TG/PCE Repair/Mod Discussion / SOLVED: Duo RX loud scratching sound when CD spins
« Last post by opticalnoise on March 22, 2024, 11:21:22 PM »When I try to put any type of CD into my Duo RX, the console can read it but I hear a loud plastic-on-plastic scratching sound. When I lift the CD mechanism out of the console and let it sit on my desk while still connected to the console, it spins silently and is essentially working perfectly. I've verified the disc and all the moving parts of the disc-reading component aren't touching anything. There are no loose wires, no capacitors or any other component that could potentially touch it, make it unbalanced or uneven, and so on.
I posted about this in a Facebook group and the suggestions were something was touching it like a bent capacitor or that the mechanism wasn't sitting correctly. I've reseated the mechanism a few times, ensuring that the foam-rubberish stands are all touching and centered on the three posts coming out of the main board. I've tried pressing gently on different corners of the drive while the disc spins to see if maybe its off-center while the case is off but this seems to only intensify the scratching noise. I also tried adjusting the 3 controls on the board, VR102 and such, all to no avail.
The only suggestion I haven't tried yet (as it sounds like it has a high possibility of causing damage) is adjusting the CD spindle height by physically pulling it upwards.
This is one of those cases where this was a device that worked for years, sat in a closet for a while, and now doesn't work. Any thoughts on how I can address this would be appreciated. I'm new to this forum so I will try to post a link to videos of what I'm seeing and hearing after this post goes up. Thanks everyone.

about to create another thread for the next issue I have that is proving just as difficult. But I wanted to keep this information here because I have seen a few cases where people have this issue and it is a damaged 5V rail and this was the same issue, but caused by the 9V rail
