TG/PCE Repair/Mod Discussion / Re: CD-ROM2 with stactic/cracking noise while playing audio

Crackling can be the sign of a lens requiring adjustment.
Are you testing with a real audio disc or a CDR?
Does this happen when using the CD drive by itself(not in the docking station) as well as docked?
This could also be an under power problem. What power supply are you using?
Thanks for the help. I'm using original audio CDs and have tried two lenses with the exact same result. The music plays correctly, but there's always background noise/interference. I've captured a video to show the problem:
I'm using a 9V, 2.5A TRIAD power supply.
The noise is also present when using CDROM2 independently, both through the main jack and the rear line out.
EDIT:
I've checked the power supply. CDROM2 is receiving 9.36V, and the measurements at its voltage regulator are 8.5V input (approximately; I forgot to write it down) and 5.1V output.
