Customer Question

I have a Sony CDP-CX355, which I constantly get a table error on. Is there anyway to fix this? The table just continues to spin, back and forth.

Hello, Try unplugging AC power to the unit for 60 minutes, then plug back in and power on while pressing the eject button. Let me know what happens.

 

Also, it may be possible that the lens is dirty and that not reading the discs is causing the unit to continuously search for the discs. Let me know and we can go from there.

I have unplugged it for several days, and while it doesn't have an 'eject' button, it does have an open/close button for the front door. I have powered it on, and held almost every button down during the process. It continues to spin back and forth for awhile before still telling me that there is a table error.

I will opt out and open the question to other experts.

Hi,
Can I help you to get it fixed?
Thanks.
Customer: replied 5 years ago.
If you think you are able to help me get it fixed, by all means please do.
Expert:  Shahid_Sony replied 5 years ago.
OK, this unit has few opto-coupler / sensors in disc mechanism to send movement signals to system control chip and any of opto-coupler looks defective and causing table spin constantly.
This unit has bit complicated disc mechanism and if you are handy with electronics stuff repair then take off top cover of unit and disassemble disc mechanism to take out table, 4 sensors are located on T-Sensor board under that table and I believe any of them is bad.
You should have related service manual copy that will help you in disassemble process as it has exploded views for that.
Hope these info will help.
Thanks.

I've removed the T-Sensor board from the unit. None of the 4 sensors on the board look defective, that being said, I'm waiting for a friend to return my multi-meter so that I can run a few more tests on the sensors.
Expert:  Shahid_Sony replied 5 years ago.
If you get pulse from sensors on that board then it is fine. Below are PCB and Schematics images of T Sensor board that will help to test it properly. I would again recommend to have service manual copy of unit.
