An unstable power supply

If your Samsung smart TV keeps losing its HDMI connection while connected to an AVR or gaming rig, then this might be due to unstable power coming from the wall outlet into your HDMI switcher.

To check if it’s the case, try plugging in your tv directly into the wall power outlet and see if the HDMI connection is stable.

If you find that there is no issue with connecting to the power source unplugged from any switch or AVR, then this might be a sign of an unstable power supply coming from your wall socket. You can try to plug your device into a power strip or UPS.

Poor HDMI port on the tv

If you are using an AV receiver or switching devices with multiple HDMI ports, then it is common for one of the ports on this switcher to work while some don’t. If this happens to your Samsung smart TV , simply try connecting your media source to another HDMI port on the switcher.
