wrong plug

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.

If you don't know how to repair electonic devices, you should look for a local repair service. No magical way to help you to repair a broken Korg

There are a number of IC's in your synth. Traveling with it in and of itself wouldn't cause a problem, but rough handleing during travel may be. Always use a road case on your gear. That said, you'd be best to take it to a repair shop to get it sorted out correctly.

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.

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 / 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.

There is no adjustment to control the brightness in korg pa50/sd. It is hardware problem. -Is the white backlight that is too high? or -normal backlight,but words is too dim? Both of that case,can be caused by damage / change of voltage control for lcd. Perhaps there are parts that are damaged or have changed in value. Typically capacitors etc. If the backlight is too bright, then the damage is in backlight controller, may transistor or an inverter transformer. Proceed with the repairs to the experts.

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.

I had an old organ/keyboard repair man tell me 95% of his repairs were diodes over 10 years old. Everything else was switches, capacitors & transformers. Hope that helps.
