I have a toshiba tp50h50 rear projection tv and their is a blue shadow behind the words and makes the words a little blurry

Sounds like you need to do a color convergence. If you still have the owner's manual, it will give great detail on how to do this. The convergence menu is accessed from the video menu on the tv.
The tv has three color picture tubes, red, blue and green. The convergence alignment adjust each tube so that color from each tube overlaps each over to create a white image on the screen. Most tv's only allow you to adjust the blue and red colors.
Convergence should be performed each time the tv is moved and at least once annually.

I have a Sony Trinitro 36" about 8 yeras old. When I first turn it on, I can hear the sound but the picture goes in and out a few times before it stays on, now it is doing it every once in a while during...

Its a good bet that the picture tube is going bad. Thats the classic symptom of a failing tube. The tubes if available cost more than new tv's.. Sorry

Black screen but have sound

If it is not a hardware problem, it is most likely the Closed Captioning system.
If you can still see the on-screen menu, go into your TV's menus and disable Closed Captioning.
