Hi I got PMP3000 and all of a sudden in the program smoke came out of the unit and I unplugged the Mixer...I have given it to repair and they saying the Main power SMPS has blown out..they charging too much for that part $225...wondering where I can find that part in India or in US

Cheers!

We can't understand what you are saying... DO NOT PLUG the speaker output(s) of this unit into anything BUT speakers !!! There is a hazard if using 1/4 inch speaker cables that can fry the amp.

Di you mean this one? -> http://www.behringer.com/EN/downloads/pdf/PMP1000_P0566_M_EN.pdf

Go to Google. Copy-paste the following in the search window:

PMP1000/PMP3000/PMP5000

Select the one that should be at the top that says Owner's manual for these three PMP's.

Print yourself the manual.

If you just want the pedal to turn on/off the FX within the PMP3000, just plug a switch pedal into the jack on the top labeled "Foot Sw"'

If you are trying to insert an external FX unit, best to read the manual I have sent the link to. You may have to OK loading the PDF file as some popup blockers will require you say it is OK to download.

What happened was there was an arc between layers of the multi-layer circuit board in the HCA2400 power amp at the rear of the unit. It takes extensive labor to repair the board and $20 of parts.

If you replaced the fuse or if no lights come on, it likely took out the power supply too... that is about $30 of parts.

IF THE LIGHTS still come on, get a replacement HCA2400 module (includes heat sink) and replace it. They cost about $175 online.

I have repaired several of these, but it requires a lot of skill and time to repair the module as the burned area must be carved out and replaced with jumpers and several semiconductors have to be replaced and probably a metering resistor which is usual source of the smoke.

No, that is NOT what the problem is.

The fuse protects the power supply. The power amps have failed. The usual cause is an arc between layers of the multi-layer circuit board. The labor to repair the power amp module is extensive. I have repaired several.

You can find new amp modules and I would purchase a new one and drop into your unit. The amp module is an HCA2400.

There is probably $15 of parts blown in each side of the power amp and it takes about 6 hours to repair. One has to grind out the burned area (internal layers not necessarily visible on surface) and re-insulate and then install jumper wires to replace those taken out.

Each side of the amp will likely take out 3 switching MOSFET transistors and often a Zener diode. Sometimes a low resistance metering resistor will be fried with smoky residue underneath the board. When this happens two small surface mounted resistors will be blown open. Great care has to be taken when insulating the board damage and replacement of the blown circuit traces.

You can find HCA2400 power amp module replacements for about $175 online.

Use of the unit as an unpowered mixer is a bit dangerous as if arc re-establishes it can fry the power supply taking out two very expensive IGBT's and many other components. If the mixer still works, then your whole power supply is still OK.

The power amp blew... There is a marginal insulation in a circuit board that wipes out the rear-most power amplifier. Usually accompanied by sparks and smoke.

If the lights still come on for the effects window, then the power supply is OK and you are VERY lucky... have the unit serviced immediately.

If no lights come on now, the the power supply is toast as well. There will be about 20 components fried.

I know as I have repaired 4 of these... no fun, believe me!

I just repaired a PMP3000.

A bit of warning on these. Do not let a speaker leads get pulled while powered. They can arc out the power amp causing extensive damage.

If the fuse ever blows do NOT replace the fuse as much more damage will result. Service the unit before using.

Turn it off and leave it off till it is fixed.

There is a problem in the PMP5000 that is LIKELY in the PMP3000 as well.

The problem is arcing in the rear-most power amp near the heatsink.

When this gets bad, it will short out and fry the power supply and the amp if it persists. The arcing will trip the overcurrent sense and shut down the unit including the display until it finally goes completely.

I have repaired two of the 5000's now with identical problem. There is inadequate insulation in a multi-layer board in the rear-most power amp. The arcing occurs between the output lead of the switchers and the source lead circuit trace for the 9640 switcher transistors. The output switcher lead unfortunately is an internal circuit trace and hard to fix. Once burned, the board becomes carbonized and conductive.

NEVER run the unit without a speaker load on the unit.

There isn't anything in the power supply you cannot rebuild except the transformer.

BUT you should verify that something in the mixer didn't short out and damage the supply.

After you relace the smoked parts (likely the TOP245Y offline regulator chip is gonzo... then you use this trick to restart the unit safely:

Put a 60 Watt light bulb in series with the hot side of the input power line. I would recommend you use an ISOLATION transformer when working on the power line side of this for safety.
