enable - 7 pin of GS7256, chek connected to NPN trasis around... (may be Q1604?)
this, seriously enable pin 7, but in the multimeter there was no voltage there, thanks for the answer, for example, to see the image on a pcb there was no gpu installed on a 110 ohm coil resistance, to resell a gpu the resistance dropped to 19, and the Gs returned to work, apparently he was in protection, problem solved I will close the topic.
