Question about RCA D52W20 52" Rear Projection HDTV-Ready Television
Did you ever figure out how to fix your shadow problem. I have the same issue.
It's the light tunnel. The tunnel is a square tube made up of 4 mirrors glued together.
It looks like this from the side: |_| (with a piece on top too.)
When the glue breaks down, it shifts inside the little mirror holder. The shifted mirrors looks like this /_/ what you are seeing is the shadow of the tilted mirror tunnel.
ON the RCA's there's not a good fix.
"Ok, well sadly they do not offer the light tunnel anymore, which is what you need. Sadly you would be rendered to get a whole new light engine assembly. That would be the D.N.D module, light tunnel,color wheel,optic spanner, and oci. mirror. Your best bet would be to search ebay for a broken engine and replace it that ways."
That is the ONLY response I got from them.
I took the set apart and found the 4 tiny mirrors. I will be attempting to epoxy them together. (The set is dead anyway, why not try?)
