if your pretty sure its a crack in the circuit board from dropping or rough treatment then yes it can be repaired in less than an hour-contact a guitar repair center to see who does there electronics repairs they might take that on if asked , but if it just started to do this with out a known cause its most likely a component failure and that will take some time and knowledge to find cause and repair , on this unit that might not be feasible to do

Your best solution would be to take it to a repairman. There are too many possibilities as to the cause of the problem to guess at them online.

Hello, To record into a lap top you will need a USB mixer, your audio output from the SYNTH will go into the mixer, you use the midi USB cable from the mixer to the lap top. this will help pre amplify your synth to normal audio levels. hope this helps.

Hello I have this M50 61 key korg model, I had the same issue the fix is simple remove the back cover on the unit, carefully push in all the small cables reattach them well do it to all the small connectors these cables get lose and cause this issue, good luck let me know if that helped I fixed mines that way its been working excellent since. good luck..

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.

5VDC is absent. The 0 Ohm safe resistor is dead. Backlight is off in this case too.

Step 1: Check the setting of LOCAL CONTROL in GLOBAL mode. Go to GLOBAL mode page 1 (Figure 1-2): Move the cursor from the MASTER TUNE to LOCAL CONTROL. Setting LocalControl should be in the ON position. When the setting is OFF,set it to ON (use dial TEMPO / VALUE or DOWN / UP button). Go back to ARR or PROG mode,and play the key to check audio. Step 2:If in step 1, the sound still does not exist, then it is a hardware problems, and the possibilities are : Figure 3, the section in red shading is a block may be damaged. Figure 4 is a scheme. Parts that might be damaged in case of no-audio are: IC 2,4,5 (4570), IC9 (78L05), IC6 (PCM69AU), IC 3 (5216). Check also the transistors Q1-Q7 (This is the MUTE transistor, and this is most often the cause in case of no-audio). If you can not fix it by yourself, then leave it to the experts...

You can try a full reset (instructions in your manual) and if it's a software glitch that should fix it. If it's the switch itself, you have to disassemble the unit to get to it to try to clean it or replace it.

If you have updated your computer OS it may no longer be compatable. Other than that do a herd reset on the Korg and see if that helps.

It's more likely to be a cleanning issue. Really, it's almost as easy to replace the switches as to clean them. Parts are available on ebay for very little money.

It is power supply regulator problem. In the regulator circuit, DC 12volt from adapter is separated into +8V, -8V, +5VA, +5VD. Some causes when the unit hang /blank/ frozen is one of the existing supply voltage is drop. In general, +5V. Also check the adapter voltage, if still normal and the current is sufficient. Adapter must have DC12volt and current of at least 3 amperes. It may happen, when the adapter is measured without load, it's read normal 12v, but when loaded to turn on the keyboard, many voltage decreases (lets say,between 8-10v). This indicates that the adapter is not good and need to replace.
