On my HD1080 Mitsubishi projection flat screen 55809 the picture is bowed on top and bottem and it look as if the projectors themselves are offset, but the picture is clearer as you come toward the center....

It could be one of two things: Either a bad solder joint or convergence IC failure.

Convergence IC failure is very common. The solution is to replace the STK chips, check fuses and the resistors next to the STK chips. Replace as necessary and re-align via the service menu. It is about a $300 repair at a tv service center. You will need the service manual if you decide to do this yourself.

Try This:
When you notice the symptons Use this simple test to verify.
Go to the users menu on the tv.
Look for the converge option probably under setup or video setting. Converge is short for convergence to align the red and blue colors to the green color.

If you cannot move the red either horizontal or vertical, then the STK chip has failed for red section.
If you cannot move the blue either horizontal or vertical, then the STK chip has failed for the blue section.

If you can move both in each direction then the problem is something else.

Note if one STK chip fails, you replace both regardless

I have a KP-51ws520 that a friend gave up on and bought a new LCD TV. About a year ago, after a power outage in our neighborhood, this tv now has noticeable streaks across the screen at all times. Is...

It depends on what the problem actually is; are the streaks colors like red or blue outlines around lettering etc?

The more you tell me the better I can help. I will post a photo or two of what convergence problems look like.
This set is also prone to another problem, on a blank video input look at the screen: you should only see Video 1 (etc) and if you see faint curved lines (red, green or blue) and or the back ground is also wrong color you have the second problem.

let me know which it is.. If this information helped you rate this solution as very helpful as I do this here for free.

Horizontal color line across the screen

Most likely a bad Vertical IC or bad connections on the vertical IC. don't continue trying it on. If you have a bad connection it could do more damage. You also could damage the CRT ( picture tube ). If you remove the cover and look at the bottom side of the PC bord with a good magnifiing glass you may see what looks like rings around the leads comming from the Vertical IC. The Vertical IC is mounted on a heat sink usually towards the front of the set looking from back. If you do see the rings around the leads try reheating with a solder iron. If this dosen't fix you most likely need a new IC.

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.
