Help FP and Fdle Leds always ON on a Stim

Post by ersus »

Hello, just finished assembling my MS2 V3.0 PCB, I check the volts in the U1 and everything is fine but in the Stim the Fdle and FP led is always on, even without the processor. I check the position of diodes and all are well, I searched a short circuit but everything seems fine, which may be the problem.

Since it appears to be happening without the processor in place, it must be a fault on the drivers - most likely a solder bridge at one or more of the transistors.
