I have a Denon DCP-150 I purchase new.  I haven't used it in ten years and when I tried to recently it failed to function.  The disk will turn, you can year the laser assembly moving and I have confirmed that the laser does produce a beam.  I was thinking that the capacitors were out of spec.  What do you think.  I also live in CA by the way.

Hello,
I would have a question concerning the Sony D25S. Just got one (new old stock) from ebay. While testing it (headphone line out), I realize that I could clearly hear a background noise on the left channel (especially audible at lower volume) but nothing on the right. The background noise seems to be constant, i.e. it does'nt change while cranking up the volume and becomes pratically inaudible at higher volumes. Changing headphone and CD does not make that noise disappear. The line out seem however unaffected. Any idea where it could come from and how to fix this ?
Many thanks

If the cpas leak, their electrolyte may corrode the PCB and the other components.

Therefore, the electrolyte must be cleaned, all caps should be replaced, and the circuit parameters should be readjusted.

For many years it has been used, necessary lubrication on machine are needed, including VOL.

Also, for the special structure of the PCB installation, disassemble and reassemble shoule be much careful...

Obviously, the problem is caused by earphone amplifier consisted by M51568.

 

M51569 contains a pre-amplifier after VOL and before power amplifier.

 

You can download a PDF datasheet of M51568 to check whether the L pre-amplifier outputs a noise when comparing to R channel.

 

Usually the problem will be caused by a small resistor or a SMD cap, it'll cost a little time to locate the component. If nothing found,

 

you'll have to consider the replacement of the M51568.

Hello kaosun

I fund your blogg while searching for laserunit kss221A.

I just bought an sony D-35 ( serialno.142365) portable CD player with remote RM-DM1.It has an optical output,were i like to connect my muse DAC.

The seller wrote,that is has horizontl. tracking problems-but it is not reading the Cd;s at all.

Laserunit is working- can see the red beam.

Unfortunaly i have no service manual-but i found one new SF89 laser unit in polen and bought it for 50 $.

I think ,that i need some advice for disconnection and removing the PCB.

My profession is wireless electronic specialist and i do repairments on old hifi-gear for years,but avoid the little stuff because i have no smd-equipment for service.

Can you help ?

Many thanks and best regards
