Napalmtree Posted May 22 Report Share Posted May 22 (edited) My power supply failed and took the sammichFM out with it. I replaced the rectifier and VREG and am getting proper voltages across the board except some of the digital 5V spots. Mem banks 2 on right all have digi 5v, but the PIC, midi chip, 3 left mem banks, and upper board socket are onpy getting 1.76V. Nothing looks burned and diodes check out. Wondering what could be shorting that line and not affecting the mem banks. Thinking it's either IC caps or a transistor. Any ideas welcome. Gotta bring this back to life. The failed supply spiked voltage up to 15V+ Edited May 23 by Napalmtree Quote Link to comment Share on other sites More sharing options...
