The Xbox Series S 512GB outputs video from a single HDMI port on its back, and a screen that stays black means the signal is not arriving or the console has chosen a mode the TV cannot show. Begin with the simple checks: confirm the TV is on the right input, that the HDMI cable is firmly in the console's HDMI OUT port and in the TV, not a TV's HDMI IN designated for another device, and that the console's power light is white.
The checks in more detail
The Series S supports 4K upscaling and 120 Hz on a suitable TV, and a TV that does not support the mode the console selected can show nothing, so use a different HDMI port on the TV, ideally one that is marked for 4K, and a different cable, preferably the one that came in the box, because a poor or old cable is a common cause. Turn the console off completely by holding the power button on the console for about ten seconds until it shuts down, wait a minute and turn it on again, as Microsoft's console hardware help describes. If the console starts with its start-up sound but the screen stays dark, the display settings may be at fault.
Connect the console to a different TV or a monitor to check; if the picture appears there, change the video mode in Settings, General, TV and display options, Video modes, and set the resolution to a lower value, switch off 120 Hz and Variable refresh rate, and disable HDR for a test. Some TVs need Game Mode and a firmware update to cope with the console. A soundbar or receiver in the path may block the picture, so connect directly. If the console shows a green screen on start-up, it is updating or in recovery.
If no TV, cable or port gives a picture and the console powers up, its HDMI port may be damaged, and Xbox support can arrange a repair. Always handle the HDMI plug gently. If you recently changed TV, a monitor, a capture card or an HDMI switch, remove that change first, since each can negotiate a different mode with the console. A capture card that does not pass 4K or HDR is a frequent cause of a black screen in an otherwise working set-up, so connect the console straight to the TV for the test and add devices back one at a time.
