0x000D - Sony CDP-47 Calibration/Repair

I took a look at repairing/calibrating my Sony CDP-47 CD Player with the original service manual. So I broke out an oscilloscope and cracked it open!
The CD player behaved way better in the video than it ever had for me before. It was unusable when I first got it. I had a couple issues entirely caused by my moving too fast. The probes were set to 10x, TP=Touch Point(Test Post?), and I had some misguided notions about the root cause. In the end it all clicked for me though and it worked out.
The way the CRT scope works doesn't work well with a 60fps video. In the future I'll use a digital scope. I prefer the analog one for stuff like this but it's really not needed.

We used to repair these things. The test discs are just discs with fake scratches on them. They "annoy" the servos to allow the adjustment. Having said that, if a player started skipping it was almost always a weak lazer. Running them with copy disks (less reflective than proper ones) eventually cooked it. They are correctly adjusted from the factory so, nearly always, the cure for skipping is throwing in a new laser. Adjustment rarely necessary.

Correct!

+1 for Nine Inch Nails! I love the Ghosts album.

I'm not electronic, I know very little but I have the courage to do some things, your video is the best, didactically explaining everything, trial and error, it is very enjoyable. Here, battling with a SONY CDP-750 that jumps even with a fart, I discovered that the rubbers that hold the assy, can be a bit hard, it has springs that obviously carry X torque, it greatly improves the jump or errors from what I also deduce. there is a great mechanical factor to test. Another detail that intrigues me is to check the capacitors because these would affect everything.

The trimmer pots are factory set for a new unit with new components in good cond. Sony's QC was excellent. Make sure laser lens is clean. Gently blow it out with air can nozzle. Before adj. any trimmer pot, do mechanicals first. Check lubrication and free spin on the spindle motor and grease on transport gears and guides. Then check electro caps for ESR and leakage. Then check for cold solder joints.

Buen video. Una consulta cómo puedo calibrar el balance EF del láser sin instrumentos. Solo prueba y error? Y para qué sirve realmente el balance EF ?

I've had the exact same problem with my CDP-C545. I had no oscilloscope and the internal mechanism was completely worn out. I gave up on it and salvaged its good parts.

@Halterung01 5 лет назад

This is not a vibration issue, but also not a tracking issue. That laser is done, you should just replace the laser (or the player itself, might actually be more cost effective). The weaker the laser, the tighter the threshhold of calibration in focus and tracking in order for the player to work properly.

What are these 2 white box at 18:14? I can't find anything about what they are

@seanhornibrook 7 лет назад

The manual is just saying that it is 1V from the center "0v" point to the top and bottom of the image shown. What they are asking for is a waveform that fits that description. Not what you should have your scope set to. Yes, TP is Test Point. Never EVER touch your oscilloscope ground probe clip to a voltage again. NEVER AGAIN. Ground clip is for ground. Pointy bit is for probes. Yeah - the two probe thing. Way to work that one out. Yay learning oscilloscopes! :)

@TechTangents 7 лет назад

11:58 The manual shows that for the image they took they were set to 1V/div. 11:00 shows the other signal being 100mV from center as I state in the video. There isn't always one "ground" in a circuit. There can be separate grounds for the analog and digital components. MCUs typically want an isolated ground "island" around them as well to help eliminate noise. So before I remembered what TP meant(again, filming can really distract you) I thought that they were showing which ground you should reference to.

This maybe a good time to make sure you have manual copies of all the electronics you have and may want to have. If possible ask the makers, if still operating, to digitally scan and store on the internet. Providing they are still in business.

That wasn't a slight vibration, that was a fairly hard tap.

@billy-waynejeffcoat4828 5 лет назад

If he did that to a portable CD player I'd agree with you but a CD player 50% bigger than a vcr should easily be able to brush off that tap.

@moth.monster 6 лет назад

Skipping is an issue with all older CD players... If you want no skipping, get a newer player.

@1980sGamer 5 лет назад

Not with my Philips CD-80 it isn't. You can smack the front of it while playing a CD and it doesn't care. It uses a Philips CDM-1 MK II transport. Oh and it was made in September 1990.

@avocatdelamusique9778 5 лет назад

I remember old Sony CD portable players having some sort of anti-shock mechanism, which immensely helped. Once you disable that (it was with a switch, electronically actuated) it became so bad that even a slight bump would cause a player to skip and would take several to search for a damn track.

Suggestion to you and so many other "how to" RU-vid videos. Get your act together FIRST, then make a video that is direct and concise on how to actually accomplish the task at hand. This should be a 5 minute video.

@IvanDSM 6 лет назад

This isn't a how-to video at all, it's just him chronicling his attempt at repairing the CD player. If you expected a tutorial, you came to the wrong place.

@MostlyBuicks 6 лет назад

Okay. So it is a vanity project. I get it.

@robrocksea 4 года назад

If you think this is a How To Video, blame UTube, Google or whatever search engine that suggested it. Considering most noncommercial channels have only One person to do it All, and are editing from a live feed take. Your comment is not helpful or constructive. And how do most people learn? thru practice, learning from failure.
