Okie-doo, boys and girls. Here's the dill.

Picked up an OLD tv off of Craigslist (not a Mitsubishi RPTV, but everyone's gotta start somewhere) and it's a Phillips 55" 55P8341.

The screen has what looks like tw fresnel lenses behind it that the picture is projected onto. These are "caved in", away from the screen on the right hand side, right now. Beginning to tear TV down to nuts and bolts to see how many extra pieces I'll have left over when I put it back together, and have a question or two.

First, there is a liner that the fresnels slide into to hold them in place. Looks kind of like a clip on all four sides that extends out from a piece of wood set to anchor clip in place. I can get MOST of the fresnel to fit behind 3 of the 4 clips. At this point, the lens doesn't want to bend enough to fit behind the 4th clip (One for each side). I'm becoming worried that I will have to remove the actual piece of wood, position the fresnel, and re-staple the wood in order to do this properly.

Also...in all my brilliance, I didn't realize the mirror was Mylar at first. Where do I find replacements, now that I sprayed Windex on it? I know, I know, newbish in nature, but it happens.

I've found an awful lot of spare parts out there. Are there boards I can install that will allow for HDMI, more component inputs, stuff like that?

I wish you luck. But I think you will find that refurbishing this low level tv may start to cost you more than buying a working used tv. You may be able to find parts, but they can get expensive. And when you are all done, you will still have a Phillips tv, which is like pouring a bunch of money into refurbishing a 1975 Oldsmobile, why???

I'm gonna take a little time to take it apart and put it back together. It's also gonna be better than any of the TV's currently in my house.

So, can we get back to the questions I was asking? How do I get the fresnels back into the clips without removing the clip from frame of TV? This is the main, most important things I'm sweating, right now.

*Edit*

Guys, can we please focus on the questions I'm asking, instead of whether or not a particular TV, or manner of thinking, measures up to your own standards? I'm becoming very frustrated with the attitude I'm encountering from a large number of you. This is supposed to be where the SMART people are...but the impression I'm getting is that of a bunch of people looking down their noses.

Okay, got the problem with the lenses worked out. Popped off the front, and there were four bars that unscrew. What I'm trying to figure out now is the lenses. There's a fresnel, the tv screen itself, and a third lens that goes between the other two. Looks like maybe it focuses light and shoots it out at a particular angle from the tv. This makes off-axis viewing...interesting. Can anyone clue me in as to why the third lens is necessary?
