SOURCE: yamaha s2500 dvd player
Hello, frustrated Yamaha owners.
I have destroyed two of these machines to remove my precious CD's. I did discover this today:
1. There is a fuse but it is soldered onto its circuit board.
2. There is no easy way, like using a paperclip on the old computer cd-rom drives, to release the cd/dvd tray. However, when I destroyed my second player, I noted there is a rather large piece of metallic tape on the bottom of the player to the right side of the front of the drive on the metal bottom cover plate of the machine. It is covering a slot about an inch long. If you carefully remove the tape and use, say a phillips head screwdriver, starting at the right side of the slot as you face the front of the player, you can slide a plastic bar that will free-up the tray slightly allowing one to pull the tray out and save the cd or dvd. I would do this with the player upright but hanging over the edge of a table so that the freed cd doesn't bang around against something in the process.
For what it is worth, I hope this helps.
Yamaha should be ashamed of producing a product at this price point with an issue like this. At the very least there should be a fail-safe way of removing a cd/dvd from the drive regardless of the issue with the electronics or drive mechanism.
Sounds like the power supply in the dvd player has failed. It works just well enough to turn on the led infront but as soon as you go to do anything it shuts off. This is common in cheaper dvd players. Unless you can troubleshoot electronics. Or know someone that can. Your best bet is to unplug the unit and disassemly and retrieve your dvd.
Optic Sensor MOTOR Signal Test Procedure
Turn on unit power. Do not press display keys. Use your hand to rotate the motor flywheel. Normal result:
LED 10 lights to indicate the optic sensor signal entering the drive board. The LED appears to flicker at a
low speed and remain lit at high speed.
Optic Sensor MOTOR Signal Test Results
If LED10 does not light, inspect:
1. Optic sensor signal wires and their connections; Reinsert wire ends into connectors.
2. Whether optic sensor wheel rotates in the middle of the sensor; If not, reinstall the optic sensor wheel.
3. Whether optic sensor wheel teeth are broken or bent; if so, replace the optic sensor wheel.
4. If LED2, the VCC circuit indicator, on the drive board lights and there is no optic sensor signal output
(LED10 does not light), and if optic sensor wires and connections are good, replace the optic sensor. Watch this videos tips:
