Follow-up video: Finding the fault in the Technics SL-PG400A CD Player kzread.info/dash/bejne/h2um2ruDidKzdqQ.html

many thanks, it was a bit advanced for me and fortunately for my needs, but did give me the confidence to open up my Technics CD player bought in the 1990s and clean the lens so that it now plays perfectly again.

I have the sl-222 model that started doing the same thing until it finally stop reading the CDs, i recently replaced it with the same model i found in ebay, thanks for the video now I know where to look for the problem.

Most people who deal with equipment like this know that Philips mechanical and digital systems were among the most used by many other brands that manufacture this type of equipment. The mechanical system use by this Technics (as you know) is the famous CDM-4/19 from Philips, used by dozens of models from a wide variety of brands (even by ROTEL in some models). Thanks for the video

The whole CD player transport and servo is Philips made and there will be at least one of those terrible blue axial cap ... I once fixed a PG520 which would randomly reject any disc just by replacing one such cap: It measured fine, but the player started working perfectly after fitting a new cap. Also note that in the CDM4 the laser output is adjusted based on what the Pickup PhotoDiode reads back and that means it fully compensates for any dirt in the optical path between the laser output, the disc the prism and the PD's array. I repaired many CD players with CD4/19 and none of those had a dead laser.

It's good to know that these problems may be caused by dead capacitors, I will make sure to check the next time I have problems with a CD player based on the CDM4 mechanism. I don't think I have ever had any problems with CDM4 mechanisms, except for the ones in the four Technics SL-PG series CD players I have had over the years...

Dr Cassette I have been repair Cd players since they first came out in the 80s professionally and my shop was authorized service center for Panasonic and Technics and you are correct Phillips made the CD unit for them and I repaired a lot these when they were almost new .

These Philips CDM 4/19 CD drives are very reliable and most of them can play CD-RW as well. But like some already mentioned the capacitors on the servo board (labeled 2501, 2502, 2503) fail very often. I only replaced the 2501 and my Technics SL-PG400A now works flawless. But I prefer the Sony KSS-xxx based CD players because they give you more options to tweak the laser, focus and tracking settings for faster performance and better error correction.

I know I'm late but I've been having the same issue, I had to use a 50v capacitor instead of 25, but after tweaking the laser a bit the disk inside stops spinning after 2 seconds but the display still shows zeroes everywhere and nothing works... Does it have to be exactly 25 volts in order to work? EDIT: I tried to play again with the laser and focus a bit, it seemed it started working again at first, just a little skippy on some tracks but it was playing, then as soon as I started playing another normal CD the hard-knocking issue was back and it was struggling reading. I am considering to throw it away as well because I don't know what else to do and I've been reading that particular Philips mechanism has a very bad reputation (now I know why)

walkthrough - two capacitors under the tray: kzread.info/dash/bejne/aZiHyaqbftvKg9Y.html

I have this same exact player I got in 1992. I havent used it in 20 years, I wonder if it still works? 🤔🤔

I have a Phillips CD player with a similar mechanism that my parents bought in the late 80’s. We had many years of use out of it, nowadays it still kinda sorta works but it produces a kind of digital ticking sound, as if the laser can’t track the disc properly. It’s a fault my dad could never fix. I doubt if it is fixable, everything else seems fine. I still keep it around for nostalgic display purposes as it was our first CD player. Nowadays I use a DVD player to play my audio CD’s.

Looks to be a high-hours unit. And somewhat unusual to see such a dim VFD as the usual habit is to play a few CD's and then power down, so it's either seen a lot of use over the years or it's been left powered up for long periods. Either way, it's had a good innings!

My 1987 DENON DCD-900 CD player, that still looks as good as new to this day, and was in use yesterday, simply required about 6 drops of oil, and all was well again. That oil had the optical sensor back to being able to be on the move across the CD once again, just as it should have been.

Did someone know where i can find a service manual or a part list for this SL PG400a CD -Player? Btw. great video!

Randomly adjusting the laser current is not a good idea. You need to look at the eye pattern. Good that you checked out the manual 😜 check caps on the servo panel.

I was hoping that just a small turn of the laser current adjustment would be enough. It only turned into random adjusting when a small turn didn't do anything... The CD player has been scrapped, but the mechanism with servo board has been put into storage for parts. I will make a note to check the capacitors before using that assembly.

The MASH font is not an indication of Philips made components as it was also featured on the later Bosch made Technics and Panasonic players that had the Sony-type laser.

I used to repair this kind of device adjusting two small screws that can be found right under the assemblage that holds the laser len. A small rotation of these screws could return the device to work in about 50 percent of the cases. I

I have tried the same steps as you, up to before the oscilloscope on a VERY similar model of that family, also to no avail... Pity because these were considered good quality cd-players once. I will try again in the future, the player is safely packed and stored at my parents house and I very recently moved my old oscilloscope there, so when I have time I may take another crack at it. However, from reading on the net, these had the rather early mechanisms and laser diodes that proved less reliable over the long run, so I am not holding too much hope.

It's funny. I seem to see the obvious issue with the unit that you and all that have watched so far have missed. The laser units with cd players are generally very reliable. But the motors that spin the disc and move the laser head are not. Not to mention the age of the lubricant on these parts. I can see the disc speeds up and slows down when you were adjusting the laser unit. The best thing to do would be to live the spin motor bearings and clean and re lube the laser head motor track. I bet this would make things unit work like new. The last 5 units I fixed had the same issue and it always overlooked. CD players need to spin at a very specific RPM to function. Also make sure the transport mech is also well lubed.

@Si1983h

This, and also look for any failing electrolytic caps around the servo circuitry and on the power rails to the servo circuitry, voltage ripple there would play havoc. Generally, if a laser is failing, it’ll skip/mistrack until it can no longer maintain focus at all, at which point it won’t spin the disc up because it can’t detect a disc there. The spindle motor doesn’t turn when there isn’t a disc present, so if it does spin, the optical sensor is detecting a focussed laser beam. It really amazes me how many people automatically assume that all CD reading issues are down to a failing/failed laser, quite often, it isn’t the case, especially on these early Philips mechanisms, and mechanisms such as the Sony BU-1, KSS-151 etc, they were/are incredibly reliable.

My first guess would be a dead laser. Service manual - parts number table - CD pickup model. The pickups for late 90s are still available from China

I have a Technics SA-CH455 with a dim VFD display. The CD player's display is perfect yet, but the tuner display and EQ display, not so much. I found a section of the PC board was burned, so I tested and subsequently replaced two of the resistors in that area, but still no joy. NO ONE has any ideas of where to go next with this thing. In fact, my local repair shop couldn't even identify the ohm rating of one of the resistors! Any thoughts? BTW, your channel is my new "binge watch" channel! 😊

@DrCassette

2 жыл бұрын

I would suggest testing all voltages the display needs to work. Heater voltage and the high voltage fed to the display driver circuit. If the voltages are fine, the display itself may be at fault. Starting in the 90s, the quality of these VFDs became more and more random. Some still look like new, others go dim. In later years, Technics' parent company Matsushita (Panasonic) was known to use bad VFDs.

I have a Technics SL-P202A Recently didn't want to spin. If i give it a spin by hand it starts up. Motor seems weak i tried adjusting laser pots but no difference, needs a hand spin up. Wondering if motor os old or perhaps more likely power supply is weak. One guy fixed a similar issue by putting in a lower value resistor but this was on a slightly newer model.

To be honest I've never really rated the CDM4 series, I've had a few dead ones. Changing the blue capacitor on the servo board can help but generally I've found that the digital output from them is very poor with a lot of noise and dropout. That says to me that the laser might be reliable but it is constantly mistracking, relying on oversampling and correction to sort the errors out. The key advantage of the linear Japanese mechs was always that the laser was an easy and cheap swap out when it did fail. The Philips, much less so. Try getting a replacement for one of the less common variants like the CDM4/25 for example.

My Technics SL-PG520A had same problem. I noticed that the laser potentiometer had a bad soldering. Probably somebody has tried to adjust it by too rough manner. My player has only one pot. After fixing the soldering, I was able to tweekie it by adjusting the potentiometer very very s l o w l y ! My player has two HOLES in the bottom where it was easy to adjust with PH00 screwdriver. I also taped the dangerous fuse with thick clear tape. This sadly is Philips style whereas Japanese equipments usually have very well shielded mains components.
