The key contacts are dirty on those keys. The contacts are conductive rubber "pills" in silicone domes that are pressed onto circuit traces an a board under the keys. One can clean these using ONLY 99% isoprophyl alcohol and Q Tips, HOWEVER: the disassembly to access the contacts is NOT for the inexperienced person. Each key has TWO contacts and one makes before the other and that is how they measure key velocity. When one contact fails, then maximum velocity usually results. You best take this to a repair shop and have all key contacts cleaned. DO NOT use normal contact cleaners as that will destroy the contacts.

The operating system has gotten clobbered. It is expecting you to download the operating system via USB. Go to the Korg site and find the download for your unit and the procedure.

Please get back to me..Thanks

Hi, Provided your Korg works as normal, besides the display being blank and lit, I may have the answer. It sounds like the contacts connecting the display have somehow become dirty. This could have happened from something getting spilled on the display. To fix is easy enough if you have a little mechanical aptitude. unplug unit/take batteries out,and disassemble unit to gain access to the main circuit board where screen is located, the screen may be held in place with a tin casing either soldered to board or with prong set though the circuit board and twised on the reverse side to hold in place. After removing this there should be a little rubber strip between the screen and circuit board-this is the contact strip that you need to clean with rubbing alcohol. Clean the screen where the contact strip meets the screen. do the same on the circuit board, reassemble and you should be back in business. I hope this was useful, thanks for asking FixYa, and good luck, Prodzilla.

This is due to dirty key contacts. They are conductive rubber pills pressed onto circuit traces under the keys. There are two per key which measures the velocity and affects the loudness. Clean these ONLY with 99% isoprophyl alcohol and Q tips. Disassembly to do this is very labor intensive. One has to be very careful and if you are not adept at this sort of thing, best to take it to a service shop.

I have korg Pa800 the screen scratchen, need to replace,, I would like to know where can i get a new one and how much for it,I am in toronto ontario Canada
Thanks

you may have to dump somethings from the memory, the memory is finite and if there is no more room there is no more room. as far as I know there is no expansion memory for this keyboard

Do a factory reset. Refer to your manual or use google to find the procedure.

SOMETIMES touch screens like those on Palm Pilots and the like, get debris under the bezel edge which presses down continually and is "out of bounds" and prevents normal operation. On Palm Pilots sometimes on slides a piece of paper strip along under the edges of the bezel to clear out debris.

You want to ADJUST the display "contrast" which is described BRIEFLY on page 15 of your user manual under

COLOR TOUCHVIEW™ GRAPHICAL DISPLAY

PRESS and hold the MENU button and turn the DIAL to set the contrast...

Hopefully your display is just set at max brightness and you can adjust it.

One of the internal data for one touch has become corrupted. The best thing is to do a factory reset. Read your manual and follw the directions for a factory reset.

Find information of the procedure here:

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.

Search index of the manuals for MIDI sync clock or similar name. Usually you can turn this sync clock on or off.

Here is a link with some resources:http://www.korg01w-list.com/get-downloads/ Scroll down the page for editor/librarians. Also:http://www.soundtower.com/synth/01w.htm The soundtower page looks especially helpful.

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.

It may not be the pedals as the fault can be oriented within the set.
So I think you can open the back of the set and check for all connections to be tight , remove and refit.
If this wont solve it is not adviseable to check this higly intergrated PCB without a help. So consult the Korg service.
