Philips CDM1 adjustment Tutorial for CD104, 204, 304 etc 

Last week I found a cd104 in my local second hand shop. Since then I am reading about the player. I even discovered your channel! I owned more than 10 cdplayers, but this one is something special. Mine have up after 10 CDs, not reading CDs at all. But I will fix it hopefully 😊 Please continue tips and tricks about this beautiful machines!

Great video and one of my favourite albums on the platter too!

I never thought id see a "brazil" made CD 204. I live in Argentina, and i have an early production sample from 1984. Only a few were imported due to the high costs. But they are built like tanks. Mine was very abused and it wasn´t taken care of. But after changing all the philips capacitors, it came back to life. If you check the voltage regulators they say "BRASIL" on top, very cool.

This player is of a earlier generation, compaired to the cdm2 and 4 i work on on a regulair almost weekly basis. A word of warning here: You should check and service the laser power supply, and the servo systems first, before making any ajustments at all !!! In my experience as a professional audiotech, it was very seldom that laserpower needs a adjustment. Most of the time the root cause is something else. Dried out electrolitics in servo and lasersupply are the main culpritt on the cd players equipped with cdm2 and 4, and i can imagine it be the same here. The bearing adjustment however i already came across that problem in the mid 90 ties. So yes, always check that. The lightblue caps in these and later generations are all way out off spec by now, so a full service should be done. Enjoy these nice machines, and indeed, a masterclock is always a very nice upgrade.

Thank you vey much for the info, My 104 stopped to read CDs and I have no technician nearby, others are expensinve. Ill try to be delicate with the screw and first clean the lens of course.

Perfect! I had a CD104 and had chatted with you years ago. Now you've revealed what the issues were! Does the CD304 have digital out?

thank you for the vid

Hi Master! Ph. CD304 mk1. (CD104 dac/servo boards) but this has CDM-0 mech. (metal plate, brushed motor) origanal CD 75min/21track 18-20th tracks often skippings and 21st mostly not read at all....and im hearing ?the focus? give rhythmically louder noisy to end. Can its be a same problem? (for history: everything was moved: -i need to grab out all from chassis, for IEC connector installation's metal works)

Is the TDA1540 DAC better sounding than TDA1541? and by the way, this CD looks much like my old Philips CD 350

Nice info where are you located in Brazil?

People don’t have a clue. You need an oscilloscope and put cd players in service mode and adjust to spec. Done many years of repairs in cds, laserdisc and video, etc. these videos on here are a joke and don’t have a clue what they are doing. What you are doing is messing it up more to failure. What a joke.
