    I have the same problem. I have red and green ghosting that is worse on
    the right side of the screen. Magic focus has no effect and ends with
    #4. I tried service mode but cannot move the red grid lines. Now I'm
    stuck with the 9 cross-hair screen. Does anyone know where to find the
    "little blue" reset button inside the 53UDX10? There doesn't appear to
    be any screws to remove the front panel as suggested for other models
    of Hitachi rear projection TVs.

Rojamon,

That #4 error is listed as "overflow," and I got a"ROM overflow" errorwhen I tried to save my adjusted convergence data.I don't know whatthat all means yet, but if I figure out my problem,I'll post backhere. I've read here and elsewhere that the out-of-focusproblem comesfrom bad resistors or amps on the convergence board. Youcan tryservice mode to adjust convergence. Press the Magic Focusbutton, andthen press it again to stop it, and then press the Statusbutton onyour remote. Here's a link to the manual convergence procedure (scroll down).

On our set (approx. 9 years old) - the Magic Focus screen keeps appearing - any idea why?


Hello,

Likely it is appearing because one of the picture tubes (there are 3, red, blue, green) has a focusing voltage that is disproportionate from the others, and is drifting.

I would think that your power supply is beginning to fail, or one of you tubes is beginning to fail.

Poss. convergence problem with Hitachi 53UDX10B Ultravision


You have convergence problem. Either bad connections on ics, ics are bad or voltages to convergence circuit are missing. There are no bulbs in this set. 3 picture tubes,red,green and blue produce a picture than when alighned(converged) correctly on top of each other gives you a color picture.When not you get the effect you are describing. Frst you can try the magic focus in the menu.

Magic focus works briefly, then the tv is out of alignment


You need to replace the convergence chips and possibly some of the convergence resistors. You can buy the parts online from various sources or you can get a complete kit with instructions from www.TvRepairKits.com

Replace the convergence Ic's with a kit that is available through your local parts distributor

You must replace all resistors in the kit
If you are not good at soldering and de- soldering have a local tv shop do it for you

Good luck

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


lupe0112,

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.

Hi, you need to replace the convergence IC`s and any burnt resistors in front of the IC`s, common with all big screen rear projection tv`s, if you attempt to do this yourself be sure to get original IC`s or your just wasting your time, and it will take you 2 hours easy, any questions email me back, BMW Rider
