This one was completely dead — no power, no output, nothing. Traced the fault to the power supply circuit, specifically U14, a TC7662BC — a charge-pump voltage inverter responsible for generating the negative supply rail. Without it, the whole unit dies. You can also see U13, an LM78L positive voltage regulator, in the shot — both in the power supply section, both small SOIC surface-mount packages.
Removal was done with hot air under magnification, pads cleaned back with wick, and a fresh TC7662BC reflowed into place. The usual care needed to keep heat away from the electrolytics nearby — C12 and C15 are sitting very close — and to make sure the pads came through clean.
After reassembly, full power restored across both rails and everything working as it should. Couldn’t resist running it through its paces before boxing it back up.
