There are two and sometimes three very large IC’s that control the convergence in a big screen set. They are fastened to a large heat sink because they generate a good deal of heat. Finding them is not that hard, but there is supporting electronics that will also need to be replaced during the repair. There will be fusible resistors and feedback resistors that may have been damaged at the same time.

If you choose to repair the set yourself, be very careful of the high voltage that can be stored in the capacitors, and CRT’s. This voltage can be as high as 30,000 volts.

Unless you are very handy with a soldering iron and reading color codes on the resistors. I would recommend that you have a local television service center have a look at it and get an estimate for the repair.

I don’t use the cheapest parts when I repair this circuit, because I have seen the cheap IC’s damaged as soon as power is applied. I would also recommend that when the IC’s are replaced, whoever does it, that they use plenty of heat sink compound and remove the old compound first.

I guess you are wondering how much this repair would cost.
Not knowing the labor rate in your area and diagnostic fees, I can only give you a ball park figure. I have done this repair for between $375 and $450

I hope this information allows you to resolve this issue.

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

Convergence is off


YOU DEFINITELY NEED TO CHANGE THE STK IC'S THE ONE THAT CONTROLS YOUR BLUE COLOR IS OUT BUT CHANGE BOTH THE RED AND BLUE OR ELSE IN THE NEAR FUTURE THE RED WILL BURN OUT ALSO. THESE IC'S ARE IN THE VIDEO BOARD USUALLY AND ARE ATTACHED TO AN ALUMINUM HEAT SINK. CANT MISS THEM THEY ARE PRETTY BIG AND ARE SIDE TO SIDE.

Screen prob with Hitachi 51UWX20B red square


Maybe the best way to adjust the screen is with the manual magic focus..instead of letting the tv do the auto change it to manual and see if you can adjust the convergence yourself. I have this same model and once in the manual adjustment you want to make sure you see all white lines....if you seen any blue or red that is the color that needs to be moved towards the white line closest.

Once you think you have it lined up nicely hit "exit" on your remote and option 1....

Hope this helps you.

Yellow and blue color ruins total picture on 50" tv,can't get rid


lupe0112,

I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Manual Convergence for the Hitachi. YOU WILL NEED ORIGINAL HITACH REMOTE CONTROL. 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

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.
