Ok I followed the steps and got the screen working again. But now the heated bed won't stop heating up as soon as I turn the printer on. Even with no print active it will heat up to 95C. And with a print in progress it will pass the bed temp of 50 and keep going higher the entire time. It's gets to 80 quick then slowly higher till I power off the whole machine.

Have you tried to "default factory"?

[Octagonman]

Now I have done the factory default and the same is true. As soon as the power is on, the bed started heating up. The temperature reads accurately as well. I don't even have to be printing anything, the bed starts heating when it boots.

Please dont use rar, I cant open it on any of my machines. And these instructions are weird tbh. What should I do with the "new ui" files?

[Lexan]

winrar is free to use for every os, so may you check that first.

whats wrong with these steps ?

[gamura]

Okay, I just managed to open the rar files... and it took me a while to realize, that you have to store them on the internal SD. Not the removable one^^.

[gamura]

Why not use zip which is free in terms of open source and suppoted out of the box on every os? Winrar is closed source and a somewhat shitty compression tool^^. I thought it would be dead since the ages of p2p filesharing.

I just got a new A30 printer but it doesn't display anything. The power LED light is showing but there is nothing on the screen. I downloaded the files here and replaced the old ones but I still have a black screen. I noticed the motor / fan also doesnt spin continuously. The fan/motor seems to start and stop each time. Are they supposed to keep spinning once plugged in or is this just a black screen problem? What advise can I get please?
Thanks

Hi, then the temperature displayed on your screen is the temperature at which the hotbed is heated? You can try unplugging the hotbed line and see how the temperature is displayed.
If the temperature still shows the heating temperature, it is a problem with the motherboard.
