Question about Sony DVP-CX995V Multi-disc DVD Player
If disc does not spins, it will be not the fault of laser unit. There is a motor, that called 'sled motor' that spins the disc. It will start to spin disc as soon as we insert the disc, and after that the laser unit will track the disc and read it. It is a common fault that, this sled motor gets damaged. There are mainly two resons for this trouble. The fist one is the trouble with this motor itself, as i descrbed above. The second one is, the IC mistake. There will be an IC to drive both this sled motor and loading motor, which drives the disc tray in and out. One IC is used as drive for these two motors. If this IC gets damaged, or burned out, the motor will not run. Moreover, fi the loading disc is not done properly, due to a loose loading belt, after insertion of disc, the main sustem IC will not get any disc in signal from the mechanism, and won't give command to the loading motor control IC, thus no voltage will be applied to the motor.
You just do one thing first. Check the 'sled motor' first. For that you have to take the mechanism out of the unit. It will turn even with the voltage that the multimeter applies to it for reading its resistance. Take an analogue multimeter, set it to Ohms range, and touch its two leads to the motor leads, as we do to measure its resistance. It must run; and will. If not it is faulty, and sohould be repalced with similar one. It is a high speed stepper motor. Anyway; just replace it. It is good. It won't cost more. Check if the loading belt of the mechanism is loose or not. Replace it also. Do these and inform me the result by Fixya. I'm ready to assist you more. OK.
