thanks for your response,
I got the same screen the first time I switched it on too. But, like you said, it disappeared within a few seconds and worked normally.
The only thing I can think that I may have done wrong was to switch off the mains supply before switching off the device. I've checked the power supply, it seems alright. Nothing else on the board seems fried, and the green power LED lights up. In case of a firmware glitch, is there any way of re programming it to fix the problem?
I bought it from Local Makers in Amsterdam.

Weird, I have the same garbled screen when I turn on the printer, but it goes away and the printer works perfectly. I assumed it was just a harmless boot-display-firmware-glitch. I think it is the same for you but after the firmware goes to the next step in the boot-up process, it hits a problem and halts.
If it is not something else externally (bad wall socket, power supply, damaged power supply cable), then maybe the board died. Where did you buy the printer?
