Magic focus error Hitachi 51F500A

On my Hitachi 51'' TV the green is separated from the other colors and when we run magic focus it stops on green and then puts up a code 4. When we try to manually adjust the colors using magic focus it won't let us select the green to pull it down

Ok, you have more than 1 post for this set--this model uses two of the STK-392-110 OR 392-150 Convergence chips.

If magic focus will not adjust the picture both chips need to be replaced--about 13 dollars in parts if purchased on Ebay.

Green is not offered to be adjusted since it determines the geometry of the picture--red and blue are adjusted to it.

Let me know how much skill you have and I can tell you how to fix the set--it requires two things--getting at the chips and being able to unsolder and replace them--there may or may not also be some resistors around them that are now bad and need to be replaced.

most shops get 300 or more for this repair--total parts cost if you are able to do it yourself is under 30 dollars.

If this helped you rate this solution as I do this here for free.

My Dad is having the same problem with the same tv and has the skills to solder and unsolder the chips. Can you let me know what part of the tv they're located in or if you have a scematic?

The color on the tv is messed up the green and red i tried auto and manual magic focus but cannot move the green line on manual magic focus please help


Most likely this set has bad convergence ic's and some open resistors. This is a common problem for projection tv's. Check:
resistors RK42, RK46,
RK50, RK54, RK58, RK62
Output STKs IK04, IK05.
I hope this helps. Thanks for using fixya.
