Best DIY tweak?

Sorry Ozzy no way to post pictures....This is a very easy tweak, your just wraping the (center >copper< pin of the cable) with teflon tape and then pushing the the tape up to the base of the center copper pin. This makes non HDTV look a lot better....sharper..cleaner...brighter........darker colors!

Okay then......
For the tech-savvy, why might this be??

Is this, like the brass screw tweak, a "dramatic" improvement?

If you want

sharper..cleaner...brighter........darker colors!

don't most TVs have adjustments for these qualities? Although I rarely watch TV anymore, if I recall mine does.

DIY solid core powercables, 12-13awg. Mine is shielded too. Cleanest and most powerful current you can get. If you nedd any extension-cable make it solid too. Big powergain!

Replace the in-box powercable from rear wall to off/on-switch and back to trafo with solid too and your boxes will climb several classes in performance.

I simply tell the wife to go shopping for a few hours.
