Re: Acer aspire 5943g repair
Ok, I was doing some other stuff when I found some spare rt8206b chips. So, I replaced PU6, and I guess now B+ is about 12.5v (fluctuating between 12.2v & 12.8v), and I hear a fast ticking sound, probably from when voltage builds up in a coil. +3valw and +5valw are not working (ohms to ground PL5 5ohm, PL4 1.3 ohm) and very low voltage.
I recall lifting those coils and found the shorts to be on the rail (probably wrote about it in an earlier post). But, since the ticking sound there are still Mosfets to be checked on B+
