. Any unit that has a specification as to wow and flutter starting new at .18% was never made to be a long lasting deck of any quality. I don't like to be negative about people equipment but you might be better off getting a better deck from the start. If you think it is worth the repair, then send it to someone but I don't think you will want to sink $100 into a unit like this.
I am not saying it is unrepairable but that with what you come out in the end you could have made a better choice for a deck to buy.
It is probably a bad solder joint or bad capacitor on the circuit board.
I am in Chicago and would look at it for you if you want.
