SOURCE: I can`t load the OS in my KORG PA 80. No way to make it work. I think than the problem is the mother board.

Have you tried it with batteries? Are you sure the power supply is working correctly? It should not need the OS to operate as a keyboard disconnected from the computer.

The cable connection is just a MIDI cable that uses opto-isolators so the 2 items are electrically isolated from each other. The software driver for the Korg should load without problem. The Korg program itself may be looking for inputs that are not there when the keyboard is off and the program itself reaches a stop command.

If the PA80 will not work on just the power supply- the power supply can be the fault- it has an internal fuse. Finding a similar supply with the same coaxial plug wired the same polarity is the way to test it if the battery option is not available.

Older peavy 4 string bass with batteries need wiring shematics


I think posting the wiring schematics is not legal. If it just does not work anymore you could try and look if the battery clip is oxidized and try to clean it.

Hi my keyboard problem some time the screen turn on normaly and some time not i have to turn it of again how can i fix it tnx


It is possible that there iis a compnent failure in teh POR (Power-on-reset) circuit. This is NOT DIY unless you are adept at electronics. I do NOT have the shematic for this keyboard. I looked at the schematic for a PA500 which MAY be similar and it has a touch screen. SOMETIMES dirt gets under the edge of a touch screens and confuses the processor with a false input. If yours fits this scenariom you might try running a piece of copy paper under the edge where the case hits the LCD screen.
