Question about Hitachi 53SBX01B 53" Rear Projection Television

1 Answer

Convergence problem. I have a Hitachi 53sbx10b and have a convergence problem. The picture pulls in from the top and bottom and the colors don't converge. Auto focus does not finish. If I unplug it and plug it back in it works fine for a day or two but, then have same problem. Is this fixable? I have only had the tv for 2 years.

    Could you tell me if it is worth the expense to have it fixed? Thanks for your help!

This sounds like one of your convergence IC's has burned out or its solder joints have cracked loose. Sometimes when this happens it burns up one or more of the 3 low-value resistors next to it. This should be repaired and realigned by someone with experience.

    When I do a housecall and replace a convergence IC and realign the set I charge $150, but I have heard of other shops charging as much as $400 or more. Call around and see what shops in your area charge, unless you are in north / central NJ - call me!

I have a 65 inch Hitachi projection TV and all of a sudden lines apperaed on the screen that runs across the upper part of screen. I tried using the"Magic Focus" setting to get rid of these lines...

The tv Magic Focus button don't solved these R,G,B colors lines mis alignments problems.Mean ur tv have a convergence pictures problems,it is dead.Ur tv now have any colors lines like R,G,B mis alignments,have a colors shadows picture or a 3D pictures look alike?Yes,mean ur tv convergence board it is dead to causes all of these pictures problems.The tv convergence board must have to repair like replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.The tvs shops will cost u like $300-350 for parts and labors.

I have a Hitachi 53UWX10BA tv. The picture colors are off and blurry. I ran magic focus and it showed a 4 on the bottom of the screen

The magic focus does'nt seem to reset the auto convergence on the tv. Do you have any sugestions

The Magic focus button,not in effective anymore.The tv is 100% have convergence problems,it dead.The tv colors lines R,G,B mis alignment,have colors shadows pictures or 3D pictures look alike.The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must replaced these parts on the tv convergence board to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

The top of the screen is yellow color then drops down in a swoop and more yellow and blue. otherwise picture is good, pushed the magic focus but it did no good. thanks for any help

Hitachi 53SBX10B-color and horizontal lines issues

with the original Hitachi remote go into the customer menu and select convergence---you should get a cross in the middle of the screen--look to see which color will not move either up and down or left and right---sounds like bad convergence IC and this is not uncommon in most rear projection sets---if this is the problem the set uses two convergence output IC chips that both should be replaced and then the set adjusted in the Technical menu----the convergence mode can be engaged by removing the front grill and an inspection plate behind it and pushing a small micro switch located on the front of the board; when the switch is engaged with the set turned on a grid of lines will appear on the screen and then the set is adjusted with the remote---hope this was helpful---if you need direct assistance you can contact me : [email protected]


You will need to replace both convergence Ics and the six convergence resistors. Please respond to this same post and verify the model number of your set and I will post the correct ICs and resistors for your model, as well as where to get replacements with free instructions

Hitatchi 53sbx10b

Do not adjust any knobs as instucted in the previous thread if you TV have a convergence problem. Doing so will only make things worse. The blog does however show you how to fix other common problems with these sets.

Here are some of the most common symptoms and example photos of a convergence problem

  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here is a quick test....

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

Try to adjust the red and then the blue 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.

You need to replace the convergence chips and convergence resistors. Check the site They have put together a kits for most models. If you don't see a kit for your set send them a quick note and they will put one together for you. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, etc.

Double focused, red and green, bow in picture top and bottom

You have a convergence problem
If the set has auto focus and will not complete its cycle.
The Auto focus module is bad, (expensive)
If it completes and the problem is still there.
Then check for bad conv. drivers (stk****) or cold solder joint on one or more of the 3 drivers pins.

Convergence and picture problem.

convergence ic's

Hitachi 61SDX picture got dim shows Code 3

use the advanced options page and reset the factor blue and red convergence defaults then do re apply the auto color defaults color at first it seemed very red (which is good because red was the missing factor in the green picture) but after reseting all the color and tints to the normal ranges I then reset the color auto correct again and all seems fine.
