TV screen flickers or flashes during use
Most flickering is caused by loose HDMI cables, energy saving mode, or an unsupported refresh rate. Checking the cable, disabling power saving, and switching HDMI ports usually fixes it.
When your TV screen flickers, it's either losing signal (loose cable), the energy saving mode is causing problems, or the refresh rate isn't compatible with the input signal. We'll check the HDMI cable, disable power saving mode, verify refresh rate settings, and try a different HDMI port.
- ✓Keep your TV remote nearby for accessing settings
- ✓Note which HDMI input the flickering is coming from — test on different inputs if possible
- ✓Have access to the back of your TV to check HDMI cables

Skip, I just want a technicianCommon mistakes to avoid
- Thinking the TV is broken when the problem is a loose HDMI cable
- Not checking the HDMI port itself for bent pins or damage
- Leaving energy saving mode on — it genuinely causes flicker that looks like hardware failure
- Not trying a different HDMI port to isolate which port is failing
Signs you need professional help
- If the flickering continues after checking the HDMI cable, trying different ports, disabling power saving mode, and restarting the TV, there may be a hardware issue with the display or HDMI input module. Get in touch and we can help determine if the TV needs repair.
