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.

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

Click click repeatedly faded then red blinking light


Go to the video menu and turn the color control to minimum. Determine if you have a black & white picture or is it green & white. If the picture is greenish, you have a problem in the screen circuit or possibly a bad picture tube. If the black & white is ok then I would suspect a problem in the chroma circuit such as a bad video jungle IC or a crystal. However, because your set had a red blinking issue prior to your existing condition I would lean towards the picture tube as the source or your troubles. You can try a simple test to determine if you have an intermittant short . Take the back off the set, and with the insulated end of your screw driver, very very lightly tap on the neck of the picture tube near the socket. If you see green flashes or hear loud snaps in conjunction with your taps or the green tint goes away, chances are the tube is the cause. If so, you might try installing an isolation transformer on the picture tube. Good luck
