Question about Sony KP-43HT20 43" Rear Projection HDTV-Ready Television

1 Answer

Blue and red color are off, picture is not clear

Hi,
I moved my KP-43HT20 TV by few inches and after turning on, found the picture to be unclear. Looks like the red has shifted right of the blue color. I used Flash Focus button few times, during various times after turning the TV on, but of no use, no improvement. Sound is great. DVD also shows the same problem. So it isn't anything to do with Dish satellite system.
Is there any solution that one can try on his own before calling in the service technicians?
Please help!
- Sunny

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 setting...you 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

Green hue on KP-43Ht20 Sony rear projection tv


Behind the front cover you will see a little plastic box with six phillips headed dials. They only move 180 degrees. The three on the bottom control color richness and the three above them control focus. Turn all three of the bottom ones to the left while the TV is on, then gradually turn them to the right until you get the color you want. NOTE if any one of the three bottom dials are too far up the TV will shut down and will continue to turn off after about 10 seconds after start up until the offending dial is turned back a little.
