Auto focus button was pushed a few times and now our Apex TV won't focus at all.


likely a convergence failure. if you push the button over and over, sometimes it will throw the set out so far that it cannot align anymore.. the sensors need to see the lines to do the auto alignment. you probably need new convergence ICs, repair is tricky and requires soldering. estimate = 200-350 $

My Tv has red light (color) out of focus..I've tried tuning the lance but it's not the problem in the lance..it's something else..don't know what..do you?


Your TV has three picture tubes which are aligned to properly converge the projected light beams on the screen. Each picture tube projects a single color of Blue Green or Red. During production your TV was carefully adjusted to properly align these colors. As a feature you have the ability to adjust these colors.thats called convergence.If you don't have a manual to show you how to adjust you can find one here http://www.mitsubishi-tv.com/support.html

HATACHI IS OUT OF FOCUS


This can be a number for things. Believe it or not dust or cig smoke in LCD and pix tube projected TVs turns up looking a lot like focus error. Is the focus bad or do you have a convergence error (red, blue or green shading) Is there any smearing or blooming to the pix? The other comment for you is the TV is 9 years old I personally consider this very close to the life of the product. A simple good pix would tell volumns for someone like me (may need some resolution on the pix).

Will not show red color in picture, magic focus shows red though


You have a projection light element out. I had the green element go on mine. I had a service agreement so a repair tech changed it.
