    Same with DCAM

  • Barbara Waxer Apr 23, 2013

    History: Had major convergence issues, replaced the chips, but no resistors as they looked fine. Afterward, display looked perfect, could access Magic Focus & DCAM fine. That lasted about a day. Then blue started to warp. Disassembled to ensure soldering was good, when I reassembled I could not longer access DCAM or Magic Focus. When I pressed respective buttons, the alignment screen would flash on upon button release, but not stay on. Update: can access Magic Focus, blue still off on on top row. Still can't get DCAM screen to stay on. Note: If the suggestion is to replace the blue resistors, will need help IDing which ones in the new kit.

it sounds like your blue convergence ic is getting weak you need to replace the ic's STK392-110 and you should replace both because when 1 is bad the other will go real soon. They are inexspensive at the sight I posted and you will also get free tech online support if you purchase them there.

SOURCE: hitachi tv magic focus does not work

Your problem is the convergence circuit. This is very common in CRT projection sets like yours. There are a couple of IC's that need to be changed and possibly some resistors. A good repair shop will run you $400-$500 to do the repair.

Replace Both of your STK ICs they are your convergence ics they are big black ICs will have Part# on them for example STK392-110, if they are 110s use 180s, if 020s use 040s other wise replace with exact same number. To get Parts call Electronix 1-800-223-3205

SOURCE: convergence settings on hitachi 53uwx10b

Yes - You will need to either remove the circuit board or lift up the tray. If you are not sure how to do it yourself read the link below.

  • This is a very common failure on Projection TV sets.
  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
You can see some example photos and find a solution here...

How do i adjust the magic focus?


  • Press "Menu" on the remote select the "Magic Focus" option in the Video menu or press the "Magic Focus" button on the front panel to adjust the convergence of the three picture tubes that create the proper color for the picture. Pressing the button on the TV initiates the automatic adjustment, and accessing the feature through the Video menu allows you to choose automatic or manual adjustment, though the "Automatic" setting must be selected for the button on the front of the TV to begin the process.

    Unless the CRT gnomes got in there and messed with the FACTORY SET focus adjusment then don't touch them. you'll only make it worse, you need to have the convergence board rebuilt and it should work fine.

    I get a split up of red and green in a wave at top of screen


    The convergence ICs and resistors are the most likely things to cause that. You can get the convergence repair kit for the DP14G hitachi( 53UXX10B) at the following link which contains the parts and instructions.

    HITACHI DIGITAL ULTRAVSION HDTV PROJECTION TV


    This is a problem with the convergence circuit. If you can solder, try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These ICs are large and black, attached to a heat sink and are marked STKxxx.

    Keep us posted on your progress.

    Hitachi 53UWX10B 53 convergence color lines dont move w\RC


    After replacing IC's, double check the solder connections for bridging or no solder on pin(s). Check all bias resistors (low ohmage). Make sure you have your VCC voltage, should have a positive/negitive voltage of about 24 v on each IC and +38v.Also, make sure all cables are plugged in and fully seated

    Note: All bias resistors are very low ohms eg; 3.3, 1.8, 2.2 make sure correct value, very important.
    If can't adjust still CPU digital convergence board (near ic's) shielded may be defective.
