Need Help in repairing a Sony CDP CX-350 Mega Storage CD unit

[DKasey563]

My 300 CD player makes a loud hum when powered up. The mechanisms are all frozen and a message appears on the screen saying "Table Error". I opened it up and cleaned carefully, but all I found was a disconnect wire at the front of the unit. Any suggestions? Thanks..

What happens when you reconnect the wire?
Do you have access to an oscilloscope to check the power supply voltages for signs of excessive ripple?

Sir DKasey563 . . . . .

You say . . .

1 . . .CD player makes a loud hum when powered up.
2 . . . opened it up and cleaned carefully
3 . . . but all I found was a disconnect wire at the front of the unit.

I say now. . .
1 & 2 . . . Would / could that sound be coming from the audio / speaker, possibly relating to minimal / marginal power supply filtering
OR
Could that relate to a the sound of a motor continually running . . .
BECAUSE of a broken / str e e e e e e e tched / liquified belt.. . of which . . . . two are being used in that unit.
Therefore no mechanical action for completion of its functional cycle, such that the motor will then turn off.
3 . . .Why should it be normal for that unit to have a loose "war" / or / disconnected plug ? Identify that area . . . .

More finite details now . . . . .please . . . .

I've had such a frightfull day so far, that I think I'll just put an "Out of Order "
sticker on my forehead and just call it a day.
