Toshiba SD-9200 DVD/CD Player - Repair advice needed

First, I am posting this in the Digital Formats & Music Server Forums because I hope to draw on the knowledge of those that have experience with digital equipment and may be able to point me in the right direction. If moderators feel that this belongs elsewhere, off we go. Now sweat here.

I was recently given a Toshiba SD-9200 DVD/CD player because it has a problem that the former owner got frustrated with:gigglemad and needed an excuse to upgrade to something newer, bigger and better. After searching AK and quite a few Google hits, I understand that this model is a highly regarded CD player and a pretty decent DVD player. After listening to it for the short time that I have I understand why. The problem is that after playing for anywhere from 5 minutes to 30 minutes, it will suddenly stop playing in mid-track for no apparent reason. I pulled the case off and removed the cover of the drive mechanism so that I could look around inside and clean the lens. There is nothing loose and the lens is now clean but the problem remains. I also sprayed various components with component cooler mist to see if there was a component with a thermal intermittent problem. No luck. When it stops playing, it is almost as if the laser is lost and can't find where it is supposed to be. With the outer case / cabinet removed, when it stops playing you can usually hear what sounds like the laser assembly hunting for wherever it was and where it should be now. If you press Skip to the next track it will do so and begin playing normally for a while. One might think that it is a bad disc but it does the same thing with all discs including new and old discs that play fine on other players. When it is playing, everything seems absolutely normal. There are no other symptoms or issues. I downloaded and printed a service manual but there is nothing that I see that jumps out to me. I do not have a scope and serious in depth repair is beyond my ability.

I intend to use it primarily as a CD player. The sound quality is amazing. It is unlike anything that I have owned, so far at least. Unless someone posts something that allows me to fix this thing myself I will want to have it repaired by someone that has the expertise to do so. That is why I have posted in the Digital Formats forum. I have no idea who to turn to for this type of repair work. (This very well could be another plea for some kind of a directory of repair techs but I will save that for another time and place.) If there is a member that can do it, great. If there is no member that can or wants to deal with this then I will appreciate contact information for companies that members have experience with and are comfortable with recommending.

For what it's worth, while I have been writing this post and doing a few other things, this crazy machine has been playing a Moody Blues music video for the past 60 minutes without a hitch. Go figure.:dunno: Maybe it likes the Moodies as much as I do! :music:

Any help or advice will be appreciated.

Thanks in advance.

Perhaps the laser diode is failing, and is a problem that shows up intermittently after a certain amount of play. You could make sure that all the internal connections are properly seated (most basic inspection).
 
Sd-9200

yep, GREAT unit! Had one for quite a long time and LOVED it's DVD Audio and HDCD capabilities!

I've seen recommendations in various CD posts about lubricating the units tracking surfaces (don't know off hand what to use...) but I would certainly try that in addition to the laser lense cleaning that you have already done. If that does the trick for you do yourself a favor (if you like 70's rock!) and get the DVD-A version of Deep Purple's Machine Head and let the 9200 stretch it's legs!

Good luck!
 
I've repaired a dozen 3750, 4700 and 5700 Toshiba's, all needed a new plastic gear on the spindle motor, a hairline crack will cause the symptom you describe. I find these problems by manually moving the laser on its rail, if it binds at all then a gear is probably cracked, I replace them with brass and they work fine, Dave.
 
Thanks everyone for the info. When I had the top cover off of the transport mechanism to clean the lens I did look around for something obvious but I wasn't looking for anything in particular. Now I have a target. I did clean off the rails that the lens slides on ant applied some light lubricant to them. I don't know if that helped or not but I will pay more attention this time and check for any sign of binding when I do. If I do find a cracked gear, where could I find a brass gear to replace the original?

The DVD-A version of Deep Purple's Machine Head is now on my short list. :music: Thanks! I did play Dire Straits Brothers In Arms on it and, holy crap, did it ever sound great! This would be the first "high end" CD player that I have had and I am amazed at the huge difference the it makes.

Thanks again folks!
 
I buy my gears from a hobby shop, I think they're Topflight 12T gears for remote control airplanes, Dave.
 
Thanks Dave. I will check that out.

Strangely, now this thing will play a DVD without any problems at all. Music CD's that play everywhere else are still a problem, although not as bad as before I cleaned the lens and lubricated the rails. I have noticed that the disc does not always seem to load in the proper position in that it sometimes seems to be off center and out of balance causing a lot of vibration. Ejecting and reloading the disc can correct that problem. That may be an indication of a gear problem that dgwojo mentioned.

Also, I Googled and searched around the net for information on the SD-9200 and found that the "Dampers" need to be replaced. I ordered a damper "Kit" (#T-79070496 @ $16.90 + S&H @ $9.75) from PacParts (800-421-5080, www.pacparts.com) based on what I found. There are two different pairs of dampers, one blue pair and one grey pair. Yesterday the package arrived and there was one blue damper in the box. Yikes! This little grommet is not much larger than a pencil eraser! I find it hard to believe that a set of four small rubber bushings is worth anywhere near $75 for the set. I will call them today to get the straight story. I will post a comment here with the results. By the way, I read that several other Toshiba models will benefit from the damper replacement.
 
Wobbly CD's can be caused by a failure in the spindle motors single bushing they use on the Toshiba motors, they would last forever if they had dual bushings like a computers DVD/CD drive, Toshiba motors are well know to fail and there's no replacement for them available. A problem only reading CD's can be caused by a firmware problem, Toshiba releases firmware upgrades to their authorized dealers. There was a class action lawsuit on Toshiba's with firmware issues. Toshiba DVD Player Class Action Suit Here's what the POS motor looks like, I have a dozen failed motors like this, Dave. :thumbsdn:

Hi All. If you desire to revive the sd-9200 with spindle issues, simply purchase this motor and replace broken unit. For $5.00 this player will be good to go in 30 minutes.

EBay has the replacement spindle motor too
 
I’m adding to this thread to thank dgwojo (Dave) for posting (way back in 2007) the info on replacing the pinion gear on the laser positioning motor of several Toshiba CD/DVD players, which has a habit of developing a hairline split where it fits on the spindle, and to add some info for those who pass here afterward and would benefit from some additional specifics on the replacement gear.

As posted by dgwojo, it is a 12T pinion gear that is fairly commonly used in RC planes, and therefore often available in hobby shops. I removed mine and confirmed it had 12 teeth (it is really tiny, so counting had to be done carefully), and that the spindle it sat on was 2mm dia. When I looked online for 12T gears with 2mm holes, I saw there was a range of different gears. Most common where those labeled as “.6 Module”, and a lesser number of “.4 Module”, as well as some others. To try and figure out what might be the proper one, I looked up gear formulas online, and learned that there are a lot of parameters to the configuration of gears (not just the # of teeth, but various pitch specs, half heights on the gear faces, etc.). I found relevant specifications and gear formulas, including some that give the relation between outside diameter of a gear as a function of the number of teeth and the diametrical pitch, the latter which is specific to a given Module number. This was useful because with such a small gear, the only thing I could measure accurately was the OD. With that measurement, I was able to calculate that the gear in my Toshiba (a SD-1800 DVD player in this case) should be a .4 Module gear.

After discovering this, I sent a PM to dgwojo looking for confirmation, and he graciously replied, all these years later, that the maker and model of the gear he used was a E-Flite EFLM1901, a brass gear. I found that exact gear online, and it was listed as a 12T .4 Module pinion gear with a 2mm hole, confirming that a .4 Module is the correct spec for these Toshiba players.

The gear arrived yesterday, and after slightly reaming out the hole with a 5/64 drill bit so it would achieve a press fit on the spindle (as djwojo advised I would need to do), I mounted it on the spindle and it works perfectly; no more “catching” of the laser transport as it is positioned. This gear is taller than the original, but there is plenty of room in there for it without causing any interference with other parts.

Here are a photo of the laser module with the original white plastic (nylon?) pinion gear removed from the spindle, and a photo with the brass gear installed.

I hope it's ok to add another Toshiba 9200 question to this thread.

Anybodies Googlefoo better than mine ?
I'm trying to find the 79070496 damper kit without any success...

I just bought one at Goodwill, with remote !, for $10.
It's got the intermittent vibration noise.

Thanks,
Steve

Can't help with the part but I will offer congrats. The remote is worth a lot more than you paid. It has audio direct button which cannot be selected from the front panel. This button is not present on other Toshiba DVD remotes. Great sounding unit, hope you get yours sorted.

I have a SD 9200 that won't spin a disc (disc in exactly the same position when it ejects). I am not finding any replacements for the spindle motor. It seems to have 5 wires coming out of it (white, black, blue and red and black) and has the number GP2S27C on a visible circuit board.

I sounds like you are saying there is not replacement for this spindle motor, right?

The black and red wires that seem to drive the motor seem to come out of the bottom of the motor, while the white, black and blue wires come from a circuit board under the disc. Would it be possible to replace motor and reuse the circuit board?
 
Hi. I am totally new to this forum and would appreciate some help. Have had a Toshiba 9200 dvd player for some years. Now it plays Audi but no video. According to my friend who is into electronics it seems the Encoder Board PCB- 98231230 has packed up. Any idea where I can get a replacement?
Thanks
 
Well, my time to consult the SD-9200 experts.

I bought one of these off ebay two years ago. Seller said it was never used. I got it, and indeed it didn't look like it had every come out of the box. Worked great for 2 years. But after playing today, I took a break, came back and pushed PLAY. This time, it didn't. The display just said PLAY and the time counter didn't ever come up. Put my ear down next to the drawer, and I could hear some uneven wobbling that I had not heard before.

Anybody want to talk a newbie through a repair? Might be this spindle issue referred to previously, makes sense. Not sure if there are any replacement parts any more.

Thanks!

Hold on....maybe not. After I posted this, I took it out to the garage. Took the cover off. Took the cover off the drive unit. Put a disc in so that I could see what was going on, and it played normally. Put it back together, still working. But, I'll leave this here in case anyone knows where to get replacement parts, I'm sure I'll need it eventually.

Well, the return to health lasted 4 minutes. Back to dead. :(

I ordered one of the brass spindle pieces that many people said was a failure mechanism for the SD9200. No luck there, the one I ordered did not fit. Might be able to ream it out to fit, but looking at my plastic part, it looked fine.

That was my last thought about fixing my SD9200, so I started to reassemble everything to throw it in the trash. That was when I noticed an unattached cord end hiding below the tray mechanism area. Hmm, started looking around, and found out that this cord connected to the bottom of the spinner mechanism. Tried to plug it back in, and it would just bend and not go in. Looked at the other end plugged into the control board, and saw that end had a blue plastic support attached, which gave it enough strength to push into the slot without the pins bending. I dug around the unit, and found the little blue piece for the other end lodged under the power supply case. Put some glue on it, let it dry, and then slowly and carefully tweezered that sucker back into the slot (actually rotated the cord so that the bad side would go into the control board, then I put some duct tape over it holding it down.

Turned it back on, and my SD9200 lives to play another disc! We will see how long it lasts.

Again, the return to health lasted about 4 minutes. Kept messing with that cable, would work, wouldn't work. Spent some time measuring the cable, with the help of a magnifying glass, and some online research to find another cable to replace this one. $6 shipped on ebay. OK, I'll give that a shot, but that will be the last effort.

Cable arrived today. As luck would have it, measurements were good, it fit perfectly. Put everything back together....and life is good again. Everything works normally. Several discs in, no problems. Fingers crossed, but I think I have it this time.
 
Thanks Dave. I will check that out.

Hi, do you have the measurements for the dampers? https://www.keyelco.com/userAssets/file/M65p133.pdf
