JVC TH-A25 DVD DIGITAL THEATER SYSTEM disc tray doesn't open
my DVD-player does not open the tray anymore.
-when i push the open button, the screen shows the open command. (so it is not the security lock for children).
I think the problem might be the belt around the tray motor.
- I opened the casing and accessed DVD mechanism.
But now I don't find how to get to the motor. It is as if the tray is locked (something between a gear?) and inhibiting me from accessing the motor.
I looked for a solution in the manual, but i does not give the necessary information.
I will add a picture next hour..
I got to the motor out. the motor is working as it should, I put 5V and -5V on it, and in both directions.
The problem is, that it does not get any voltage when the tray should open.
Is this a problem with an electronic component?
No one an idea how to find the reason why the motor doesn't get -5V when it should open?
If not I thought maybe I can 'solve' the problem by adding an additional button that puts -5V on the motor on conditions (button pushed AND not already open)
So, easy circuit with button and the opened/closed sensor in series.
Then my question becomes: Where do I find 5V?
I suppose there is a voltage regulator in the dvd player, any ideas how to locate it easily?
Cette question est-elle utile ?
