    I have been out of town for a few days and not had time to address this TV issue. My additional question is, are the convergance ICs something that is a pull and plug item or will the replacement be better left to someone skilled in electronics. Additionally, If I order the parts are the repair instructions sent with the part or is there another source for that information.

    No the Convergence ICs need to be unsolderd and the new ones solderd in, and yes the instructions come with the ICs, often they email the instructions when the order is shipped so you have a chance to get famillar with the process while waiting for your parts.

Vertical position does not work on remote. Magic focus on green goes half way stops then number five comes on screen. Hitachi 51inch rear projection tv


Magic focus on a Hitachi only adjusts at 16 points on the screen and needs to be done in a dimly lit room. Frankly its a sales gimmick, the number 5 means one of the sensors inside the screen for the Magic focus is not connected or bad.

Go into the tech mode for convergence with the original remote (that menu is called the Decam mode) and see if convergence will adjust there. There are close to 120 points that can be adjusted there as opposed to less than twenty in the magic focus mode.

We cannot get the color to align. It appears like there is a blue or yellow background around words


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Here's a link to perform a DCAM convergence on your television and reset your magic focus. Instructions for the S series are halfway down but be sure to read the whole page. Best of luck.

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).
· Use thumb stick to move the convergence point color.


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:
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.
16) Press MUTE to return to convergence pattern, then confirm again convergence is acceptable.
17) Turn power OFF.
18) 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)

Sounds like a Convergence IC problem, the convergence ics would need to be replaced. This can be done by yourself or a professional.
