Hello everyone,
This will be my first post on this board, wanted to make sure I do all the research first and read previous posts as there are a ton of threads regarding the 7 red lights of death before I post anything on here, I am just totally at lost at this point and feel like I've tried everything.
Bought used parts from Ebay that claimed are working and replaced the SU,SD,SC and still got the 7 lights. I isolated the SC board from SU and SD as instructed in the repair manual and received the 7 lights. Checked resistance at SC2 across both pins (no short), checked resistance at Vsus (no short). Are there other points that I can check on the SC board?
I also checked both the SU and SD for shorts, everything seems fine (unless I am missing something) VFO checks out, VF5V is good, checked all the pins for the ribbon connectors to ground, no continuity. Everything points at the SC board. I contacted the seller on ebay and he sent me another board also used, same problem. I asked him how he's testing them he has no idea. I may just be getting faulty boards over and over again.. any help would be greatly appreciated. Thank you
