Had this happening once... Cam gear broke! also below the camgear there are two switches that are pushed by a plastic rods (part of the lift assy) One of those 2 could have broken making the player "confused" about being open or closed. If that's the case... not an easy fix when you're not familiar with the player mechanics. kbahr or Kurtis can explain this more technical (accurate). al these terms in English are to me btw. did you check the loading belt? Might be broken...

It's an issue with the laser pickup. I have switched the pickup and it works fine. I suspect the motor is giving problems. Has anybody ever replaced the pickup (slider) motor? It says "RF-130CH" on it, Pioneer part number is VXX2472. There seem to be different version of the RF-130CH, see here: http://www.adrirobot.it/datasheet/vari/ ... _130ch.pdf Does anybody know which one I should use?

Hello I'm a newbie in New Zealand, so not quite sure if this is the right place to Post, but here goes:
I am working on a Pioneer DVL 909, which has had very little use. The problem is that the Tray would not open, - Or close, even though the message Open or Close was on the display. The Open/Close motor is fine, as is the drive belt. I was able to carefully remove the Tray Manually, nothing is broken from what I can see.
By then Manually turning the Auto. Side Selection Assembly into the side 'B' position, I notice that the Tray Loading Motor will try to Close the tray on Power up. (The Loading Motor Runs anticlockwise).
After Replacing the tray in the machine, and loading a Laser Disc, the tray will then close properly, the Mech. will raise the disc, and the Side Selection Assembly will then turn to the side 'A' Position, so it looks as though all is well so far.
However, if You then Press 'Play', nothing else happens. - At all. I have checked the Spindle Motor and all of it's Drive Electronics, and it all measures fine. No blown fuses on the Psu Board, or anywhere else on other cards that I have been able to measure.
There is also No Response if you load a DvD the Same Way.
All of the Psu Output Voltages are within spec, and the Video Output on my display with the Blue Pioneer Logo is perfect.
(I am a Component Level electronics tech by trade, experienced with DvD and CD Tape Decks and Color TV Repair, so understand antistatic, etc).
Can anyone tell me the sequence of events that have to take place in the DVL 909 in order to Start the Spindle Motor?
Any Help would be greatfully received. -- Thanks for all.
