Question about Hitachi 53UDX10B 53" Rear Projection Television

1 Answer

I HAVE A HITACHI PROJECTION COLOR TV. MODEL 53UWX10BA 52". I JUST MOVED THE TV BY TRAILER FROM ONE TOWN TO ANOTHER, ABOUT 25 MILES, WHEN I PLUGGED THE TV BACK IN AND HOOKED UP THE CABLES, THE PICTURE WAS PERFECT AND IN FOCUS. i USED THE MAGIC FOCUS BUTTON ON THE TV JUST IN CASE SOMETHING WENT OUT OF ALIGNMENTA. THIS WORKED FOR ABOUT 3 DAYS, THEN THE FOCUS STARTED GOING OUT. IT WOULD FADE IN AND OUT WITH 2 OR 3 COLOR IMAGES OUT OF FOCUS ON THE SCREEN. THEN IT WOULD GO BACK INTO FOCUS, THEN OUT AGAIN. NOW FOR THE LAST SEVERAL DAYS, THE BLUE AND GREEN APPEAR TO BE FOCUSED, BUT THE RED IMAGE IS ABOUT 1-2 INCHES TO THE RIGHT OF THE BLUE/GREEN. i HAVE REUSED THE MAGIC FOCUS FUNTION REPEATEDLY BY IT HAS NOT CHANGED. ANY IDEAS HOW TO REALIGN THE RE/BLU&GREEN BULBS?

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

Hitachi 53UWX10BA HDTV adjusting color


Hi, Your tv model has a small light blue color button inside for manual adjustmnet mode. You will have to remove the front covering below the screen. its just attached with velcrow. Then there will be a centre wooden pannel with the the switching box screwed to tv front with around six screws.Open this panel and look to the left corner of the chasis boards in front of a small metallic box. Thats the switch you have to press to get into manual adjustment mode. use remote to adjust the colors. once done press it again to exist. Visit www.fixurtvs.com to find out more about tv FAQs. Thanks if you found it helpful.

PROJECTION TV HITACHI ULTRAVISION COLOR CONVERGENCE PROBLEM


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.

Solution:

Your TV has a convergence problem. Here are some of the most common symptoms.

  • Screen looks 3D
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed in or warped.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence or magic focus section.

Try to adjust the convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

Its a fairly easy fix on the Hitachi sets.

You can get a repair kit that includes all the parts from www.TvRepairKits.com. The kit includes a photo instruction guide, original Sanyo STK chips, convergence resistors, etc.
Everything you need to fix it yourself.
