A blinking or flickering television can occur randomly. This dimming TV screen effect can seem like a strobe light and show flashes of black. A flickering TV that blinks can sometimes be fixed by simply turning the TV off and back on.
A component attached to the TV could be at fault. Cables may not be secure or a cable may be faulty. Check to see if your TV has an energy efficiency feature that can be causing the issue.
Disable some of its energy efficiency features such as the Eco Sensor or the Energy Saving feature to keep the brightness level consistent. (Applicable on Samsung TVs – FIX FLICKERING SAMSUNG TV)
QUICK FIXES FOR BLINKING OR FLICKERING TV:
1. Turn the TV OFF and then back ON to RESET the TV.
2. Unplug the TV from the POWER OUTLET for 5 minutes to reset.
3. Check the CONNECTION OF CABLES going to and from the TV.
4. Disable ENERGY EFFICIENT features in TV MENU.
5. Check if there is a FAULTY COMPONENT connected to the TV.
6. Change the INPUT SOURCE to see if issue is with the TV or a component.

LOOSE CABLES CAN CAUSE ISSUES
TV FAULT, CABLE ISSUE, or COMPONENT MALFUNCTION?
If the TV does not have any cable issues and all components check out to be working, the TV itself may be malfunctioning. Most TVs have a backlight that can malfunction and have an issue with the liquid crystals. When this occurs it can cause the picture on the screen to blink, flicker, or dim.

I have a 55 inch RCA Flat screen TV.
2 years old or a little less.
You turn it on and it starts flickering right away, some times real fast then it slows down then speeds up.
The TV has a beautiful picture.
