a) It's an older P2K model, not the newer sound-equipped ones.
b) the OP stated the shrink wrap was white. QSI OEM decoders in the P2K or Atlas locos do NOT have any shink wrap on them at all.
c) component layout of the bared board matches the shrink wrap version I posted from Tony's which is a picture of a Soundtraxx DSD in a P2K Geep chassis.
Anyway this was settled ages ago, it's NOT QSI, and the thread was just reopened by someone who discovered this loco was allegedly his and sent to the eBay seller for custom work and was instead sold and not returned.

The heat sink is the large piece of metal in the center of the decoder. The chip is on the left of the top pic. Also The Proto 2000 SD9s came with QSI sound installed.
And this is from soundtraxx user manual.
Congratulations on the purchase of your SoundTraxx™ Tsunami™ Digital Sound Decoder™. Properly installed, your Digital Sound Decoder (DSD) will provide all the pleasures of high quality, digital onboard sound and the benefits of today’s DCC (Digital Command Control) technology. With the proper tools, basic modeling skills and common sense, equipping a locomotive with sound is not difficult. It may, however, be a new experience for you, and you will find that successive installations will go more quickly than the first. Please note that while each decoder is tested thoroughly before it is shipped, we cannot control the correctness or quality of the installation. It is imperative that you follow the directions, and never remove the protective heat shrink from the decoder; there are no adjustments or user serviceable parts and this will void your warranty.

hobo9941 They say the warranty is void if the shrinkwrap is cut or removed.

They say, SoundTraxx, a small amount of shrink can be removed to unplug the 9 pin JST connector to plug in a 9 pin to 8 pin adapter.

If you ever fall over in public, pick yourself up and say “sorry it’s been a while since I inhabited a body.” And just walk away.
Shrink wrap does not dissipate heat in any way, it contains it. The shrink wrap prevents compoents ont eh circuit board from touching the chassis of the loco, hich may be connected to a rail or the motor - in this case it connects to a rail, as the power pickup is similar to AThearns. That would instantly fry the board.
ANd if you compare my picture of the one still in shrink wrap, it IS a DSD-150, NOT QSI. The capacitor supplied with the old DSD decoders was for speaker filtering and is external, but that doesn't remove the requirement for other capacitors in the circuit to make it work, mainly the pwoer supply filtering section. Otherwise you get nasty buzzing from the motor drive and DCC signal - actually you sort of do anyway with the DSD decoders, they didn;t have high frequency motor drive. That's why the one I have acts as a sound-only decoder in a dummy B unit. No motor, no buzz. The large 'chip' is the heat sink, not a chip.
I believe Soundtraxx uses the shrinkwrap to disipate heat. They say the warranty is void if the shrinkwrap is cut or removed.
Also, the decoder looks like the QSI decoder. That large chip on the end gives it away. Soundtraxx did not have that large chip, which is upgradable. Also the Soundtraxx had a separate speaker capacitor in their early sound decoders.
To whom posted this:
This model Proto 2000 SD9 #7603 was a model "stolen" from me by the owner of DP Rail Models, then sold by him along with my two other units, for a profit on EBay, all of which was turned over to EBay, and the white collar crime unit of the FBI, which investigates internet fraud. The model was one of three sent to him in exchange for one completed, finished, weathered model, which I never received. If you go to Bing and Google, then search DP Rail models, you'll see how many were ripped off, including me. My report on my "stolen" models is also posted on the Raleigh BBB site.
Btw, this model was an older model, purchased by me at a show in Ohio, with decoder and sound already in it. I weathered it myself, not this "fraud" at DP Rail Models. The model also ran perfectly fine at shows I used it at prior to sending off to DP Rail. So whatever he did to it, he ruined it, which doesn't surprise me in the least....
Ditto, just put a layer of tape on the frame so the components and circuit board can;t come in contact with the metal. That big square of metal is a heat sink - without the shrink wrap the decoder will actually run cooler anyway.
I wouldn't worry about re-covering it with shrink wrap. Finding some that is thin enough will be a problem. Cover it with some that's too thick or over shrinking may trap heat and damage the decoder. I've cut the wrap off of plenty decoders to get just a little more room in N scale diesels. No harm has ever come. Lenz decoders come "wrap free". They warn not to cover them.
If there is a chance that some metal object may contact the decoder, place a strip of Kapton tape over the spt that may be contacted.

Got the soundtraxx to work .Finding that one of the wires on the 9 pin male plug was pulled of the metal crimp in the pin.And now everthing is working.
Have one question though?
Where can I buy that shrink wrap that they use to cover the boad with and whats it called have looked at a lot of websites and have not located any.
Thanks for all the help I received.
As can be seen in this picture from Tony's:
The dead giveaway is the square bulge of the heat sink in the middle on the 9 pin connector side. And the bulge down of the capacitors on the opposite side.
Gardenrr, you noted that they said it's DCC ready. That means that a decoder isn't installed. It might just be a sound board.
DCC equipped is what would indicate a decoder is installed.

THANKS TO ALL and the tip on photo shop and also the ID of the board.
Have already ordered one from georg at yankeedabbler and will send this one of to soundtraxx just to see if it can be fixed or not.
Nothing to lose by sending it .
White shrink wrap? Then it is a Soundtraxx DSD-150. If it was run on DC power then yes, it probably is fried. They were among the only decoders after the earliest ones that would not run on DC, the manual warns you not to put them on DC track.
It is the same person
Nothing shows up
gardenrr [ This was installed in a proto 2000 sd9 that I bought from DP Rail Models and he said it was DCC ready and he did not know it even had a dcc/sound board in it.I tried everything from default to 3 to even cutting of the white shrink wrap to see if mjaybe it had a reset switch or one that you need a wand to reset it.All i get when I turn on the power from the dcc is a little crack out of the speaker and so I tried another speaker same thing. I think that something is fried. Any help greatly appericated.

Sounds like the same Perry that was the subject of an earlier post.

Gardenrr.
Can you put it on a program track and read CV8? Old Soundtraxx decoders would not run on DC. That does not mean it is fried. Try reading CVs on the program track. CV8 is the manufacture ID.

I pray every day I break even, Cause I can really use the money!
I started with nothing and still have most of it left!
Also chances are that the decoder did not fry running it on DC. Most DCC decoders are dual mode and will run on DC or DCC.
As randy noted, post a pic if you have one. You can also sometimes find the manufacturer on the botom of the loco.
Do you by any chance have a link to the EBAY sale? Sometimes the info is there.
You need to get some free photo hosting from a site like Photobucket. Upload the picture there, and then you can use the URL provided to paste into the photo link here. Under each picture you upload to Photobucket it will show you the URL to link other people to it.
Does it not respond at all? Try address 3, or else the cab number of the loco. Those are the two most logical possible addresses for it to have.
Just bought this engine from ebay and the seller did not know that it had a dcc decoder with sound in it and tested it before selling it only thing is he tested it on DC and I belive he fried the board.
Would like to see if this could be fixed but no idea of the Manufacture.
No marking on it just had white shrink wrap around it and was made in 6/24/99.
I have pictures but now way of putting them on here or I do not know how yet.
