Hello,

I posted this some time ago, but it is useful to your problem so here it goes:

It sounds like you convergence amplifiers are about to malfunction. If possible can you post a picture of what is happening. Again by the description you gave it sounds like the convergence amplifiers.

If you go to a shop the cost will about $400 - $500 (includes parts and labor).
If you do it yourself the cost will be about $25.00 - $50.00 (includes parts labor is free)

If you choose to do this yourself, here are the basic instructions:
1. Unplug the TV set
2. Take the rear bottom panel off
3. look for a large heat sink with two large black ICs (STK392-110) (6 sided components but rectangular in shape) on it, and remove the board the ICs are on from the TV set.
4. Unsolder the components using a soldering iron and a suction solder remover.
5. disconnect the components (ICs) from the heat sink
6. Unsolder all of the bias resistors and replace them with the proper values (usually 220, 150, 3.3, 2.2, and 3.9 ohms)
7. install the new ICs (STK392-110)
8. solder all connections IC and bias resistors
9. Inspect for shorts
10. reinstall circuit board
11. Plug the TV set in and turn it on.

Remember to check the deflection circuits also

I hope this helps

Thank you,

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.

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.

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).
