Best DIY tweak?

Put a little Teflon Tape from Wal-Mart on all your AC plug's prongs! ( Take about 3 inches of teflon tape and wrape it around each ac plug prong and then push them all the way up the prongs

What does putting plumbers tape on the AC prongs do other than potentially hinder current flow??

What does putting teflon tape on the ac prongs do? It cleans up that very dirty ac power a little.....I also put teflon tape on all my inside wiring in all my gear...my TV too.

I put some teflon tape on the center pin on my cable from my dish to my satellite receiver....(You take about 2 inches of tape and put a small hole with a paper clip at one end and put that end through the center pin of the cable and then use the paper clip to work the teflon tape around the center pin tightly and then push the teflon tape all the way up to the base of the center pin of the cable and then hook the cable back in the dish and satellite receiver) THIS IS A MUST TRY TWEEK!!! WOW!

Hifisoundguy, I am interested in what you have written but not sure I understand exactly.

Are you basically saying to wrap the bottom portion of the center RG6 cable with Teflon tape and push the tape down tight where it touches the Connector barrel ?

Can you send me a picture ?

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!
