Samsung LED TV UN60EH6000 HDMI ports fail to recognize any signal and by this I mean the TV gives me an error message on screen that says no signal detected-check connections.

An aux cable is designed for transmitting analog audio signals and cannot carry video signals. The Sansui SV21E11G TV also does not have any built-in features for screen mirroring or connecting to mobile devices wirelessly, so you will need to use an external device to connect your Samsung A32 to the TV.
Using an HDMI cable is a simple and straightforward method to project your Samsung A32 to your TV. HDMI is a digital signal that can carry both video and audio signals, and most modern devices come with an HDMI port. To use this method, you will need an HDMI cable and an HDMI adapter or connector for your Samsung A32, if it doesn't already have an HDMI port.
Wireless screen mirroring devices, such as Chromecast or Miracast, allow you to wirelessly project your smartphone's screen onto your TV. These devices use Wi-Fi Direct technology to create a direct connection between your Samsung A32 and the TV, and they can mirror the contents of your phone's screen in real-time. To use this method, you will need a compatible screen mirroring device, a Wi-Fi network, and a compatible TV with an HDMI port.

Switch off the TV, switch off power and remove plug and wait for 48 hours and retry.

on you r remote there should be three hdmi settings just try each one it will likely work with one of them

you could have a loose south bridge chip, you will need to do a re-flow.
also check any small resisters next to the HDMI port.

Ports on the monitor are for receiving the signals from the sources, not for sending signals out to another devices.
Your TV HDMI should be connected directly to the video source output, not through the monitor.
