Color video rear projector...........color red is misaligned

KP-43T70 is a CRT based rear projector and does not use a Lamp like newer LCD/DLP projectors. It uses 3 (Red, Green, Blue) glycol liquid cooled CRT's (like the picture tubes of yesteryear) to produce the image/light as opposed to a Lamp.

While the set is prone to bad tubes a double or 3d like image is convergence--this model uses two of the STK-392-560 CHIPS for this.

Go into customer menu and call up convergence--if off and will not adjust in any area of the screen the chips are bad.

Sounds like the Blue CRT has an issue which is very common problem for that model. I wouls try replacing the Blue CRT assembly.

Oh, yea - another misaligned projection TV. All rear projection TV's seem to eventually get this disease.
Fix: perform a "convergence," which will converge all 3 color projectors to the same point.

BOTH OF THE STK-392-560 convergence chips need to be replaced; there are also fuses on the power board that protect them--do not look like fuses; if you need photos of the place where the chips are and the fuses, let me know.

Repair takes about a hour and parts if purchased on EBAY will be under 25 dollars.

possible crt problem, they have to be reseated, if not then the convergence is failing expect to pay around $300-350

no this is a capasator problem...and they will need replaced.I hope this helps!

get the tv degaused that should fix the problem

The model number is KP-53HS30, the screen is blurry displayin colors of red green pink
