Why would you have 5 bars of reception on the tv then there is no picture and a message says no signal.....a second ago there was a beautiful photo....What causes that??

the aspect ratio for modern programming is 4:3 older pgming like your ST and TZ have an aspect ratio of 16:9. your hdtv's remote should have a button labeled "picture size" or something similar. when an old rerun comes along use that button to change the aspect ratio to 16:9 and the old programming will look better.
That's true, except the actual ratios are backwards. The old TV (and before that, for many years, movie) aspect ratio was 4:3, the newer (wider) HDTV format is 16:9. Widescreen movie systems vary some in what their aspect ratios are.
I am somewhat amazed by how many times I see the wrong aspect ratio on TVs in restaurants and so forth. It's particularly strange to see a 16:9, presumably digital, broadcast being shown on a 16:9 digital TV with letterboxing (i.e. black bars at the top and bottom) and squishy people. Does nobody else actually notice that the basketball players are all short and the ball not round? Do they really mean to avoid using some of the screen that they paid good money to buy? It boggles my mind.
