Strange Rear Projection problem
 

I just got a Samsung pcn5425r rear projection tv. The upper assembly was
removed from the bottom. It also came with two screens, a fresnel looking
screen, and a clear one. They were taped together. I got the tv together
and got the convergence really really close. I have sharp text and sharp
picture. However, the three colors, RGB, are separate from each other, so I
get a screen that is basically split into thirds, one for each color. I can
also see the reflection of the guns through the screen. Any help would be
appreciated. I am not a repair tech, just a wannabe.

Sounds like the electronics are probably fine, now you must have something
wrong with the way the screen itself is put together, either that or you're
missing a piece.

The top of the set was just the shell, with mirror still attached, and
the two pieces of screen, which I sandwiched together. Would there be
anything else in there?

you said there were two pieces, a fresnel and a clear one? there should be one
with small parallel vertical stripes on one side; it goes between the fresnel
and the clear one. Also, the fresnel may be backwards; some mount the grooved
surface twoards the CRT's, and some facing the lenticular (striped) lens.

Also, if the "Lenticular" is installed upside down it will affect the
quality of the picture. I'd bet that you only have either the "Fresnal" and
"Protector" screens or only the "Lenticular" and "Protector". As posted
there should be all three. Fressnal inside towards the Mirror, Lenticular
with the ribs toward the viewer, and the Protector on the outside. If there
are any small white paper tags on the screens they should be at the lower
left corner.

Thanks for the reply to everybody. I believe I may in fact be missing a
screen, the lenticular as you said. Do you know where I could get such a
screen??

From the manufacture...

You might get lucky and find a suitable used one but it sounds like the rest
of the set is in good shape so it's probably worthwhile to buy a new screen
if you have to.
