Used RPTV Screen Replacments?
I have a 52" RCA (PTK195) RPTV that I bought used as non-working. Did some
solder touch-up on the power supply for the convergence board and it's been a damned fine set since. Everything was in perfect condition until two nights back when moving furniture... A coat rack that was not stable on carpeting took a tumble...and took out the screen! Well, it managed to just put a nice spiderweb of cracks in the lower left hand corner. Of all the crap I have that it could have broken, it had to fall right into the RPTV. Oh well... The set is still quite usable although I do want to find a new screen eventually. Can I purchase a screen from any old junk set and cut down down to fit the cabinet? There is a pawn shop nearbye that has a trashed 60" set sitting outside but the screen seems intact and I'd like to see if they are willing to sell it if it will work for me. I know the screen is actually made up of two layers - I believe one is lenticular and the other is fresnal? In any case, I've learned by experimenting that if I rotate the screen, the image is screwy. If I turn the screen upside down, it's again screwy, but it a different manner. So obviously the screen is meant to be mounted one way only. My concern is that this other screen will be ''different" in some way and not give me a proper image. Should I just shell out the $150 for a genuine RCA screen or are chances pretty good this used screen will work? Thanks, -Steve |

Used RPTV Screen Replacments?
I'd recommend just buying a new screen from RCA, $150 sounds pretty
reasonable actually. You may wanna try to get the fresnel from the one at the pawn shop though, those are pretty cool. "Steve Reinis" wrote in message ...
