Question about Hitachi 60SBX78B 60" Rear Projection Television

1 Answer

PICTURE PROBLEM The video seems to go off the edge of the screen. It is difficult to see things on the edges of the screen. When I run a magic focus, it stops short and a number 4 appears in the lower right hand corner of the screen.

Hitachi 51S700 won't turn off


Some kind of a problem likely in the magic focus area--is the set showing a error on screen if you engage the magic focus?

One thing not to do is disconnect the sensors inside the screen as that could make things worse......

The colors seem out of focus. Blues and yellows don't seem to match. For instance, if I have words projected, it's like I have a blue word with a yellow shadow of the word. And there is a band of blue...


sounds like you have ghosting, this is not adjustable unless you can get into the hidden menu and then you have to know exactly what you are doing. Or the LCD ribbons have come loose. The easiest thing to try is reflashing the software.

Magic Focus error green 5.


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.

Will not show red color in picture, magic focus shows red though


You have a projection light element out. I had the green element go on mine. I had a service agreement so a repair tech changed it.

Hitachi 57SWX20B 3D Effect due to green light convergence problem


I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.

http://home.comcast.net/~leebailey00/Hitachi_DCAM_Manual.pdf

The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).

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)

Out of focus monitor - 955DF


Edge-focus is notoriously tricky on flat-screen picture tubes. I have not found anything on adjusting the focus for this model. it seems to be a common problem, though it seems to be more of a sample-defect problem rather than a poor design; a replacement should be OK.
