Re: Diagnosing non-functional Emax

2014-02-18 by David Sotnick

Well I opened up the Emax again, all PSU voltages were good at the floppy and inverter.

Taking a scientific approach, I went over all the mods I made, pin by pin and found some cold solder joints on the new OLED display I installed.

Fixed those and she's back!!!

*phew*
