Sony kp43ht20 alignment issue?

It appears that the red image is shifted slightly from where it should be. Is there a way to align this? I have tried the align button on the tv but it does not fix it. Some times the red images flickers side to side as well.

Convergence IC likely culprit. Could be buffering caps, too, although in my experience, I'm never that lucky...accordianman

I have 3 thin lines red, green,blue at the top of the screen, from side to side and slightly arched. I tried the convergence, but it didn't help. Is this a costly repair or can it be done myself?


It is alignment problem & needs lot of patience, expertise to align LCD panels. To align slightly loosen the screws on red & blue panels. Switch on the TV with input source as computer as it has steady graphics. Align for red & blue by slightest movement using light taps with screwdriver sideways. When you are satisfied, tighten the screws. If it is one pixel height line, just neglect it. That much error can be expected.
WARNING: If you are not sure, do not carry out the alignment. Otherwise it will go more out of alignment.

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

Sony kp43ht20 has green distortion and slight double pic


These chips are the culprit:

Replacing them requires a lot of soldering and a knowledge of circuit boards.

Is the Tv worth saving? is it bright and clear? was it good (when it worked?)
if the answer to all of these is yes, then you have a few choices. If any of these are not true, then you should just get a new tv.

Your choices are:
If you are good at soldering, then you can attempt to replace the IC's yourself. (with all of the parts handy, it should take 1 hour)

If you aren't good at soldering, then you can have a friend do it for you, or you can have a mechanic fix it. (tell them that its the convergence IC's that went bad. (pay no more than $200 for the job).


These go bad on almost all projection tvs2_bing.gif eventually. They overheat and burn out, causing the screen to go in/out of alignment and make wavy lines.

If you need more info on IC's, contact me.

Thanks for asking!

the differnt guns are out of alignment. Your tv has 3 lcd screens, a red, green and blue one what overlay to form the image. Sometimes they move slightly for what ever reason and that causes the rainbow and out of focus picture. Its something that a trained pro should do but is a cheap fix and won't set you back too much

Picture out of alignment


Look in the menu for a manual alignment. From there you should be manually able to adjust each corner and overall color alignment unless other damage has occurred. Try that first.
