It sounds like your convergence chip needs to be replaced.

I had the same thing happen to my 51" sony rear projection.

If you are good at soldering you can do it yourself. Repair kits can be found at:

How do I get rid of a double picture?


If picture is 3d etc the two stk-392-110 convergence chips need to be replaced--sometimes there will also be a 2.2 ohm resistor blue in color that is white in middle(gone).

Not a hard repair if you can solder---TV parts .com sells kits for this by brand/model numbers.

Double lettering on red when in 1080i good picture in 480p


This is a common problem. Your convergence has gone out.

Common symptoms are...

1) 3D Video
2) Warped Video
3) Convergence menu does not adjust the red or blue correctly.

PT-47WX, Blue streaks across the screen?


It is not a bulb. It is a picture tube. If there are thin blue lines across the entire screen, not just the edges, and the picture itself looks too blue, it means that the blue picture tube is being driven too hard. This could be because the blue screen voltage is too high, the boost voltage on the blue picture tube is too low, or the video output is leaky or shorted. If the picture has what looks like blue arcs and double images on one or more sides of the picture, it means that one of your convergence IC's has burned out and needs to be replaced. These are things that should be tested and serviced by a qualified tech, so allow an experienced tech to handle it for you.
