Hitachi 43FDX01B, symptoms: Top left 1/4 of the screen distorted colours (convergence) red and green and in the middle of the screen horizontally red and green half lines, Menu adjustment will not fix it. How to troubleshoot if its a CI, or something else. Any pictures, manuals, step-by-steps, links will be greatly appreciated. Or is there some kind of a menu on the tv, for troubleshooting and service. Thank you.
Convergence IC's must be changed to start repair..original...
STK392-110 sub to Hitachi upgrade STK394-160E.....PART #
CZ 01341...you need two....
Next, take a critical look at the B+ feed resistors near the IC's..
check for over-heat / damage......usually 2.2 ohm 2 watt......
Let me know....................T.

Just bought a 43FDXO1B(no remote) for $150,....the picture had a slight double image(red&green) and a green arc at the bottom. I downloaded the manual and tried adjusting the convergence from the control panel, now I have another arc at the top and more double imaging.Lines did'nt seem to adjust during convergence. I am pretty handy, but think I will call a technician to repair IC's if that is the case.Any suggestions or price ranges for repair?
Live in Detroit metro area.
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)

My TV has 2 Blue Streaks going through it (almost like an upside down blue rainbow) and has a yellowish/blue tint to the picture as well. Also the TV blinks every 10 seconds from the cable signal to a black blank screen then comes back to the cable signal. Like I said that happens about every 10 seconds. If I am watching sports and the station shows the score and time bar on the top of the screen its all distorted inside of that blue streak as well. They normal scoreboard at the top of the screen almost looks like you need 3D glasses to see it or like a shadowed font. Does anyone know what I need for parts? How much they would be and what I would need to do to fix it on my own? I've called around a few places and they are saying around $250 and $75 if they can't fix it. Please Help, Thanks for your time. -Dave
i am not sure these is going to work but give it a try. after useing the tv for a long time you can get a problem with the lineing of the three picture colors may drift away from each other causeing the problem you have, they move because of moveing the tv or the viberation of the tv. you can to one of two things if you have a remote for the tv go to the menu and look for the convergence adj. setting then you are going to get close to you tv and press the small but the says the same thing now on the screen you are going to see a grid the you can fix youself with the remote just by pressing the up, down,left, rigth buttons and the menu button to change the color, to aline the red line and blue line with the middle line till you get only a white line going up and down if the doesn't work just unplugg th power cord and what for about 4 hours and then plug it in and turn it on again. if after you do all these if you still have the problem then you either have two choices call to see how much it will cost to repair it or toss it out and get a new one

TV not picking up all my basic cable channels. I can only get about 12-16 channels. Bought TV used. No remote or owners manual;
Check the menu setting to see if it's set to antenna rather than cable.(setup menu)

HOW CAN WE CHANGE TV TO AV ON HITACHI TV WITHOUT REMOTE ?
Try this! Get into the menu and look for channel setup. See channel memory delete or save and add this to channel memory. Hope this works..I never repaired this model. This is only a suggestion.

we have the Hitachi 43FDX01B projection TV, all of a sudden we now have a constant green tint
Hi,
According to the system the problem in your projection is convergence and the solution is to replace the IC STK's.The part Number is CZ01341. Change the IC STK both and your TV work fine again.And for parts please see the link below.

ITEM: Hitachi UltraScan HD Projection Screen TV:
Problem: The green will not sync up or align with the red and blue. It looks like there is two pictures or a ghost picture of green over the main image.
Have tried: Manual Alignment using a remote; tried to move the green lines, they will not move they have a bow from left to right, from the top towards the center on the bottom as well. Tried to reset the settings to factory settings, this didn't help at all green was still bowed and the red and blue were even farther off.
Question: Do I need a new IC for the green bulb? If so what is an IC (what does IC mean?) and where is a good place to get one?
The convergence board is on the fritz! See TVRepairKits.com and see if they have a kit just right for you!
