Screen Problem Television Set

My Rear Projection television has a shadow on the top left of the screen that is growing. It is currently about 6 inches across from left to right and tapers down the left hand side to make a triangle about 12 inches deep.

Need some more details the problem you describe could be anything from a simple convergance problem or the light tube going bad in a light engine, one problem about $80.00 to fix the other, slightly over a $1000.00

Red shadows of words on screen of projection TV


you have to go into the menue, and go under video settings, under advanced, then into convergence, when you get the white lines all over the screen, follow the directions and adjust the red so it lines back up, other wise , take the front bottom panel off the tv, look for the 6 little nobs, look at the ones on the left, they should agjust the red, thrn the top one untill the red is focused back in.

Picture shadow on rear projection Sony big screen TV


You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

You need to have the convergence IC's replaced. A repair like this should run you about 300 bucks or so. In most places.

If you have the extended warranty, use it immediately. This happened with ours after our 1 year warranty expired and found out it would cost us over $1000 to have it fixed. We've read that RCA used faulty glue that can't withstand the heat inside, causing a mirror to slowly slip over time. Our dark shadow keeps growing and growing.

RCA should have recalled this to fix it for everyone.
