R3 display problem

Once I turned on my R3 at a concert and the screens started working incorrectly. All of them display characters improperly. It's hard to see what is the information on them because of bad symbols. How can I fix it?

Too bad I would say.

It can be different reasons. You will need to open it up and check some stuff (power supplies, are connecters still seated well and so on), but that does not guarantee you that you can fix it. The interface with the main CPU may be broken for instance for some reason.

Your best option is to get it to a dealer.

Not sure about the specific displays used on the R3 but, from the image, it looks either like the "clear display" line has stopped working, or a clear display message is possibly not being sent or received, or a latch enable has got stuck. Either that, or the display addressing has gone awry.

Has any liquid been spilt on the board?

No, It was in a bag all the time. Then I came to the concert, turn it on and this appeared. No hits, no liquid or smthing like that - that's just a mystery)

dealer said it's all about the LCD screen driver. It's broken and need the replacement but they don't have such one. I don't know is there any possibility to find it?
