Question about Hitachi 43FWX20B 43" Rear Projection Television

1 Answer

Color Alignment The blue color is out of alignment on my set -- a rather large blue spot is evident in the upper left corner. Magic Focus does not fix the problem, so I tried the manual focus. It takes some time to work through the manual focus grid, but looks great when finished. HOWEVER, when I turn the set off and back on the color is severely out of alignment. How do I make it retain the manual focus when the set is turned off and back on again? When this occurs, the only way to get a decent picture back is to run Magic Focus. Then the blue spot returns in the upper left corner.

Magic focus --blue and yellow sag in the upper left area of the screen

This is a problem with the convergence circuit. If you can solder, you can repair this yourself. First try and resolder the pins on the existing convergence ICs. These are large black ICs attached to a heatsink and should be marked STKxxx. If the resoldering does not resolve the problem, replace the ICs.

Turned on TV this morning and the colors were out of alignment. TV works just looks funny. Tried the magic focus and got most of the screen lined up....except the upper left hand corner where the colors...

There is a convergence output kit for this set. There are probably resistors in the convergence circuit that are starting to loose there values. If you are going to have the set worked on have them install the whole kit which includes the convergence outputs and resistors. Thanks

Philips 23PF9966/37 color problem!

Most likely you can adjust it in the Service Alignment Mode (SAM).

Press 062596 followed by the STATUS button (upper left). Navigate to "White Tone", press the right key to enter and select "Normal" mode. Set the colors:

Red = 135, Green = 128, Blue = 133.

The "Cool" and "Warm" menus are deltas from the "Normal" settings:

COOL: R -3, G -1, B 5
WARM: R 2, G -3, B -13

Press the "MENU" button to return to the main menu, then the "Power" button to turn the TV off.

Yellow and blue color ruins total picture on 50" tv,can't get rid


I'm no expert, but I think that you have a problem with the convergence of the 3 color guns. I've been working on a similar problem. As a first step, have you tried "Magic Focus?" The Magic Focus button for the Hitachi 53UDX10B is at the left of the small front panel controls that also include your RCA composite and SVideo connectors. Let the set warm up for about 20 minutes (as recommended by the user guide), and then press the Magic Focus button. When you press the Magic focus button, the set will auto align the 3 color guns. If this doesn't fix your problem, unplug the TV for at least 4 hours and try again.

Colors are separated on the top from the left to right

Probably the color convergence is off. I had a similar problem. Have you tried the magic focus button yet? That is located at left in the small front control panel. Power on TV, wait 20 min (according to user guide), then press the magic focus. If that doesn't fix the problem, you could try the service mode alignment procedure. But that's a little trickier. I don't have a link handy for that procedure right now, but will look for it if magic focus doesn't re-align your color convergence.
