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. Additionally, the audio demodulator

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 sensor. Ensure R111 and R110 are 1k Ohm and that R109 is less than 1 ohm (actual value ~0.05 ohm, will show as "shorted" if checking for continuity). Also check IC611 (4558D) on the VIDEO board is not damaged.
CD's do not spin
If Laserdiscs can play but CD's cannot spin, one possible root cause 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 on the CONT board.
