Common Causes Of Samsung TV Flashing On And Off

Samsung TV flashing issues can stem from various factors. Below are detailed explanations of the most common causes.

Power Supply Problems

Power supply problems often cause flashing issues in Samsung TVs. A faulty electrical wall outlet might not provide consistent power. Damage to the TV’s power supply from a power surge can also lead to this issue. Checking the outlet with another device helps rule out an electrical problem. Inspecting the TV’s power cord for signs of damage, such as fraying or wear, provides additional insights. Using a surge protector can prevent future incidents due to power surges.

Faulty HDMI Connections
