From the way you have worded the question, I would say you're in no way certified to do this. Take it to a professional.

It is located on the Power Supply PCB next to the ac line voltage plug.

You use a VERY long phillips screwdriver as there are screws in those deep wells from the back. I think it takes a #3 phillips and you want one with at least a 12 inch shaft to reach the screws. The screws are black and are Kaylon or sheet metal types with pan heads. It can be a little tricky to engage the screwdriver bit as deep as these are.

Make sure ALL screws are completely out... count them vs the number of wells... there are a lot!

Then you have to pry the back off.

You probably have issues with caps in the power supply....I would check that first...open it up and look for buldging caps and replace any that you find....

First thing to do is get a can of contact cleaner. Take off the knobs and spray it into the reostats below. Spray into all the switches and even into the sliders. Move everything back and forth - 0 to 10 (to clean them). If we're lucky, that will fix it.
Good Luck

First, unless you are a trained or self-taught audio technician, don't attempt to repair the unit yourself. Let the professionals repair it. You can damage it beyond repair if you don't know what you're doing.

Non-working channels are caused either by bad connections, bad solder joints or a dead IC op-amp.

The causes of weak channels can be more challenging to track down. I'd suspect bad connections, dirty controls or connectors.

Glenn, Does it say 'overvoltage', or simply 'voltage'? For the clearest result brother, contact Mackie - 1-800-898-3211 is their tech line - they're super cool - I just always picture the guys at Mackie sitting around reading comic books and shooting guns into the air. good luck!
