Convergence issue Hitachi HDTV Model #53uwx10ba

I have a Hitachi 53uwx10ba HDTV and I was checking the convergence board for any cracks or broken soder and placed it back in and hooked it back up. When i powered it back on and hit the magic focus buton on the front i get a bunch of crosshairs all misaligned and the screen just freezes. Also i have a fuzzy blank area about 2-3 inches thick in a L shape in the upper right hand corner of the screen. do i need to do a manual convergence b/f the magic focus will realign right or is it that the convergence board is shot in general and if so where is the cheapest place to find one.

    I have a convergence problem. 1/3 of the screen looks ok but 2/3
    has red colors mismatched. I have not been able to figure out how
    to do a manual convergence. I only see an option to do the magic
    focus. How do I get to the manual setting to see if I can correct.

You have a sensor problem to start magic focus is the last step in this repair done normally after replace converge outputs did you do this? if so a manual alignment is needed then you may write it into memory if you get a solid green screen after just briefly you have done it wright if you get a red screen after wards you need to try again it will stop on red if all is not well

Hitachi projection tv 53uwx10ba - the Convergence ICs were replaced. When the PDKP bridge between convergence board and 2nd board is plugged in, it makes a noise. Kept that unplugged, the picture is...


Did set have this problem before you replaced the STKS?

I know these sets very well. If problem is different in any way from before you replaced chips.......double check all soldering or one of the new chips may be defective.

The more you tell me the better I can help.

Your tv may have a small button hidden on the board. You will need to look behind the speaker panel at the circuit board. Its a small blue button located on the convergence board.

Hitachi 53UWX10BA HDTV with convergence problem for blue


No there are no quick fix options for this fault. The convergence amplifiers operate similar to a high power audio amplifier, so if there is an impairment anywhere in the system, it will result in distorted audio, or in the case of television convergence amplifiers, a color won't align. The convergence power pacs need to be replaced and the out of tolerance precision resistors located near the power pacs need to be carefully checked and replaced as necessary.

It is also possible that there are root faults that cause the amplifiers to go bad which include bad connections or a bad digital control module. This repair is possible for anyone having basic electronics knowledge and soldering skills.

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.
