Hello everybody

I have some issues with my MPC5000, and I would like to fix it!

A few days ago the MPC was connected to the Mac through USB, and while transferring, the screen started to flicker and the MPC made a shshshshsss type of sound, and then it rebooted. I pressed the power button, and while booting up, she would reboot constantly. I opened up the MPC and I noticed a burned smell. The smell came from the PSU I believe. I removed the internal HD, because I thought it was faulty.

Since that time, the MPC is always rebooting after 10 seconds of use. The other day she wasnt even responding after I pressed the power button for like 10 times.

If she reboots, the screen is always flickering lightly, sometimes the shshshshss sound goes with it.

What could be the problem? I would like to fix it. I'm in Europe, I can't just take it in for repair in some MPC specialized repairshop. I need to order parts and fix it at my house. I've looked for bulged capacitors, but all seems okay. I can't see burn marks either... My first guess is that the power supply unit is toasted, but I would like some other views on this, before I order the part from MPC-Stuff.

Let's fix this together!

but actually... are there any fuses to check? (I doubt a fuse is blown since it still boots) maybe there was a surge or something that screwed the transformer or something... do you have a multimeter to check the psu? It sounds like the power isn't staying consistently on or something...

good plan unplugging the HDD. You dont want power cutting from that randomly cause it could get screwed up from that.

No memorycard installed.. The PSU has few burned marks on the circuit board at the back in 1 area. The black area is linked with two orange resistors. Underneath those resistors are brown spots. This area got too hot while the mpc was connected via usb to the mac earlier this week, probably. I think this was the reason it smelled burned. There's probably a good change replacing the PSU would fix it, but then I have no idea if it would come back if something on the inside, other than the PSU, is causing it to heat up this much. I think I need to investigate the main circuitboard. I need to pull it out, though. It's tricky.
