You will need to replace bothe STK392-110 Convergence ICs and the six resistors . You will need two 3.3 ohm 1 watt metal film resistors for RK42 and RK50, then two 1.8 ohm 1 watt metal films for RK46 & RK54, then one 3.9 ohm 1watt metal film for RK58 and finally one 2.2 ohm 1watt metal film for RK62. You can get the two replacemnet ICs and the resistors at the following link and they will include fre instalation instructions with pictures so you can do the repair your self.

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

Hitachi 53udx10b 53" The focus went crazy tonight and magic focus stops at red then displays a code 3 ?


Most likely the Convergence Ic's went bad, best solution is to have a service center diagnose the problem. Normally, they charge $200.-300. depending on the parts. A good point is, that particular chassis is easy to repair for the prof.

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.

My hitachi 53udx10b tv is out of focus.


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).
