Question about Hitachi 57SWX20B 57" Rear Projection Television
After working fine for a few years, yesterday upon turning on the TV,
the shows looked like they were being broadcast in 3D (my kids'
assessment). They thought their favorite cartoons were being broadcast
in 3D as part of some special 2/29/2008 Leap Day special. Pretty
creative, but wrong.
All 3 colors (red, blue, green) are working, but the green aspect of the picture is curved at the top and bottom of the screen. (I'll attach photos)
Although I've used magic focus in the past, I've never really had to. I used it magic focus this time mode which didn't work (automatic mode). I used magic focus in manual mode (and checked the owner's manual) and realized that the green is "fixed", you can only adjust the blue and red. Manual mode shows what should be a white grid of horizontal and vertical lines--they're white when all three colors are lined up on top of each other exactly. On my TV, the center horizonal line (equator) is white (all colors are lined up), and the center vertical line is white. But the green lines get progressively curved towards the edge of the screen. The vertical green lines aren't THAT bad at the edges, but the horizontal green lines are significantly and progressively curved as they are farther away from the center. If I were to manually adjust the blue and red lines to match, the TV picture would end up looking normal height on the left and right sides of the screen, and pinched (shorter) in the middle.
So I've stumbled onto this website (nice job, FixYa). I entered this basic comment to another problem with the same TV, but while I think the result will be the same (get someone to repair it), the exact problem is different, so I'm going to create a separate problem report. Here's hoping the repair is less than the value of the TV (Someone else currently listed theirs on Amazon for about $650).
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.
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).
