I have a Panasonic DVD Player of similar vintage using the very same DVD transport: even though back in its days it was quite a high-end model (it reads DVD-Audio, the loser in the battle against SACD) the DVD/CD transport is very flimsy and cheap looking. To save one motor, the sled motor also acts as tray motor and it is pretty noisy (rattling sound which screams cheap). There is a very important adjustment to ensure the discs is rotating perfectly flat and you have to carefully adjust three fine threaded screws to minimise jitter and errors (shown in a service menu). The fine threaded screws are actually screwed into plastic and hence after few adjustments there is a high change to strip the plastic rendering the player inoperable. The spindle motor sits well below the disc spindle with a very long stem thus increasing wear on the bearings. Mine still works fine, but i keep it mostly as an DVD-audio player, not my "everyday" DVD player.
Does it work better with stamped, factory made movie discs? I've got some burned data dvd discs which vibrate, probably somehow unbalanced, but most of them spin smoothly. Worst discs make the whole laptop vibrate so much I can feel it on my hands, but so far they still work, but probably cause premature wear to the spindle motor. Hard drive may not like that kind of vibration either. Recently found MacGyver season 6 dvd box from local flea market for 6 Euros and have been watching it with my dvd player from 2004. Have watched 3 discs now, no problems, I've watched the whole disc, usually 4 episodes at once. Quite enjoyable, haven't watched the Season 6 episodes for a while. Still 3 more discs to go, in fact I'll go watching disc 4 right now. I'm still missing MacGyver seasons 4 and 5, hope to find them at some point to complete the collection.
I have an idea I’m sure will work. Wack some blu-tac on the caddy and give it a disc balance. Job done. Actually on second thoughts you’d have to hope the blu-tac ends up in the same spot everytime. It’s toast.
My computer dvd drive never opens on first attempt, acts like it's jammed and recloses. Then when i press eject again, opens fine. Does this every time
The porn disc or designed to stick like that so you will have to bring the machine for service then they know your watching porn eigher that or have to get rid of the player and by another one 🙂 just kidding. ….
Clamp was stuck on the disc because it didn't use a felt ring for damping but a non slipping rubber coating and the disc remained inside the unit for a long time. Happened to me on audio units and I believe it can happen on DVD drives as well.
As I still cling to my SGS 9 one thing that has proven itself to be very useful for diagnostics is the slow-mo function… It can save me tiresome diagnostics just by showing what happens in the mechanism at a speed I can track with my eyes, no zoom but the resolution is clear enough.
You ever worked on the JVC GZ-HD7U? I picked one up for free, and I suspect the power regulator board that controls battery charging and voltage regulation is the issue, as the camera does not display any lights with a known good battery and known good wall charger. Upon insert, the wall adapter will draw about 4 watts for a second, then go back to 0.1w. Would love to get the camera working. Shows no signs of water damage on the inside or outside, I hit all the ribbon cables with de-oxit.
I used to use vhs hifi for just music a lot of smart radio stations did that for the excellent quality and long play time and use tapes that they could find everywhere and buy cheap …..
Hmm maybe if you add a few drops of 3 in 1 motor oil on the bearings since it's old, should be able to open that little motor. Who knows they make it cheap and may have bushings in that motor. I remember fixing a portable cd player that the pickup motor wasn't working too well and just added a bit of oil and plugged it to a power source to make it go up/down and voila fixed as new, still works today. Hey for 2$ why not just try it who knows. 😊
Oh my gosh gross! I don't even want to think what was on that disc! if someone would have hooked that up to a TV say a young teen and pushed play he would get a surprise! Boy thank god that didn't happen!
Hi Dave, what the spare gear is for is to work the mechanism, you glue it on to end of a suitable sized screwdriver and there should be a hole on the outside bottom of the unit. It fits in there and can be used to work the mechanism back and forth, eject the disc tray and such. I used to work on these units for Panasonic in thier factory service center.
I had a similar player that wouldn't open due to a bad capacitor, and another one where the rubber on the spindle clamp perished and became super sticky, cleaned off and good as new
Yes I like the open reel I used the hiding in VHS at home and it was always good on eigher slow play or extended play I'am sure your right on all of it but I thought They used them for pre edited programming on radio but I agree with you even at the slow speeds the open reels were really decent I still got just a couple and I can't let them go … They have set so long their is no telling what they would need to bring them back up …
I remember the predecessor to that generation of Panasonic DVD player you're working on.
They used a brushless spindle motor but a single wave laser pickup that wasn't very robust. I remember problems with failing pickups in models like the DVD-A110. Panasonic had to do a lot of warranty work on those machines for dissatisfied customers. Things did get a little better with this design with machines like the DVD-A120 and the DVD-RV30, though you still had a single-wave pickup that kept you from being able to read CD-Rs.
And then you had players like this DVD-RP56 and the DVD-RV31. These machines used a decently reliable dual-wave laser pickup that could read CD-Rs as well as other discs, but then Panasonic cut costs elsewhere and used a brushed motor for the spindle. You had to love the motor controller IC failures that tended to happen with these things, too.
And what makes this a shame is that the Panasonic players generally had excellent MPEG decoders with great video quality … which do you no good when the player can't read discs reliably because the laser burns out or the player can't spin up the disc to the needed speed.
The only complement I can pay to a Panasonic player of that age … was that they were better than Samsung-made players of the same age, which isn't saying much.
I went with Sony for DVD players … but even they had their reliability quirks with some models.
But, I got a kick out of my friend's reaction with my DVP-S360 (which is long gone). He had some Philips player (Funai OEM) which he did enjoy but it took FOREVER to load a disc. Then he visits me at my place and I load up a DVD on my Sony and it almost instantly loads. He was rather envious of that…
instead of one of those fancy Yamaha CD players, I bought an old blu-ray player with RCA jacks at an estate sale for $10. The CD-R playback is always hit and miss on these.
Hey Dave, in this case why not show us how to replace that particular spindle motor. Now I know you said you weren't sure if you have a replacement on hand but just for once show us how it's done. Find the motor or if you can't order one for the sake educating us. That's not a bad investment. They can't be all that expensive…it's just a tiny motor.
Jammed by porn , sad destiny 😔
You paid 2 dollars too much😂

I have 20+ year old MP-3 discs on CD-Rs that still play fine.

I guess you are starting to see it all!!!!!!😅😅😅😅 Unbelievable!!!!!
Something sticky? P?rn? I think we ALL know what the sticky stuff was! 😆
I have that machine,2001 model Only dvd player I ever bought new $200.00! Excellent machine!😊
That machine is picky when it comes to cds!
Sometimes you have to clean disc with rubbing alcohol!!! It doesn't skip,but it is picky!!!!!!
The porn disc or designed to stick like that so you will have to bring the machine for service then they know your watching porn eigher that or have to get rid of the player and by another one 🙂 just kidding. ….

I look forward to seeing the update if there is one.
I sometimes see them cheap at our salvation Army stores but their policy is no returns on electronics.
Go to goodwill! Always some around !!!!!
i had a problem with a technis sl-pg3 disc tray will open but no close ,,also geardriven ,took me 20minutes to find faulty zenerdiode in powersupply
somebody has fucked the dvd player this time 🤣🤣

Could you find a replacement motor from a donor DVD player that craped out!

It is a good idea to sand down the playing surface of that dirty disc just in case someone rummaged through the trash and found it.

You probably had a look for educational purposes only
I wonder why it has a sticky mechanism
the disc is dirty
its full of jism
Eeew bin the fucking thing man
Personally i wouldn't give it house room, i think they look a bit naff, but nice restore job
