Hey there everyone,
Officially stuck with this one and I think it may be a bad FV chip but since this board came with the chip pre-soldered, I wanted to see if anyone had any other insight as to what might be going on or things that I could check. As it stands now, I am getting good audio into pins 1&2 on the FV however I am getting nothing out at pin 28; no hum, no low volume, only hearing the ringing in my ears which is a totally different issue!
I checked each pin on the FV and continuity looked good from all of the points. The pots are properly affecting the voltages on their respective pins, and all of the grounds looked good as well. I’ve attached a list of voltage readings/results that I received, and some pics of the board. Sorry for the underside ones! Tricky to get a shot with the pots in place. Under the magnifier all of the pins looked clean (no bridges) on the FV but I tried reflowing solder on the points anyway with no changes. Also I should note that I get clean signal but if I turn the Mix to wet, I get nothing.
Please let me know if I can provide anymore information and any help would be greatly appreciated! THANKS!!!
