Restored A 1996 ONKYO 6-CD Player Model DX-C330 To Working Condition
This belonged to a good friend, a regular customer and an antique collector. He told me that this was not used for a long time and when he took it up for checking, it was getting on, but no functions worked. As this was working on 120V AC, he provided me a step-down adaptor, picture of which is what you see at the last above.
Since this was the first time a CD player of this kind came to me, I got interested and opened the cover. There was no dust inside, which was a surprise to me! Probably he would have kept it wrapped in cloth while storing. In order to look at the motors and mechanism, we need to remove the loading tray first. Without removing the rear cover, removing the screws holding the extended arm from behind that holds the tray in place, and tilting it outside, we cannot see the motor mechanisms. Let us have a look at the interesting inside of this 28 year old CD player.
As you might perhaps have observed, the belts were rigid at the point where it was around the capstan of the motor and looked slacking at the rest of the places. I combed my stock of belts and replaced these three belts one by one. I also cleaned the eye unit very carefully using IPA on a fresh and clean cotton swab. Then kept the tray back, fixed the arm and applied power. The set started working very well with its round movement of the tray, eye unit coming up each time for searching the CD and its starting point.
I pressed the eject button and the tray moved out. Then pressed it again to load it. I did this a few times so that any hard grease on the wheels got loosened. I kept a CD that came with the player on one slot and used the skip button in the front and loaded it. It played very well, which I checked connecting it to my Table Top 4” CRT TV that I always use for checking DVD/CD Players. Let us have a look at the following pictures:
You can have a clear look at the belts in the last picture above, which shows how the elasticity of the belts was affected.
Mission accomplished with a hexagon shaped satisfaction gaining entry to the collection bag! (LOL)
