Hi, I need your help!
I have bought recently Sony Discman D-15 from eBay as is condition seller discripped trun on power LCD dispaly on CD rotate.

I have DC power adapter 9V - 1A polarity corrected connect power supply, used very good original CD. After loading CD press play button CD rotate, track number showing 01 I heard laser trying to raed CD but failed continue some time after few turn off power. I have open check midile gear stuck as usual sony, when I order D-15 same time I have ordered gear as well so I have spare gear removed and replace. Than try again, CD starte rotate CD track number seen 01 then laser trying to read but failed to read then stop turn off power.
   I had clean lens but not solve problem. Seem this model have 5 nos electrolytic caps only, power supply have 2 caps C401 & C411

My guess you need a laser calibration to decide whether a new laser should be installed. It can read discs randomly indicates probably its still working.

Hi kaosun Thanks for replied. You may correct, when press play button display shows "01" seems laser can see TOC but not play song continually sometime! skipping songs , sometime even not read CD. I have noticed display not much bright compared to YouTube seen same players! I have 9V -1A power supply also external power supply 30V-5A.
   This weekend I will calibrate laser, can tell me exactly which Focus Boas other voltage Adjustment, I don't have Oscilloscope!
However, today I have place order to you new laser from KAOSUNCD for my Sony D-15, I have another D-25 on the way from.
Note: I have lubricate motor bearings.
Added:  When I try to connect my external power supply (30V-5A) set to 9V - when playing CD load amp keep changing 0.214 to 0.325 load not stable is this normal? Thanks

Your measured current is quite normal.
