Okay, here goes. My 2002 ULT (Bro)sew/emb machine has been acting strangely. Turn on, yellow lite (instead of red-green when foot is down), the screen is black. Finally the screen lites up and resets the needle. This continues several times before I can begin to sew..which is only a few stitches before the pattern starts all over again. I took it to my local repairman--he cleaned all contacts, but unable to diagnose (mostly works on DSM's. So off to auth. dealer. She diagnosed as needing power supply unit, which is no longer available. However, I discovered I can tap on top, side, end..all displays come on..tho it soon goes off again. I layed it on it's back and was able to sew at least 2 yards of stitching. Does this sound like the power supply or a loose connection? I don't think the machine was ever REALLY looked into--it was in shop for 4 months because they were relocating. I finally called abt it and was told it was ''out back in storage bldg, would look and see what the status was, and return my call. Five days later I got the message that she had a Babylock once that acted this way and it was the power supply. I don't know which way to go now--I searched for the PS, but not to be found. However, I'm not convinced it is needed anyway. I loved sewing on the machine--I have 5 others for emb. Any suggestions-anyone ever experienced these symptoms? TIA for help or advice.
