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.

After updating the firmware, you likely must do a factory reset. This is probably required so the keyboard will read and decide how much ram actually exists. At this site do the "factory reset" version:

Make sure all midi and usb settings are correct on both ends. Check cables. If all else fails try factory reset.

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.

Korg Pa800 Synthesizer i have noise on ram samples Answer i turned on my pa800 and when i play ram samples there was some noise like cracking and distortion,... (More) i turned on my pa800 and when i play ram samples there was some noise like cracking and distortion, that happened 2 or 3 times, now its normal, but i think it may hapen again??? where is the problem, somebody says it is on motherboard? or its just ram overheating? since i install 2.01 os i noticed that its kinda warm in right display corner, can u help me???

You just the device unpowered, you can try uninstalling and reinstalling the SSD Side Module to reseat the connectors to check it's not bad contacts causing the problem. Also check there aren't any bent/broken/missing contacts visible in the side module or the SSD itself.

The pa800 has a fixed amount of Ram at 64mbs and it is not physically possible to upgrade the Ram. The pa2x has a removable128mbs Module and that can be upgraded via a 256mb Module from Korg.

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.

I suggest a hard reboot / initialize. Istructions are in your manual or on the Korg website

i would send it out to the manufactures just to be in the safe side

Hi Mosh i know this problem , the nand ic on the mother board is fault, you need change the motherboard

Sounds like your keyboard screen is going bad, You need to contact Korg and order one, you can do it yourself or they have authorized repair shop around your house. Good luck
