Hi there i replaced my hitachi 53uwx10ba convergence IC (2) stk392-120 and now it won't turn on and just flashes at the front panel 7 times, can i get some help pls

It is rare in this set but it indicates a short somewhere that is pulling voltage inside the set down---not a do it yourself repair unless you are a Technician with some basic equipment and a schematic diagram.

Have someone look at it from a repair shop or ?

Replace Both Of your convergence ICs STK392-110 they are big black IC will have part# on them Call Mats for parts 1-800-628-1118

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.

replace the convergence ICs you can get replacement ICs at the following link with free installation instructions. Use two STK392-150 ICs they are good durable ICs for your model,
Heres the link.

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

These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

hi there. sounds like a bad convergence IC. possibly a broken connection(s), parts are located on a large heatsink near the center of the main chassis, part number is STK391-110 for standard definition and STK391-570 for high definition, the location and part numbers can vary from model to model and year to year. hope this helps.good luck and be safe.

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.
