Xbox Series X overheating: fan clean, heatsink and thermal paste
A Series X that runs loud, shows overheating warnings or switches off in games usually has blocked vents, dust in the top fan and heatsink, or tired thermal paste and putty after years of use. Fix placement first, then open the back, clean the fan and heatsink, and if that's not enough, replace the APU paste and memory putty.

Xbox Series X|S no picture / no signal: HDMI port and retimer checks
A Series X or S that powers on but shows no picture is often a TV setting or cable problem, so rule those out and reset the video mode first. If the console is still blank on a known-good TV and lead, inspect the HDMI port for bent, shorted or lifted pins and replace it. If the port is good, the fault may be in the HDMI path on the board, including the retimer chip.

Xbox Series X|S won't turn on: power supply vs mainboard checks
A Series X or Series S that does nothing when you press the power button is usually down to the mains lead, the socket, a tripped internal supply or a failed internal power supply unit; a smaller share are mainboard faults. Work from the outside in: reset and swap the simple things first, then open the console, check or swap the internal PSU, and only then look at the board.
