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)

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 checked all the lines, I have unplugged from the wall for as long as 12 hours. Can anyone offer any help?… Please and thank you

  7. 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.
    I have tried to reset it, what else can cause this?

  8. I haven’t a Hisense 55″ TV which is almost 2 years nowt it started flickering 2 days ago. Are there any fixes for this?

    So far I’ve tried turning off and on for couple minutes.
    Also, pulled the cable and removed other appliances on the surge power point.
    The issue still remains…as soon as I turn on after a few minutes it just starts flickering and then goes black!

  9. I have a led vizio 700i b3 70″ I’ve been having problem with HDMI connections. I have changed the logic and power supply boards twice, changed the hdmi cable, the video/audio adapter last time I was trying to connect the cable on a different hdmi inputs I tried to turn on the tv but never turn back on, the next day I noticed a very soft blue color on the screen stays on for a few seconds and then you have a black screen, this is repetitive, soft resets won’t work. Can this be a t-con problem???.

    Years back I used to pug and unplug the hdmi cable while the computer and tv were on, and didn’t have any problem. (didn’t know better) The only board i haven’t replace is the t-con everything else is new. The root of the problem is HDMI.

  10. Hisense 50in 4years old flickering picture for maybe an hour then it dies..Turn it off leave it for about an hour turn it on flickering picture returns then dies again and the same happens..who wants it, I bought another..not I may add a Hisense

    ken roberts,
    What year and model number is your Sharp 46″ television?
    Also, where is the “pop” coming from? (Speakers, From the back of the TV?)
    It may just need an inexpensive control board or other component to fix your issue.

  14. Sharp 46 inch TV turns on and then goes pop.
    I turn it back on and it does the same thing.
    I think it’s gone for good.
