I am working to repair a M5126 backlight Mac Portable. Recapped, repaired a few traces and I have the machine doing a good happy chime but when I connect an external (with power and correct INI file) or an internal bluescsi (portable version) it will still give me a good happy chime and then then the SCSI light will blink once and I get a Sad Mac 0000000F/00000002 error code. I have traced out the RAM logic schematic made by Danny Cellar and found no issues. I have gone over the SCSI, IWM to try find broken traces and other new found. I have tried different SCSI chips where some will not give me the sad Mac error but I get the no boot image found icon instead.
If anyone could have any suggestions to try to solve this problem would be very much appreciated.
Thank you in advance
