You’re not alone if the only thing that displays when you switch on your Samsung TV red light blinking! This is a widespread issue among Samsung TV users.
If your Samsung TV doesn’t power on but the red light blinking, it could be due to a faulty power supply. If it’s not covered under warranty, you’ll have to replace it, which can cost anywhere from 200 to 350 dollers. It’s also probable that the HDMI port isn’t functioning properly.
