I bought CEC CD3300 player from second hand and I have the following problem:
Always when I switch power on and then listen the music I hear for few minutes strange noise like crackling. After few minutes the woice becomes clean again. In case that then switch power off for few minutes and switch on again, crackling is here again.
Do you have any idea, where is the problem and how to fix it. It is posible to get plan for player?
For any help thank you very much in advance.

This could be a dry solder joint somewhere or an op.amp.playing up.
Get yourself an aerosol can of "freeze".
Remove the top cover of the player and locate the output op.amps.
When the crackling is there,spray them one at a time and see if it stops.
If it isn't them,try other areas of the PCB and try to localise it.
This technique certainly works on audio amps. etc.

...listen the music I hear for few minutes strange noise like crackling...
....from the player itself (mechanical reasons) ? Or from your speakers ?
On both channels or only by one channel ?
CEC servo and main boards comes from SANYO.
There perhaps you will find few informations.
