Short identified on the board's fets, possibly caused by dry thermal paste. | Replaced two 30f124 and two 30j124 that were shorted and applied new thermal paste to all components of this board. I also advise you to resolder the power supply board and zsus, as they were already quite bad. | Flavio |
