    I have replaced convergance chips (both) I have also replaced RK42, RK46, RK50, RK54, RK58, RK62. I still have a small issue with the red, but a really bad issue with the blue. When I use the convergance button it allows me to adjust the center lines but the lines that need adjusting are on the left. Both red and blue. When I try to adjust the blue it blinks once and back to wher I started not allowing me to adjust the blue. I boogered up the chip sets when I took them out, which made it hard to create good connections on the wires. It is still having the same issue as before though. I can't understand it. Can anyone help me?

This is a problem with the convergence circuit. If you can solder, try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These ICs are large and black, attached to a heat sink and are marked STKxxx.

Keep us posted on your progress.

53 INCH HITACHI RED CONVERGENCE


This is a defect most likely on the convergence board.

You should have the manufacture authorized service people repair the set. You can end up buying a convergence board, and the service manuals, and still have some other faults.

For information and parts, look up the Hitachi home page on the net and go to their support area.

Hitachi 43FDXO1B Convergence?


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.

· 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)
