Hi there, nu7020 , the led blinks all the time without stop, the power supply outputs voltages are not stable, jumps from 0v to the normal output, for example if one of the output should be 12v it jumps from 0v to 12v all the time, i thought its power supply problem but its not , if i remove the fuse which is before b13v_pw the voltages becomes normal, so its after this fuse, removed the fuse and injected 12v to check ifcany component heat up but nothing heats up, the amp is almost nothing, but the voltage on tge external power supply keeps drooping, even i dont know now if b13v_pw is shorted or not!! Q18 the other side of tgeckegs are shorted to ground, pls any one has tge schematics for this board? Or at least similar one to figure out how this board works? Thanks
