Looks like the picture is in 3D...magic focus won't adjust green

Tried magic focus automatic...it did nothing. So tried magic focus manual. When looking at the grid, the red & blue lines line up but the green lines are way out of line. Tried to adjust but not able to.

    Same problem I am having. Worked fine one night and the next morning everything looked 3D. Tried magic focus and didn't fix problem.

  • jlegate Mar 26, 2009

    I am also having the same problem. It worked fine last night, but now the red and the blue are out of whack, and Magic Focus Manual or Auto does not fix the problem

  • jrgennari Mar 27, 2009

    I have the same problem in that the picture produces a blue shadow. Treid th emagic focus. Tried the manual focus and converged the red, green and blue (which was out). I saved the configuration and returned to the screen. Condition persists.
    I called Hitachi, who referred me to a local service repair. Spoke to them and they indicated replacing a couple of IC's and several resistors, quoting me about $350 to $400 to repair.
    Is this something I can do my self???

Sounds like the convergence chips. It's a bit intimidating to fix, but I gave it a shot and did it myself. Documented it here :

Ther is a red line on the left side of the tv the blue an green is alright but it looks like it is in 3D i have tried to line the conrv- but still nothing the red is shifted 2 inchs to the right


Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.
Here are some photos of convergence problems.

42d3683.jpg

7859b01.jpg

e87380c.jpg
Here is a quick test....

Using your original remote go-to the settings menu then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right. And you should be able to get the grid straight.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a fix

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

Hitachi 53UWX10BA dynamic convergence works but blue is blurry


I know this set very well---you are saying convergence adjusts ok everywhere? If you understand that the blue is usually de-focused a little----there are only two ways to adjust the focus of each tube-----

1.) Behind the front speaker grill there is an inspection plate---with it removed you will see a small black plastic block with 6 controls on it; it is the MASTER SCREEN/ FOCUS BLOCK

2.) THREE of the controls left to right are Screen controls(red, green and blue) and the other 3 are FOCUS--IT IS ALL black and you need to look close to identify which is focus and which is screen---you are looking for the BLUE focus control(one of the 6)

3.) With the convergence grid on screen cover the RED and GREEN lens in the set and try to adjust the focus of the blue(I presume you know how to put the set into the Convergence mode?

4.) The only other way to adjust the Blue focus is from the back of the set---with the Red and Green lens covered up place a blanket over the top of the set that covers the whole screen--from the back of the set you will note that all three of the black focal lens have a wing nut---with the convergence grid up and only blue lines present(Green and Red lens covered with a cloth) look from behind the set at the grid---loosen the wing nut on the blue lens and slowly slide the lens left or right until the blue has the best focus possible----if it will not adjust with the focal lens or the front focus control you have a circuit problem.

I do this here for free and if this information helps you take a minute and give me a vote here. If you have any questions or need advice reply to this posting here and I will assist you.

When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony, Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit from the link below.

Common Symptoms include....
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
  • TV shuts off after powering on - TV may also make a chirping noise.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

Well if you are not a repairman you should not do this kind of job yourself.
If you decide to service your TV, remember to keep it unplugged for one hour before working on it.

Hitachi 57SWX20B 3D Effect due to green light convergence problem


I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.

http://home.comcast.net/~leebailey00/Hitachi_DCAM_Manual.pdf

The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).
