You have a defective light engine and you do not have to be under warranty for Hitachi to replace this part. We just went through this and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. They will act like they've never heard of this problem but they have. They will give you the names of some certified dealers in your area to call. Once a tech comes out and confirms that it's the light engine, call Hitachi back and they will send a brand new light engine to the dealer and Hitachi will cover the cost of the part (cost $1500).

Here is the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty, all you pay is the install. Our install cost $400. Others on this site have paid $200. Do not let anyone tell you that you have to pay for the light engine part...you do not. Hitachi has not recalled this part but they are replacing it for free. Also, deal only with Hitachi customer realations number that I listed. Good Luck!

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

Hitachi 51F500 magic focus wont work, blue has "dropped", when I use the magic focus on auto it does nothing, when I use manual focus the grid has the blue scooped down and I can't seem to get it back in...


Sounds like your blue convergence module is faulty along with a few resistors. There is two convergence modules in your set(stk-392-020) and when one fails, the both of them are usually replaced with a matched pair .If you have a good knowledge of electronic you may replace them yourself.otherwise you`ll need the help of a tv repairman. Hope this help. Good luck

Screen prob with Hitachi 51UWX20B red square


Maybe the best way to adjust the screen is with the manual magic focus..instead of letting the tv do the auto change it to manual and see if you can adjust the convergence yourself. I have this same model and once in the manual adjustment you want to make sure you see all white lines....if you seen any blue or red that is the color that needs to be moved towards the white line closest.

Once you think you have it lined up nicely hit "exit" on your remote and option 1....

Hope this helps you.

Magic focus off


You will not be able to solve this yourself. It needs the convergence IC's replaced which is a big job.

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)

Solution:
Your TV has a convergence problem. Here are some of the most common symptoms.

Screen looks 3D
One or more colors can't be adjusted when using the convergence menu.
Screen is bowed in but stationary.
Here is a quick test....
Using your original remote go-to the tv settings then goto the convergence or magic focus section
Try to adjust the red and then the blue convergence.
You should be able to move them up, down, left, and right.
If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.
You can get a repair kit that includes all the parts from www.TvRepairKits.com.
They have put together a kit for the Hitachi TV sets.
The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself. Its a fairly easy fix on the Hitachi sets.
