You're not alone — and in most cases, this is completely fixable without a technician. About 80% of Samsung TV flickering issues are caused by software glitches, settings problems, or loose connections.
This guide covers the 3 most effective fixes that work on QLED, Crystal UHD, The Frame, and all Samsung Smart TVs (2018-2025 models).
FIX 1:
Fix #1: The 30-Second Power Cycle (Works 60% of the Time)
This is the most effective fix — but most people do it wrong.
Steps:
Unplug your TV from the wall outlet (not a power strip)
Find the power button ON the TV itself (not the remote)
Press and hold that button for 30 seconds
Wait 2 minutes with TV unplugged
Plug back in and turn on
Why it works: Holding the power button drains residual charge from the capacitors, performing a true hard reset of the internal electronics.
FIX 2:
Fix #2: Check Your HDMI Connections
Loose or damaged HDMI cables cause more flickering problems than most people realize.
Steps:
Unplug all HDMI cables from both ends (TV and device)
Inspect connectors for bent pins or damage
Plug back in firmly until you feel it click
Try a different HDMI port on your TV
Test with a different cable if available
Pro Tip: Samsung has a built-in cable test. Go to Settings, Support, Device Care, Self Diagnosis, Signal Information, HDMI Cable Test.
FIX 3:
Fix #3: Disable Eco Solution Settings
Samsung's energy-saving features auto-adjust brightness based on room lighting — this often causes visible flickering.
On newer TVs (2021+): Settings, General & Privacy, Power and Energy Saving
Turn OFF: Brightness Optimization Motion Lighting Brightness Reduction
On older TVs: Settings, General, Eco Solution — Disable all options
