HDMI port not working

hdmi wont work and wont display on tv. It wont let you uninstall games nor install them

If your hdmi is not working installing or uninstallig games is the smallest problem. U should open your console and locate “retimer”, it’s small chip that controlls hdmi output. I hope u have some multimetr. Then you need to check capactiors around this chip(On multimetr u should choose this mode with buzzer or diode test). In case of capacitors there shouldn’t be any short circuit. U can check too hdmi pins if they are ok.
On “fixit” u can find teardown of xbo S
