Rear projection TV picture problem

Recently our screen is out of focus. You can see green & pink colors. Are the projectors out of alignment? I have made an appointment with a tech in two weeks. What should something like this cost to repair. TV is only 3 1/2 years old. Brand; SONY 57" Rear projection. Thank you!

I have some picture distortion - pink fuzzy color where white should be (like on hockey ice). I'm trying to determine if the t-con board is to blame and if I might fix it easily


Hi Bill.

I don't see a specific model for your TV, but have owned a rear projector system before. There is usually a sub-menu where you can do fine alignment of the Red, Green, and Blue projectors to get rid of the pink fringe. There is generally a white crosshair at center screen where you can fine align the three colors to get rid of the fringing, and sometimes an advanced menu where there are crosses all over the screen that you can individually select and fine tune, (tweaking the different optical distortions of the individual projectors to overlap).

If the fringe is a big swath instead of a fine edge, or if a color is totally gone, then you may be talking power amp issues. For fine fringes, the adjustments usually work fine.

Hoping that helps!

Picture is bowed inward and looks like a 3d image without the glasses. I also have a green, red, and blue line curving across the top of the picture.


Looks like the focusing lens may have moved a bit or the projector lamp has gone weak. Get a technician to check up the projector.

There's very little you can do here.

My zenith big screen tv is out of focus and we cant find any master focus control. How do we fix the focus?


It is unusual for a rear projection to be out of focus since the projectors are fixed. But, it is common for the projectors to be out of alignment, in which case the picture will look like a bad 3D movie of yesteryear.

Go to the setup options / menu, look for the ALIGN option, follow instructions on screen.

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the lance..it's something else..don't know what..do you?


Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html

Picture is doubled and color has pink tint


The inherent problem with rear projection TV's.

It sounds like the projectors need balanced (or a lamp is failing) and aligned. The alignment can inadvertently be changed when the TV is moved, and seldom "just happens".

Any decent TV repairman can perform the required service. I would shop locally for one.
