Thanks for joining me. Today we're going to talk about CRT rear projection TVs and how to keep them young and vibrant looking. Why? We've got new TVs we could buy out there.
First of all, you spent thousands of dollars on your set. Why buy new? That's another couple thousand out the door.
Second, they last and last and last. I know of one owner who has a 20 year old set and he won't part with it. It looks fabulous. They also can give you the best HD out there. A finely tuned and finely dial CRT rear projection TV is the rival of anything else out there.
How do we we keep our projection TVs young and vibrant looking? The one thing people don't know is that there is a 28 surface optical pattern there that gets dirty. It's that simple. These optics have to be cleaned every year, and the deeper optics every couple of years. Why? 30 thousand volts, that's what it takes to use our CRTs. That causes everything to be statically charged, the air included, everything in the air no matter how big or how small, if its airborne, gets drawn onto those lenses, those lenses and there on the optical surfaces. Then you have a bright object against a black background, it's not a crystal clear background. It's got all this haze to it. In an afternoon it can all be cleaned up.
You have to be very careful about what you use, you don't want to use ammonia, you don't want to use anything that's going to scratch the surface, and you have to have something with a high absorbency content too, and not just move things around and leave residue.
Take a look here ... from the look of these lenses, full frontal, hmm, not much seems amiss. But let's change a few things. Look at them at an angle and let's add some light. Now one of these lenses is clean, the other two are dirty. What do you think?
You only get one shot at cleaning your optics each time, don't blow it, do it right.
Bob Jones, thanks for listening.
