Hitachi 53uwx10b Convergence Grid Tilted A Little...

It seems the entire Convergence Grid on my TV may be tilted slightly to the left. Is there a way to manually tilt the grid to the right just a hair and then align the colors if need be? Thank you.

    Is the mechanical alignment a complicated task to do? If not, I wouldn't mind giving it a shot with the right directions on how to do it.

    Well.. then I guess I'll have to decide if I want to pursue this depending on the complexity of the directions I receive to get the job done. So I guess the question is, where do I find the "How To" instructions on how to do this task? Is this something TVRepairKits.com will have and if so, is what I'm trying to do called, "Mechanical and Eletrical Alignment of the CRT Yokes"? Thank you.

If the tilt is not that bad, I would leave it be. The reason is yes you can straighten the tilt out, but it requires a mechanical alignment to all 3 CRT's then you will have to align the convergence on all 3 as well. Please take a few moments to rate my answer. Thank you.

    The mechanical alignment involves rotating the deflection yokes on all 3 CRT's. That part is easy its the electrical alignment that gets to be tricky to do. Yes it can be done but if you don't get the electrical alignment set up correctly and memorized correctly on a Hitachi, the "Magic Focus" feature will not operate.

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.

Convergence settings on hitachi 53uwx10b


Yes - You will need to either remove the circuit board or lift up the tray. If you are not sure how to do it yourself read the link below.

  • This is a very common failure on Projection TV sets.
  • 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.
You can see some example photos and find a solution here...

Hitachi 53uwx10b Convergence


The grid (called an overlay) is put in place to fine-tune one of the colors, usually green. Once one color is adjusted perfectly, the other 2 colors are adjusted to match the first color. For example, if the convergence data is completely erased, the tech will set up the overlay and align the green using to the overlay, and then align the red to the green and then the blue to the green. If the alignment is being done after replacing the convergence IC's because one or 2 colors are slightly off in the corners, the green is usually very close to perfect and the use of the overlay is not absolutely necessary. It is pretty easy to align one color using the outer edges of the screen itself. If you do need the overlay it can be purchased from any Hitachi parts distributor such as Herman Panson, Fox or Union Electronics.

You must have the original remote to do complete convergence adjustments. Remote method: Press MAGIC FOCUS button on front panel to start the magic focus. When magic focus is running, press MAGIC FOCUS again. STOP should appear onscreen. Immediately press RECALL or STATUS on the remote (must be pressed before STOP vanishes). The set is now in DCAM (Digital Convergence Adjustment Mode). Manual method: Remove the front grill and access panel or reach around from the back and press the little pushbutton located in the front left corner of the PC board, next to the Digital Convergence Module.
Once in DCAM, the remote buttons STATUS selects green, 0 selects red and ANT selects blue. 2,4,5 and 6 move the cursor and the thumbstick makes the corrections.Make all necessary corrections and then press PIP MODE. The words ROM WRITE? appear onscreen. Press PIP MODE again to store settings. When green dots appear, press MUTE to return to convergence pattern. Press PIP MODE (ROM WRITE? appears again) and then press PIP CH. This will Initialize the internal sensor data positions. When INIT finishes, press POWER on the TV and convergence is complete.

Is it my Convergance??


Do not try to align the colors with the remote. One of your convergence IC's has gone bad and needs to be replaced, possible burning one of the 3 low value resistors next to it. If you change the convergence settings now then they will have to be reset when the new IC is installed.
