Sir, God bless you for this video! You helped me a lot to repair a Philips CD753 for a friend. I have a masters degree in electronics, but it was 35 years ago! Your equipment is a dream for any hardware-software Specialist. I used to write some computer drivers, so you know what is it about. I just wanted to show myself, that I can still do it. But for now, I realized, that never ever again! I do not have the eyes for this anymore. But your video made it possible! Thanks a lot and greetings from Vienna!

This takes me back I used to repair CD jukeboxes 30 odd years ago, which used the Philips swing-arm pickups, the CDM-4, rather than the sled. There were no Arduinos back then, but we had a stripped down player for testing, and a laser power meter to check the laser.

The linear sleds failed in the early days so the juke boxes skipped. We replaced scores of brand new units out on sites in NSM juke boxes for a company in Twickenham in the late 90s. A modification kit was sent out so the thousands sitting in workshops could be repaired and used, as they were brand new and £400 at the time. Also the idea that CD lasers wouldn't age like styli because no friction was rubbish. In the worst of them a feedback loop kept increasing the transmitter diode current to maintain sufficient receiver diode current in the optics until the heat killed the laser. That's what's happened here. The Philips CDM 4/36 was the best, with radial tracking. We had one on a site for ten years before it needed servicing.

It seems that a lot of pickups just get blinded by dust. Cleaning the lens is usually NOT enough. I have taken many apart and cleaned ALL the optics in a few of these (as an experiment) and they actually worked fine afterwards. Note: This is an extremely delicate job and not worth doing for a $30 pickup, but it was for science. Now, a pickup that is unobtainium, this is well worth a shot.

Hi Mark. Love your videos. So you understand the DSA Protocol now? :). LOts of good information out there. I am a jukebox repairer myself. And have done a lot of these players as well holding a little stock of CDM12, Pro and Pro2 players. I actually build and sell a complete test rig for these players, have sold all around the globe to the jukebox fraternity. Based on Arduino, but with built in display, push buttons and 5 / 9V regulators too. Just needs a set of powered speakers and a regulated 12V power adaptor or bench PSU. Wanted to show you here. But cant attach images sadly.Keep up the great videos.

Those lasers are called Philips LDGU (Laser Diode Grating Unit). The main feature is, on the main package, we have diode emitter, diode receiver, and prism. They are all terrible and cheaply made. I've to say, that diagnostic mode is amazing!

It's always the laser when there's a problem. Reminds me of my first cdrom burner from the late 1990s. I was an early adopter, and the blank disks were expensive, like $3 each. Lost every second disc. 11 months into the warranty, turned out the laser was faulty from the factory. Replacement unit worked fine for years.
@ToddSauve Жыл бұрын
We had a CD player in the mid 1980s. The laser died after a few years and the repair shop told us they could not replace it. Said it was built that way and it was cheaper to buy a new CD player. The beginning of the throwaway electronics age--which I hate!

Hello Mark.... Would you like to have a go at the laser pick up for a Pioneer P-D70 CD player. I am in Australia and coming over to England in a few weeks and could bring it with me, not the whole player though as it weighs about 10kg. I have been told that it is a hard to find 1984 model and very difficult or impossible to get the laser parts here. I have sent you an email with photos of the unit.

Your videos are usually packed with very helpful information and techniques but you fell a little flat on this one. There was the tidbit about replacing the laser but in my view the meat of the video was the Arduino board and the script you ran to assist with triggering the unit. THAT is what you should do a video on. THAT was the most interesting part of the video but you walked away from us with the secrets in tow. Please do a video on that board and the scripting software. Thank you - your friend Linus.

I noticed you put the CD upside down. Are you aware of that it is the upper side you need to be careful with and not the underside? If you get a scratch in the plastic the data is still there, but if you scratch the upper side (the reflective layer) the data is lost.
