Question about Sony KP-57WS520 57" Rear Projection HDTV-Ready Television

Sony kp-43ht20 geometry issue.

I'm having problems adjusting the geometry with my t.v. I know how to get into the convergence mode and get to the color area. I just can't figure out how to move the rainbow lines to straight in green mode to make my pattern. I can get the cursor to move around the screen just unable to straighten the lines. Any help would be appreciated.

You may be setting your self up for a major headache. Trying to set convergence requires a professional pattern generator. There are also multiple phase adjustments to prevent linear drift of settings. Please spare yourself, take unit to a professional service!

I have a sony projection tv kp-43ht20 and the picture has gone pink. Can you give me an idea what has happened? Is this a fixable problem? I can't afford a brand new tv at this time. Thank you for your...

Sounds like the convergence is out of adjustment....moving the set can cause this as well as components chaging value with age....The kp43ht20 is an older set and may not have the alignment setup in the menu as with the newer sets...but you can go thru the menu to find out...if there is one, then you can try to align the convergence...usually there will be a crosshatch on the tv...when aligning convergence there will be a blue setting and a red want to select red first and try to get the lines lined up as close together as possible on the red adjustment..then you go to the blue adjustment and do the same...the outcome should be as close as possible to white when everything is lined up properly

Kp-43ht20 sony projection convergence issue with RGB

There should be a setting in your menu to adjust the convergence. if you have no luck correcting it this way you will need to have a repair center look at it.

My KP-46WT510 picture is out of alignment. There is no conversion of the red, blue and green pictures on the screen. They're off by about an inch of each other.
Some tech told me that it was the power control that was bad. I can see the picture, just very blurred.
Is he right? The tv was not move at all before this started happening.
