I thought the display board was bad so I changed it out. It worked for a couple days and now it doesn't again. I then took both boards to the same type of machine and on there they both work. What do you guys suppose is wrong? I'm thinking main board but, that is costly! please help.
another machine and they both worked for more than a couple of days? If so then your first machine probably has a logic board problem. I can provide an exchange logic board for you if needed. You can contact by via the email link in this post.
