Question about Hitachi 53UWX10B 53" Rear Projection Television

1 Answer

Replaced IC'S and all resistors and focus problem still

The picture looks great but the small text like game scores, advertising small words and other scrolls along the top or bottom are still out of focus. Watching a football game the up close shots are perfect but the "panned out" shots you can not read jersey numbers? After converging I press the pip button to read rom and then the pip ch. button to set the majic focus and it errors out in the red as "over flow"? It looks like the color is bleeding during this. If I push the majic focus button I can get the "static mode" 9 +'s but cannot seem to get the blue to focus crisp even using the focus knobs behind the front panel. Any words of wisdom? Thank you Troy

Hello yorty,

You are the first person I have ever had to give this advice to. Let me explain, some folks "get lucky" and the replacement of the IC's and the simple alignment are usually enough, but in your case you have landed in the magical land of complete convergence adjustment.

You are going to have to perform a static and dynamic convergence alignment of your TV. in theory its very simple. here are the instructions:

First, you will have to adjust purity of the three CRTs (follow the instructions in your users guide or the schematic of your TV)

Second, you will need to set the static convergence of your TV (This will set the center of your tv and some of the side, top and bottom, lines)

Third, Once the static convergence is done you will need to set the dynamic convergence of your tv this will set the lines of the extreme top bottom and sides of your tv.

FOLLOW THE INSTRUCTIONS IN YOUR OWNERS MANUAL OR THE SCHEMATIC FOR THIS TV!!

Now for the bad news,

These three actions are all intertwined, That means that once you adjust one, you will have to readjust the others to match. Now this means that on an average, you will spend the next 8 - 16 hours doing the adjustment (8-16 hours are the estimated times for a TV technician to perform this task).

Now, I would suggest getting a TV technician to do the alignment becuase the task is very very tedious, and even most TV technicians hate doing it. I wish you well.

I hope this helps,

Thank you,

Only get red screen


Hello,

First of all Check Flash focus is working or not?(Flash focus should finish 1 full cycle)
If Flash focus not working you will have a error code in your screen.
If any error message or wont compelte full cycle you have problem with convergence amplifier IC
It could be one of your IC bad along with Couple of small Value resistor.

Dont Forget to Rate!!

Good Luck

53swx10b bowed picture


Double check your work for errors such as solder bridges or incorrect resistor placement. Look carefully anywhere solder could have dripped or splattered to cause the bowing. If you entered the digital convergence mode to touch it up, you will have to re initialize the magic focus for it to function. Good luck

Majic focus code gave me a five


Barb, thats a code for convergence error, the convergence circuit has failed, the IC`s will have to be replaced and may have 1 or 2 resistors burnt, this is not a job for a "layperson", board has to be removed, IC`s and possibly resistors un-soldered , removed and new ones re-soldered in, requires accurate voltmeter, soldering equipment and the ability to solder very small joints, I`d advise you to call a tv tech for this one, hope this helped, BMW Rider
