Samsung TV Turning On and Off Repeatedly? The “Boot Loop” Explained The Frustrating “Click of Death” You sit down to watch a movie, press the power button, the Samsung logo appears, you hear a “click,” and the TV shuts down—only to turn itself back on and do it all over again. This endless cycle is known in the repair industry as a “boot loop.” Why Does This Happen? Failing Capacitors: Over time, the capacitors on the power supply board can bulge and leak. They fail to hold enough charge to boot the screen fully. Corrupted Mainboard Firmware: A recent background update may have failed, corrupting the TV’s operating system. Short-Circuited Screen Panel: If the actual display panel has a microscopic short, the TV detects the power surge and immediately shuts off to prevent a fire. How to Break the Loop First, try unplugging the TV from the wall for 10 minutes to drain residual power. If it still loops, hardware replacement is necessary. For fast, reliable Samsung TV repair in hyderabad, our technicians carry genuine power boards and diagnostic tools to stop the boot loop permanently.
