Replace the conv ICs. Sometimes it's just the soldering involved, DK on Hit. But bottom line it's usually the conv ICs. They work very hard in there.

    conv ICs means convergence ICs. They are the workhorses of the convergence circuit. If you want coaching on how to do that, I am available for phone coaching/consultation.



    DK on Hit means I Don't Know on Hitachi, as to whether they have problems that can be remedied fairly directly via resoldering of their legs at the pads in the boards they are mounted on, like is very prevalently the issue on lots of Mitsubishis. Also as to what exact ICs are used.

How do i get my hitachi 53uwx10ba into convergence mode?


This should be a menu option in the video portion or initial set up area of your menu. If you have auto converge it will do it for you otherwise it will put up a screen with color patterns for you to manually converge.

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.

Hitachi 53uwx10ba turns on & off when off red flashing light/clic


Same problem. Replaced both convergence ICs about 5 months ago. Worked fince since then and just recently no sound, no video, blinking red on front panel and clicking sound. I suspect that the ICs went bad again and blew a resistor or two. I used cheap Chinese ICs instead of the Sanyo ones and thing this is why. I'll be looking at it again and post solution.

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.
