Hi there,

Have a Stern Lightning that refuses to boot.
When testing, the 5v is generated fine on the power board, but there is no 5v at the MPU.

I have seen in the schematics that this comes from connector J4 on the MPU; can someone lead me to where is the other side of this connector?

Thanks a lot

Quoted from zacaj:

Probably J3-14 on the driver board. There should be a page in your schematics that lists every connector pin and what it connects to though.

Haven't seen it, using the ones from ipdb

No continuity with J3-14
