Technical questions for the MPC2000xl and the MPC2000
By MeanGreen Tue Dec 06, 2016 11:42 pm
Hi everyone,

I've been having these exact symptoms with my 2K classic. I've replaced the R23 resistor properly by taking the whole board out etc, but this didn't seem to solve the problem, I would really appreciate some more info regards to solving this problem on the 2k classic. Sorinp, in the picture u posted u have a yellow circle around the R29, should I replace this resistor a well?
Any help would really be appreciated! before I discovered this topic I gave up on fixing it but this gave me hope again.

Kind regards.

In any case, on the MPC 2000 Classic that resistor is labelled R23 but you cannot see it from this angle... it's located exactly where Star One said it would be, and it's indeed YELLOW-PURPLE-GOLD-GOLD. That's the floppy drive to the left. Check out the pics. In the first one the M symbol (next to the Omega symbol under the number 4 on the voltmeter screen) means it's dead by the way, I just learned that today :-D The technician was very happy :lol: :lol: :lol: Hopefully I will report back with some good news...

Sorinp, I'm facing the same problem with my 2Kclassic and your help would be very appreciated. Did the guy that fixed your mpc also replace the resistor you marked with the yellow circle in the picture (R29) or just R23?.

Kind regards

Each one teach one :nod:

In this application an M would defiantly mean nothing is getting through, dead is right. But in other applications you sometimes have things with the metric prefix M for Mega, or 10^6. Of course most here won't be working with anything that requires that much resistance ^_^


So that 4.40MΩ would be 4400000Ω

She* didn't mention because there WERE complete photos showing the XL haha! I still need to fix that.. Maybe I can do that today. Won't take long to flip that cable back around and do it again (still going to use the 'cut and crush method').

I would have put (2000XL) in the title but I didn't know anything about the 2000 back then or how different they would be.

Yes! I'd love to get the pics too if possible, please. I think that I really need this resistor. :idea:

Or even if anyone could tell me which board and where its located.

The resistor is in the lower right hand side of the motherboard, the area where the ate and floppy power connector is.

Just took a pic, I believe it is labeled R1? Is this the correct resistor?

It looks a little odd to me... does mine look burned out to you?

It's kind of hard to tell because the picture is dim. Mine didn't look burnt when it was though. For the cost involved in changing it, you may as well give it at try.

I will definitely take your advice on that brother, and I'll switch it out to see if it fixes the problem... because like Lamp said, any time something smokes in the MP, it is not a good sign.

Is this the resistor that you described earlier?

Here's a better picture:

Yep. that's it. R1 resistor. I've seen crispier resistors than that.

Thats the exact resistor. I wish I knew about it before sourcing out another XL motherboard to use. A year after the fact this thread was made, then I pulled out the 'dead' motherboard, swapped out the resistor and now it's new again. I'm going to sell the motherboard for $450 so that I can have my own eBay post in the stupid gear prices thread.

Good luck either way. I really hope it's just that little resistor and not some other sh*t going on.

Got my sound back to normal via the record inputs while in the sample screen... I honestly feel so good right now. :-D

Hope you get a quick sale one that. I'm happy that you didn't lose your money after all :)
