Question edited for maker.
Question moved from Musical Instruments to correct category.

Running a 1/4" cable has no bearing unless you are trying to run a hundred yards of cable. Check your plugs wiring and connections to the unit. Here is the manual.

The PMH1000 is VERY close to the PMP1000 and circuitry is almost identical:

Scroll down to "Get Manual" and click on it to download... IGNORE other downlooad links. Also please read my tip about a hazard for PMP mixers regarding using SPeakon to 1/4 inch plugs for speakers. The tip of channel B is the hot... BUT the sleeve of channel A is hot and grounding it can blow channel A amp. This has class "D" switching power amps which are efficient. The power supply is a switching type that runs off the line voltage. Working on the supply requies using an isolation transformer for personal safety.

GO ONLINE AND CHECK BEHRINGER EUROPOWER EXP3000 STEREO POWER AMP. YOU MAY GET SOME HELP THERE.

If you have manual, schematic is in the back pages. If not go to Behringers' site and download PDF (I believe it's under support)

Often teh power supply fails because of other problems. Unless the board has flame damage the parts that are defective can be replaced... Getting some of the parts that are special can take time. Most of the components are available at many sources however. The SPS400 power supply can be repaired.

Here is link to schematic that should have the SPS400 as well as the rest of the PMH1000 on it.
