Hello All,

I have a two year old KORG KROME 88 that has an intermittent crashing issue.
After a period of time, without fail, the keyboard screen displays a diagonal distortion pattern and the whole keyboard freezes.
So far I have tried the following:
1. Updated OS on the keyboard from 1.03 to 1.04 - That did not help
2. I tried the repair where you hold down the EXIT and ENTER keys at startup I did this 2x. No avail. Still the same trouble after a few minutes of play.
3. I backed up the SD Card according to another members experience with a 216 error, which I did not have, but was worth the exercise. Still no resolve.

I am reasonably sure at this juncture that the trouble is in hardware not in the OS or SD Card related. Anyone else who has ever had this trouble with a resolve, I would greatly appreciate some help.
Thanks!

If its intermittent after powered-up some time means overheated hardware/bad contacts.
Most likely is the overheated lead-free balls on the bga- chips/processors, which will brittle in time loosing electric contact with the mainboard, causing the sympthoms.
After shutdown/cooling down it will working again till temperature rising to the breakdown point again.

Send to korg for repair, they most likely will just replace the whole mainboard, try making a deal for free repairing because bad hardware design/common failure etc.

If you have any computer shop that repairs graphics cards nearby , you can pull out the main board and take it to them to reflow it for you.
Most probably it will fix your problem...
There is another method which gives better results on graphic cards (reballing) but i believe this is not needed in your case as krome is not that hot when it is powered on for prolonged period of time..
