I suspect you have aa pwer supply problem that is supplying low voltage to the unit. The display will light at low voltage but circuitry will not run when voltage is low.

Can somebody post the PA800 Diagnostic Menu Command


The details are highly confidential and have only ever been released to engineers under Non Disclosure Agreements, who work closely with Korg in the design process. If anyone tries to tell people about it on the forum then a breach of an NDA has occurred and whoever did it could be sued by Korg. The person posting those details could have their account on the forum suspended.

Please understand that there are very good reasons why Korg want to keep those details confidential. The functions were designed for use in the factory when the keyboards are manufactured. Two of the functions can completely wipe the internal SSD and the boot EPROM rendering the complete keyboard unusable. One of the circuit boards would have to be returned to a factory for the chips to be re-initialized using specialist hardware plugged directly into the CPU board. The necessary hardware to re-initialize the SSD and Boot EPROM is not even available to Korg service centers.

If you are someone who has discovered the way to access the system diagnostic menus, then there is a high risk you will completely trash your Pa2x/ Pa800 etc, turning it into a "brick" that will no longer be capable of reloading the OS or factory data. Korg representatives have said to us several times that damage caused in this way is NOT covered by warranty. If two of the functions in the system diagnostics menus are used, then to get the keyboard working again, service centers will have to replace the complete "main board". This is the board which contains the SSD and boot ROM chips. You are looking at a repair cost of over $800 plus shipping.

Have you tried touching the screen with a pen, or stylus. Or even your finger nail? My KORG does not work well with fingertips, needs something harder.

I got korg pa800 my touch screen is lighting up but nothing is appearing on it


There is a contrast control. Look for it in your user manual. On page 14...bullet #25... You press the menu button and hold it and rotate the dial to adjust the contrast.

Whwn I turn on my PA800 it says Warning OTP Corrupted press media to continue!When I press media it starts to read and the instrument is working as usualy!?


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.

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.

MY korkg PA800 doesnt load the opperating system and it wont let me reformat it, all i get on startup is a clear screen and nothing else happens


I don't know if your keyboard has a lithium battery for memory backup but that used to be a symptom of battery failure in other synths. Here is a link to a forum that discusses all the various problems:http://www.korgforums.com/forum/phpBB2/viewtopic.php?t=38399 Lots of reading buts lots of links and help.
