Xbox one HDMI Cable not working

My Xbox one HDMI cable won't connect to my T.V. meaning that I don't get a signal. I had this problem before and I switched the leads of the HDMI cable around and it started working again. Now I have tried that and it still doesn't work. I tried multiple
T.V's and tried a different HDMI cable and I still recieve no signal. I already had to have my Xbox one replaced because it would shut off on its own, so they sent me a new one and it worked perfectly fine until now. Any suggestions?

Xbox One X bundled HDMI Cable is faulty

Hi,

the HDMI bundled with my new Xbox One X is not working since the day of purchase. The TV does not detect the Xbox if connected with this bundled HDMI cable. I have tried to connect my friend's Xbox One X with his TV (different from my TV) using my bundled
HDMI cable but the result was the same i.e. his TV did not detect his Xbox. I am using a 3rd party HDMI cable in the interim to connect my Xbox One X to my TV since the day I bought this console. I am pretty sure the bundled HDMI cable is faulty. The retailer
who sold the console to me (Harvey Norman Singapore) refused to exchange the faulty cable for a new working cable and instead asked me to contact Microsoft support. They also mentioned that my Xbox is covered under Microsoft on-site warranty and that once
I contact Microsoft support, I will receive a new working HDMI cable for my Xbox One X from Microsoft.

Please advise on this.

Thank you
