LaserActive:Pioneer Laseractive CLD-A100 Various Issues and Solutions
The biasing network design of the Laseractive makes it prone to major damage should one of it's voltage rails become absent. This page details various failures and fixes known for the Laseractive player to assist others in their repair efforts.
No display or dim display
The most likely root cause of dim/no display is loss of the +5V rail, likely due to a PAC with shorted voltage rails. Replace ICP's on the power supply and bench test the power supply before reapplying power.
Optical Pickup Emits Smoke After Player Turned on
If the either the +14 or -14V voltage rail is missing, this will cause a voltage imbalance on the focus/tracking amplifier and cause the pickup to emit smoke. Ensure that the +/- 14V rail ICP's are replaced on the Power Supply, as well as the two ICP-N10's on FTSB. Additionally, reflow solder joints for connectors such as the ribbon connector on FTSB and the various through hole components on SYPS.
Discs spin at maximum speed, no playback
If discs will spin upon pressing play, but seem to spin at maximum speed with no playback, there is most likely an issue with the spindle motor speed sensing circuit. Ensure R111 and R110 measure 1k Ohm (+/- 5%) and that R109 is less than 1 ohm (actual value ~0.05 ohm, will show as "shorted" if checking for continuity). Additionally, check whether IC611 (4558D) on the VIDEO board is not damaged.

CD's do not spin/CD's Spin but stop after several seconds
If Laserdiscs can play but CD's cannot spin, or if CD playback is possible, but stops after several seconds, one possible root cause is a missing signal between the EFM Decoder circuitry on INTF and the Mechacon on CONT. It is recommended to reflow the solder joints for the rigid right angle connectors that on the CONT board that connect to INTF.

Laserdiscs do not spin
This is most likely due to a worn/loose carriage motor assembly belt. Replacing the belt should provide enough tension for the motor system to clamp the laserdisc, but it is also highly recommended to replace the capacitors and ICP fuses on the power supply as well.
PAC N1/N10 crashes after several seconds
If an ICP-N50 has been added but connected to the wrong voltage rail (i.e. EVER 5V instead of SW +5V), this will cause the PAC-N1/10 to crash as well as PAC-S1/10 to run at abnormally high temperatures.
