I Dredd the Issue

Letter received on Sunday May 1st 2016.

Sunday May 1st 2016

Just bought a JD but after a week of playing it, it now starts up by coils firing and message saying check fuse F114 and F115. I tried googling it and seems like a big issue, just not very electronically savvy. Should I take it in to a professional or might it be something manageable to fix? Thanks so much for all you do.

Dear Judge


With power off you could pull and check your F114 and F115 fuses.


You might need help though. At least hands on help. You likely lost 12 volts on the power driver board or U20 on the CPU.
