I have a bernina 640. A while ago, I noticed that there was a line through the LCD screen. The machine still worked fine. I have another machine so I am not using this one all the time. I went to use it the other day and it wouldn't turn on. I took it to my dealer to get it fixed. It needs a new power supply. The power supply is $155 and the LCD is $360. Labor is another $190. If I just do the power supply, labor will be around $150. If I wait and do the LCD later, the labor will probably be another $150 . So my question is: Has anyone had an LCD screen go out on them? If you did, how long from the beginning until you really had to replace it? Money is kinda tight right now but if it looks like the LCD won't last long, I'd rather combine the labor costs. Thanks for your input.
