Vestax PMC 05 PRO MIXER master output is not working

If mixer is working properly, check the rating of the adapter versus what the unit requires. Some sites indicate this requires a 12 volt adapter rated at 1.2 amps.

I assume you swapped thee output leads as well as the inputs which you di mention, to verify you amps and cables...
The Vestax schematic I have is NOT your same model, but the companies often re-use circuitry. In the schematic I have it appears that the two channels go through two levels of NJM2068L op amps.
In these two levels there is both a master gain control. It is important to know whether the gain control varies the output level of the right, even if it is low. Also in this gain control area is a master balance pot which varies the ratio of the left and right and is CAPABLE of taking either channel to near zero output... IF you have that control check it for sure !!! The pot is a dual employing both an A taper and C taper which is a reverse of the A.
The right tool for troubleshooting this is an oscilloscope, but first an inspection looking for board cracks around the output and pot area is in order.

I'd try this company:http://www.wdgreenhill.com/ I had good service from them and I live in Canada. They are in Rochford Essex.

get a multi meter and check the power supply

This has the earmarks of a failed power adapter. If the voltage is low, everything will saturate. WARNING: You could do damage to the electronics if you try to drive high levels through the unit to compensate for low output from unit.

Check the voltage from your adapter. Check it UNDER LOAD as it may collapse when connected to the unit.

Sir,
You are suggested to buy power stabilzer because some the thing which blows the power supply is unbalance voltage. which Power stabilizer resolve . hope fully this would work.

did you try the headphone jack in the back? also is the cue fader crackling when you move it left and right? also check if the cue fader is plugged in. if none of the above, check with your warranty

probably just a cold solder joint on the power plug inside the mixer. Check with a meter, then repair(resolder) if needed.

you need a sound card with headphone out seperate from master out

Picture freezing that is the symtoms of depected DMD modules...
