Just picked up a shadow that was playing fine at friends home. Got it home and factory settings message came on- assumed batteries were dead, so tried to enter test menu- buttons do not work. Replaced batteries and now get Check Fuse 114 115 error. Fuses removed and toned fine. Service menu buttons do not work. No acid damage seen on battery holder or MPU.
Started to follow test for error message. First says check LED6- this is not on. LED1 is also not on. Here is where I need help. I assume the service buttons do not work because its not getting voltage. I tested the service menu button wires for continuity to molex holder and they are fine.
My board service level is nil but I am willing to trouble shoot more. Guides say to check BR1 on power board and D1, D2 diodes on CPU board. Is this correct and what do I check and what settings on DMM?
Thanks for help
