43fdx15b Hitachi 42in red vertical lines magic focus inop for red


This is a convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors.Shops usually charge from $200-$300

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

I have 46ux13k hitachi tv and i need to know if there is atrick to adjusting the convergence.


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).

Then 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:

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.

Thin red line down the middle of screen


Enter muye 1 / 8 /3
it puts you into convergence mode and clears out all bad magic foces data.
then run perfect focus to save new data.

Magic focus


you need to replace the convergence Ics thats why youre unable to align the blue. If youd like me to post a link where you can get replacement ICs as well as free tech support and instructions let me know and I will post the link.

Colors all messed up


The fact that you used the term "magic focus" tells me you have a Hitachi projection set. When the colors no longer line up on a Hitachi projection TV, it means that most likely one of the convergence output IC's has shorted out. Sometimes a shorted convergence output IC will burn up a low value resistor too. I have also seen a convergence IC crack loose from the board and burn up 3 low-value resistors. If your set is using the STK392-110 IC's, it is probably a good idea to go ahead and replace both IC's with the newer upgraded STK392-150 IC's. The output IC's should be resoldered / replaced and the circuits checked and realigned by a qualified tech familiar with Hitachi projection sets.
