Pioneer Laseractive CLD-A100

[m4a2t0t]

The disc spindle motor will not spin on this unit. The motor has 2.5v on both sides and does not change.

I have a second unit that works 100% that needed a recap. I tried the PSU before and after the recap. No change. I swapped the video board that has all of the ICs on it and it still wont spin. I injected 2.5v into CN2 (the motor connector) and the motor spun.

The pickup assembly moves back and forth. The laser appears to light up, although it doesn't look like any newer laser diode with a well defined dot in the center. I can see red light refracting off the lens and then goes away after a few seconds.

Is there some sensor im missing that tells the unit to start the motor? There are 2 sensors on page SCH-3 but I though they were just for the carriage motor. One looks like a photodiode assembly and another is the park switches.

Thanks for any help

EDIT:

I've been looking over the schematics and found some more info in the service manual. It says IC201 pin 52 is the "Spindle motor ON/OFF control signal output pin ON(RUN):H OFF(STOP):L"

The RUN line connects to PIN11 of IC606 (Spindle Servo IC). Pin11 is 0.01v. What signals do I need for this to turn on?

Re: Pioneer Laseractive CLD-A100

I dunno if anyone can help but heres some more info

First number = PIN#, Second is value from working unit, Third is broken unit. If the third number has multiple values it is initial reading, tray open, tray closed. If theres no second number then the values were the same.

IC201 was in a 64 pin eeprom holder so it was easy to swap. No change. Swapped laser as well. No change.

Re: Pioneer Laseractive CLD-A100

Does the spindle motor try to move at all? The spindle motor has a FG, check if you have a signal pulse coming from the PD line J46, pin6 if you spin the motor manually
Have you compared the park switch logic and the loading motor switch logic between the two units? switches can give problems, and the software thinks some mechanism is in the wrong position to start the motor.
