Might be a case of opening up the M50 as the previous poster did and wiggle connectors and components until the sound is affected. If you have some electronics experience, it should be fairly easy to figure out which board to investigate.

Hello, You may want to reset your machine, all data and pre loaded programs, for this you must turn on your M50 press the global mode button, click on the top arrow next to (basic) select option 2, load pre-preloaded demo data, you then choose all (PCG and demo songs). press OK. Your Korg will re install all factory samples, data and settings. Once completed It will then instruct you to turn off your machine. give it a minute or so to self upgrade before turning it back on, once you turn it back on you should see updating panel notifications right and left, you should be able to use all of the sounds and combi's available for M50. that's a factory reset. I hope this helps, Have a great day.

Your best bet would be to contact Korg directly. Here is the link to their USA support page

Hello, I own a Korg M50 myself and I had the same issue, its a quality control issue at their factory but, I may have a solution for you I found at a Korg forum. the issue is with these teeny cables inside the synth. you open the rear panel and firmly press each teeny cable into the terminals again and re attach and secure them firmly just finger push them all into their teeny sockets. this should stop the freezing I tried it the synth played all night with out freezing . I hope this helps other wise the solution with the capacitors is simple you order a new mainboard but they run about 400 plus. but try my solution it may work for yours this answer comes from a korg tech, he stated 90% of this freezing issue he has encountered has been these loose teeny cabling adapters, hope this helps, Have a great day..

Well looks like you have a capacitors problem. I had this problem too and a friend soldered two new capacitors in place. You can find information on the korg forum but most important is to know where the capacitors are located

Refer to page 222 in your PA800 user manual regarding calibrating the polarity of the damper pedal. The setting in your unit MAY have gotten clobbered.
It is NOT clear if you have a PA800 or M50-88. If you have the latter, then read page 22 of your user manual where it says in certain modes the sustain can be set to affect only certain voices. Again, see if internal parmeter settings may have been clobbered to disable the sustain.
