Hitachi 43fwx20b.replaced both covergence chips how do you align colors

You can call in a repair shop or you can get help from www.TvRepairKits.com . It may be bad chips, wrong resistors, loose solder, etc...hard to say.

Yes, set uses two convergence chips, either STK-392-110 OR 120.

Both will need be replaced, I have photos and instructions if you tell me how much skill you have.

Let me know if I can help you, parts cost on EBAY under 20 dollars.

the convergence is an automatic adjustment. if the auto isn't working after you tell it too from user menu,then the convergence amp is not working. this requires a tech or a good hobbiest. most of these amps are just ( stk's ) chips 3 in the unit you should replace all 3 making sire there is enough heatsink compound on them.

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. 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, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links 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 - makes a chirping sound.

Problem #2

Another common problem is dull or washed out video.
Your TV may have one or more of the following symptoms....

• Dull looking picture
• White looking picture
• Halos around objects

Check all cables,replaced all cables if more than couple years old.After that the same,ur tv have one dead color gun,require service.

First have the convergence IC's replaced these are the two large black IC's mounted on an metal heat sink.

Almost any remote will work for this set if it is Hitachi--understand----if you have one of the two STK-392-120 CHIPS THAT THIS MODEL USES BAD--It will not adjust....

All of the Hitachi remotes will work but different ones use different buttons in the convergence mode--if the model is 43fwx20b it uses a Hitachi remote with the number CLU-4321UG... printed on the front of it.

If you get a different Hitachi remote let me know--I have a book from Hitachi that shows most of the remotes by number and photo and shows which buttons do what in convergence.

Let me know if you need to know how to replace the chips-----usually you can get a remote for this type of set pretty cheap on Ebay.....

Try adjusting the convergence. If it won't move see below

This sounds like convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400

Convergence out IC, STK392-160 is available in Part Store, click link to get price info.
Thanks.

Yes it is! Just take the STK # off of the IC's and order them.
