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.  
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 !

@willgolf - yes, this is a diy cable and I paired it with the Furutech’s FI-50 ncf connectors.  Sorry that I have never tried DH Labs cables so really can’t compare the two.  But for many years Nanotec power cords are quite famous for their use in video applications especially in Asia so you can do more research and maybe give it a try.

I got mine from these guys as I live in Vancouver Canada.
@bajaed - I use my own DIY cords.

If oyu are not into DIY take a look at KLE Innovations power cables

Hope that helps - Steve
What connector to the TV do you use?  I had to jam my PC in as it was too big.  Need a smaller female head.
