RTX 3080 · No display
Fans spin, PCIe 12 V present, no signal on any output. Core rail dead at 0.02 V.
Traced to a shorted MOSFET on phase 4. Two replacements, one reballed memory module, and it posts again.
Two engineers, one hot-air station, and a queue of things everyone else already wrote off. Graphics cards, consoles, laptops, and the appliance boards that fail three weeks out of warranty.
Every episode is one board, start to finish. Nothing edited out — including the times we lose.

Console boots to fan and light, blank screen. Retimer IC reads open on two data pairs.
Bent pin on the port plus a cooked retimer. Port swap, chip swap, hot air, done in one sitting.
Programme starts, drops out after four minutes, no error code on the display.
Three bulging electrolytics near the heater relay and one cracked solder joint. Ten euros of parts against a €280 board.
No power. Corrosion across the SMC section, several pads lifted under the connector.
Cleaned, rebuilt two traces with jumper wire. It ran for six hours, then the CPU rail collapsed for good.
Drum stutters on spin, burnt smell, brown residue around the triac heatsink.
Triac and gate resistor gone, snubber cap out of spec. Replaced all three and added a proper thermal pad.
Dead on any cable. USB-C port looks fine under the microscope, PMIC gets warm.
Fake third-party charger took out the M92 chip. Replaced it, reflowed the port, tested on four cables.
Same four stages, every time. If we skip one, we usually pay for it later in the video.
What it did before it died, and what the owner already tried.
Schematic, multimeter, scope, thermal camera. Measure before touching anything.
Hot air, microscope, and the actual technique — filmed close enough to copy.
Works, or it doesn't. Cost of parts against the cost of a replacement.
The groundwork. Watch these first and the teardowns stop looking like magic.
