little

Thanks, I think that I'll need a new one as you say but I don't like to make garbage with theses things, we are going to finish with the planet changing devices because of problems with small devices. Best regards!

I can't see anything else...

The brand is Liyu, you are right, the only part number that I can see is the one writen in the sticker, 1219 and the text in the botton of the image attached in this other picture

Thank you for you reply, I've been looking for main boards but I can't find one just like this. I think that this is too old. I've been looking in Ebay, Aliexpress... but I didn't dind. Do you know other sites? Best regards.

Hello everyone, I have a SC631 since 10 years ago, I use it as a hobby, not for professional use, and I've done a lot or stickers with it, but... Last week the plotter started showing extrange characters in the LCD screen and stopped working, I don't know wich can be the problem, can anybody help me with this? Everything looks ok, I checked the wires and the mainboard (until my knowledge reaches I can't see no one component broken). I don't want it in the garbage for a little problem. Help please. Best regards.
