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.
