TV Power Cords


Has anyone tried replacing the cheap TV power cord with an audiophile power cord?  What results did you get?  Picture Quality?  Sound Quality?  Did it improve the picture and sound or stay the same.   I have so many extra power cords laying around I just tried one in my 75" OLED Sony.  I will wait to report back my results.  I also have no idea where any fuses are on the TV and I am not about to take them apart to find out.  I wish they were visibly apparent or easy to get at.

If you can replace it, then you’ll easily see the difference.
Your eyes won’t lie to you like some say your ears will.
@terrycwk -  is this a DIY cable?  I see the strands but no connectors?  Can you elaborate please as to how this works?  How would it be different than the upgraded power cord that I am using now?
I changed the cable on our TV and did not really notice any change.

But when my wife turned on the TV, she asked "what had I done to the TV" - she noticed it was brighter, with better colour, contrast and details in the dark areas.

I've since learned what to look for and now my TV's have custom power cables.

Turns out I'm more like a bat - lousy eyesight, but GREAT HEARING.!

Yes they DO make a difference !
