IF you go into the customer menu and select convergence look to see if red or blue are skewed and or will not adjust.

If this is the case you have a CONVERGENCE circuit problem.

kp51hw40 uses a pair of the STK-392-560 convergence chips.

If you or someone you know can do the repair you can save the set and a lot of money--most shops get at least 300 for this repair----considering you can buy the chips and everything else you might need for under 30 dollars on Ebay (I know a good seller there)
it makes more sense if you can do it yourself.

I can give you general instructions for this repair as I have done hundreds of them---I have one tomorrow identical to the kp51hw40---different models use different chips.

Getting red, blue and green halos around images


I had a similar problem with red halos around images on my Hitachi rear projection TV. The problem was that the red convergence chip burned out. I replaced that and that fixed the problem. I found several forum posts on similar symptoms and fixes for Sony rear projection TVs by searching for "Sony rear projection convergence problem." Likely you've already tried the auto-convergence function for your set, if it has that.

Double image/ out of focus with green and blue seperation


Your tv is crt-based and is out of convergence. In other words, the settings for keeping the Red, Green and Blue images aligned have drifted and must be reset. This is common with CRT projectors and CRT rear projection tvs.

Refer to your owners manual for instructions on re-aligning it.

AUSTRALIAN PARTS


the convergence board has nothing to do with tuning of tv, the convergence board put three colour gun (red, green, blue) to work with each other, else you get three image, of red , green,  blue or mixture of all as seperate image, the convergence board for american tv and Australian tv is possibly the same what you check to see the board  part number is the same you possibly need to see if the convergence board has got the memory i.c. if that is the case, you need to tune you t.v reset the channel etc good luck.
need more help let me know.
