MPC 2000 help fixing

Hi There
I wrote some time ago about my scsi fuse blowing which i got someone to repair.
that now works but the guy who fixed it put it back together wrong.
I have loaded up a program and sequence but cannot get any sound out and the pads don't trigger.
Any ideas or tips.
I have taken the cover off and before i start tinkering are there any service manuals available
or i could just give it to the guy that usually fixes my stuff.

any thoughts

Hey dude

thanks

a quick thing to check if your pads arent responding whatsoever is the ribbon cable for the pad sensors, check if its connnected correctly there wouldve been no reason to disconnect but you never know..

Hey thanks
is that the grey cable attached to the left?
It looked connected but i did take the whole lot apart to get to the scsi fusi

Just opened it up again and check inside all the cables look like they are connected properly but still no sound or pad action.
Cannot think what it might be

Find out if the pads are working :

Turn the thing on. Go to the 'Step' programming menu. Press a pad. Does it show up? Does it say a pad has been pressed? If not, your pad sensor is bad or unplugged/loose.

If the pads are working :

Do sounds load? Can you see them on the trim screen?

Are your cables all good? No shorts?

Why wouldn't you ask the guy who fixed it to put it right. If it was non functional after he put it back together BECAUSE of something he did, he should fix it.

to ensure a cable is connected, you need to do more than look at it.

unplug the cable, replug the cable.

now you know.

firstly I broke my Zip drive and then bought a replacement. It was the wrong one and blew the scsi fuse.
I bought the fuse off the internet and begaan taking the machine apart.
I got cold feet so took it to someone they fixed the scsi fuse and put it back together.
When we turned it on there was no pads working or sound coming out.
You can still hear a signal when headphones are plugged in (hiss)
I have loaded up a sequence and samples nothing
Tried triggering the pads in the sequence screen. nothing
loaded up the samples and tried triggering from tne sample page.
When i took it apart last night i disconnected both ribbon and clear cables from the pads. reconnected it and still nothing.
I delved further but looked as if everything was plugged in properly.
so i feel i have tried out as much as i could so don't know what alse to try.

To get things straight:

You powered up the MPC. You went to the main screen(the one w/ bpm, tracks, etc...) You entered step mode. You pressed a pad on the MPC down. And you didn't see anything on the screen indicating that a pad had been pressed. Right?

If that is so, it really sounds like your pads are bad.

When you load a sample and go to the trim screen you can use one of the buttons to play the sample. Does this produce audio? No?

Well then it may be something in the audio path.

Does the guy who helped you have an oscilloscope? That would help greatly, then you could see if there is any audio being produced somewhere down the line from the O/P jacks.

Use a multimeter. Are all the chips getting power?

As always. Safety is up to you. Be careful you don't short anything(esp. yourself)

Lastly, there is nothing wrong with getting it to a tech. If it is something simple and the tech is a decent person it shouldn't cost TOO much.

The guy didn't really know what to do and wanted the Schematics.
It was there for ages so I just gave up and took it back.
I do have another guy I usuallly use but he is 200 miles away and i don't go up very often, but will for this.

If I were you I would print the service manual and the schematics for the guy you are going to take it to. That will speed things up noticeably. W/O schems it is just shooting in the dark for the most part.

I still bet, unless someone shorted something when they were in there, that something is unplugged. If you are not getting audio from the outs or the headphone out then the problem lies a bit upstream from the jacks.

Also, if you still have it open etc. TOUCH SOMETHING METAL FIRST TO DISCHARGE ANY STATIC. Then try pushing down firmly on any chips that are in sockets. I have fixed 2 pieces of gear by finding chips that have become unseated and doing this.
