    Considering you posted this back in 09/07, I'm not sure if this will be of any help to you now; other than to limit the number of holes you might put in your walls :). Nonetheless, I thought you might want to know of an issue I've recently come across. In particular, some vendors; particularly Xbox 360; is updating their System Software for Auto Detection. Wherein as, their forcing the Native Mode of the connected device when their devices are connected through HDMI to DVI or any other conversion. After beating my head on a wall for over a month and spending over $300 for cables, adapters and switches, I finally found the route of the issue myself through Internet searches. Even though I've spoken to RCA/Thompson once concerning the original issue, I'm currently waiting for a response to what I have since discovered. Bottom line is, this particular TV has a Native Mode of 480 resolution. I'm not holding my breath, but I'm hoping RCA/Thompson has some way to access the TV's software menu and has the ability to change this setting.

    All of a sudden the TV looks like it's in crappy 3D with a rainbow spectrum all around the pictures.

RCA HDTV floormodel, model # : HD52w59. The picture does not come in well at all, and the menu is distorted, it seems maybe there might be a bulb out in the left side but I am not sure, how would I fix...


Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded over.

RCA HD R56WH78 projection TV, picture just got ascew,


You are haveing form the sounds of it convergence problems. I see this all the time on this set at the shop. FIrst question in customer menu under setup do you have the convergence option if not consult the tips and tricks section under fl231 problem. if you do have this you may have other troubles the convergence is controled by three seprate boards.
