3 cd player changer repair









An old man walked to my shop and had a CD player in his hands. He did not know what was wrong with it but he wanted it to be fixed. The moment I powered up the player, the screen came on and I could hear a strange noise coming from inside of it.

He said to fix what possible to be fixed but since no one used tapes any more; I decided to fix the CD player only.

I could see some buttons broken but that is ok; he can use the remote control to access functions on this panel. The customer was ok with that option.

I had to take the two sided plastic covers and then the top one off. The moment I took the top off, I was able to see inside the CD player.

As you can see in the photo, the try was dirty and moist and I could imagine the effect of that dirt on the CD Pick up lens.

I pulled the try out and it came out very easily. It is not always like that but it is an indication of a broken belt that controls the in and out functions.

As you can see the belt was missing and I am sure it was broken as well.

I found the rubber belt broken inside the CD player and I put it back for the photo. That was the noisy sound that I heard before. Motor was running freely.

I found the right size rubber belt put it back on and tested the CD player and just I expected, the CD was not running smoothly and the sound was breaking up. I spread some contact spray on the spinning motor and I did some cleaning on the pickup lens and the CD was once more running smoothly and the sound was great.

    I fixed a similar unit (Sony) and got a silicone rubber belt in the hope it lasts longer.

    Those older player trays are hard to get when they need to be replaced. Like new replacement laser units. And adjusting them especially on for instance a Playstation 2 is harder too because those players have more heads for gaming and separate dvd playing. The owner must be happy that you were able to fix his car cd player. And maybe his cassette tape player was fixable too?

      Albert: yes they are very hard to be replaced that is why I keep old parts in my shop and never throw them away. it was not a car CD player it was a home cd player and yes he was happy that it got fixed. the tape player was too complicated to repair especially they are a lot of parts I did not bother with it. thanks for sharing
