Hi,
while having another problem fixed the tech told us about fixing the shadow in the corner problem. check the tubes. he said when they get hot the glue around the tube melts and causes the problem. he removed the access glue and ours is all better, i hope this works for you too.
:-)

Vivtek d510 projector has black and white spots covering 1/3 of projected image


The DLP Chip is failing .The DLP or Digital Light Projection Chip contains up to 8 million tiny microscopic mirrors that tilt to project a digital image onto the screen. These mirrors are failing causing light and dark spots to appear.Unfortunately fixing this projector is probably going to cost more than buying a new one. Hope this helps.

The upper left corner of the screen (triangular shape, approx. 8" vert. and hor. from the corner) is showing dimness, not completely dark but maybe halfway. What might be causing this? Thanks.


This is your mirror tunnel. Light passes through the mirror tunnel to the DLP. The tunnel is made up of 4 mirrors glued together. Over time the glue comes apart and the tunnel shifts.

It starts out like this: |_|
and when the glue breaks down it does this: \_\

So the light, instead of passing through the mirror tube, goes through the ends of the mirror, so you get SOME light but not all.

I contacted RCA and they said:
"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. "
Awesome support! NOT! (That is the actual full text of the message from RCA support.)

I have some high temp epoxy and will be attempting to re-glue the parts myself.

Dark spots on screen on DLP when screen is white


What size are the spots?
If they are 1 pixel in size you have stuck DLP mirrors.
If they are larger not symmetrical then it's most likely dust blobs in the optics near the focal point (on the DLP chip glass window)

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?)

No, don't wait. Make sure you get RCA to cover this under warranty. Don't wait for everyone with this model to have the same problem and jam up RCA with the customer service nightmare that is rampant in this industry.

InFocus X2 Projector Fault


This error is to do with the light tube - 4 retangular mirror's just after the colour wheel. The dark band is where the bonding for the mirror's is failing, the spring clip holding the assembely inplace pushes the top mirror down slightly causing the dark band as mentioned.

To fix this use a high temp glass glue and very careful clean, reposition the mirror's (in the correct position). Allow to cure fully then re-assemble the unit.

I have only have had to do this twice the 1st time using a sub standard adhesive and dark return a few weeks later. The 2nd I did some reseach and have a quailty glass glue. The X2 has been fine for many years now with no sign of the band re showing.

hope that has helped you.?

ps. if you are rubbish at doing stuff like this - just don't try, it's fiddly and requires a good understand of what you are trying to achieve. A perfect retangular tube with parrallel sides...!!!
