If picture looks 3d in some way you have a convergence problem.

This set should use two of the STK-392-150 CHIPS FOR THIS.

The repair can be a do it yourself one if you have some skill. Magic focus only attempts to adjust at about 18 points on the screen.

Parts cost will be under 25 dollars. The repair consists of getting at the chips (2) and replacing both--on EBAY they will cost under 15 dollars (I fix sets and use a seller there).

If I can help make a comment here and if this told you something you did not know, rate this solution as very helpful as I do this here for free.

SOURCE: Magic Focus does not work.

Convergence issues usually resolved by changing convergence output amplifier IC's.....Original STK392-110 should be replaced
with upgrade Stk394-160E Hitachi part # CZ 01341,change both
for reliability.....check B+ feed resistors for over-heating....T.

you need to replace the convergence ICs they are STK392-110 you can get replacements at the following link and they send instalation instructions with pictures so you can do the repair yourself. You need to replace both IC they are both STK392-110 they are located on the large heat sink on the far right side of your Tvs' chassis Heres the link for replacement ICs

SOURCE: hitachi tv magic focus does not work

Your problem is the convergence circuit. This is very common in CRT projection sets like yours. There are a couple of IC's that need to be changed and possibly some resistors. A good repair shop will run you $400-$500 to do the repair.

SOURCE: Colors are not aligned Magic focus ?

The magic focus will stop if there is a bad sensor and or a problem in the convergence circuit.

This set uses two STK-392-110 convergence chips--both along with any of the resistors that protect them need to be replaced and the set adjusted--I have repaired hundreds of these sets----


Confirm model number----and if you go into the customer menu and either red or blue will not move in any or some direction--the chips have to be replaced---LET ME KNOW WHAT YOU FIND AND I CAN GIVE YOU FAIRLY DETAILED INSTRUCTIONS ON WHERE TO GET THE PARTS AND WHAT IS INVOLVED IN THIS REPAIR.

I am here to help people--

Adjust the color in a hitachi 43F300


The below convergence procedure was copied from: http://www.espnhd.com/voice/showthread.php?t=3736

Manual Convergence for the Hitachi
1) Receive an NTSC signal.
2) Press Magic Focus to begin magic focus
3) Press magic focus again during the magic focus process to get the ?stop? screen
4) While stop screen is up, press STATUS or INFO on the remote control (R/C) to bring you to DCAM mode and
the service grid (64 point grid)
5) When you first get in here? I believe red is the selected color by default (it is flashing).
6) To choose other colors to converge, use the following buttons on the R/C:
a) ?STATUS? - Green
b) ?0? - Red
c) ?ANT? - Blue
7) Start from the center of the screen and work your way out on one color at a time. I adjusted red across the
whole screen to match green. Then I switched to blue, and adjusted that to green as well. After you adjust blue, you
may want to go back and adjust some red again? etc. until the convergence looks good.
(a) Use 4, 6, 2, and 5 on the R/C to move the cursor position(dotted lines).
(b) Use thumb stick to move the convergence point color.
** There have been other posts in here to tape together the color filters found in the Avia DVD to help converge
lines more easily. I have used this method, and it works well for adjusting to a greater detail. Basically, you put the
red filter next to the green and adjust your red to the green line both horizontally, and then vertically. Then you do
the same with the blue next to the green. Some people recommended you should be at normal viewing distance. I
did mine from just a few feet back from the set. Maybe my eyes aren?t as good? maybe I just felt like it worked
better this way. There are some other posts also recommending using binoculars. I think it?s great that people
suggest things to make the process easier? but my girlfriend would think I was insane if she saw me with
binoculars on the couch adjusting the convergence. I don?t know? whatever works best I guess.
8) I did not adjust the green at all. I use the green as the guide and did not adjust the location of any green point.
This is highly suggested unless you have geometry problems.
9) When going along the lines and adjusting, you may run into the problem of getting an ?S? curve on the line.
You?ll know if you get there. Basically, no matter what you do to adjust the line to be converged, the middle of the
line between the points will not straighten out (it bends between the points). To fix this, the manual recommends
going to the (7x5) mode which gives you less points to adjust. I had this problem, and the solution worked. There is
also another mode (3x3) which gives you even less points. Basically, if the set looks good, you only fine tune it in
(13x9) mode (64 point). If you have serious problems, the grids work as:
3x3 - ?coarse?
7x5 - ?medium?
13x9 - ?fine?
10) To get to each of these patterns use the following on the R/C: (only if you need to)
1. (3x3) Press ?STATUS? 5 times (only works when DCU is in uncorrected state)
2. (7x5) Press ?0? 5 times
3. (13x9) Press ?ANT? 5 times
11) If you adjust the 3x3, then you should go to the 7x5, and then the 13x9. You get the point? depending on where
you start, work your way up, and always finish on the 13x9
12) When finishing up the 13x9 mode, to get additional ?grids? on the edges of the screen, press the PIP CH button
on the remote control while in the digital convergence adjustment mode (DCAM). Fine tune the edge convergence
as necessary. To exit, press PIP CH again.
13) When convergence is acceptable, press PIP MODE to write data to ROM memory. ROM WRITE? is displayed
to alarm system that ROM will be overwritten with new data. Press the PIP MODE button again to write
displayed data to ROM.
14) DATA WRITE TO ROM will take approximately 4 seconds and no picture will be displayed.
15) Green dots will be displayed when operation is completed.
WARNING: YOU MUST DO THE FOLLOWING STEPS TO COMPLETE MAGIC FOCUS
INITIALIZATION!!! THERE HAVE BEEN MANY POSTS THAT PEOPLE HAVE HAD PROBLEMS
WITHOUT DOING THIS STEP BECAUSE THEY LOOSE MAGIC FOCUS!
16) Press MUTE to return to convergence pattern, then confirm again convergence is acceptable.
17) Press PIP MODE and then PIP CH to initialize Magic Focus. The initialize operation starts and several
windows appear during this operation. It takes about 30 seconds or less.
18) When green dots appear, initialize operation is finished.
19) Turn power OFF.
21) Wait a few seconds. Turn the TV on, and you should have your normal signal. Press Magic Focus button just
to make sure the magic focus still works (and that you did the last few steps properly)

Hope this helps

Manual Convergence for the Hitachi. YOU WILL NEED ORIGINAL HITACHI REMOTE. NONE ELSE WILL DO
1. Receive an NTSC signal.
2. Press Magic Focus to begin magic focus
3. Press magic focus again during the magic focus process to get the “stop” screen.
4. While stop screen is up, press STATUS or INFO on the remote control (R/C) to bring you to DCAM mode and the service grid (64 point grid).
5. When you first get in here? I believe red is the selected color by default (it is flashing).
6. To choose other colors to converge, use the following buttons on the R/C:
· “STATUS” - Green
· “0” - Red
· “ANT” – Blue

ONE COLOR WILL NOT MOVE. YOU WILL NEED TO MOVE OTHER COLORS TO ALIGN TO IT.
7. Start from the center of the screen and work your way out on one color at a time. I adjusted red across the whole screen to match green. Then I switched to blue, and adjusted that to green as well. After you adjust blue, you
may want to go back and adjust some red again? etc. until the convergence looks good.

· Use 4, 6, 2, and 5 on the R/C to move the cursor position (dotted lines).
· Use thumb stick to move the convergence point color.

11) If you adjust the 3x3, then you should go to the 7x5, and then the 13x9. You get the point… depending on where you start, work your way up, and always finish on the 13x9

Ok, I would suggest before you buy anything from anybody is to try to do a manual convergence.
