Re: triangular shadow on the upper left corner

You may have a dirty or blocked mirror. You can usually take the back off and clean them. If you don't feel confident about it, a repairman can do it for you. If you clean it yourself, I recommend using a good quality glass cleaner and any type of towel that doesn't produce lint. Coffee filters work very well. Don't leave any streaks!

There is a shadow in the upper left corner of the screen

someone is going to have to look inside by either removing the rear upper part of the set or removing the entire front screen---neither is easy to do. But considering your trouble I would not be surprised if the mirror is cracked---the entire front screens would have to be removed to replace the mirror--special mirror and special handling--I have seen several break when someone is not careful putting in.

I have a 5 year old RCA 61LPW42 HD DLP television. A few months ago a small dark shadow appeared in the upper left corner of the screen. Over time it has creeped down and become larger. Still starting...

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.

RCA's response:
"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?)
