A friend gave me a hitachi tv with no remote. I can't find a replacment remote anywhere. It also has red blue and green line going through the tv from left ot right was is the cause of that? The model # is 43FWX20B.

Not all universal remote control's operate MENU button on TV!!!
If you have >>COLOR separation ( red blue green) and CAN NOT adjust via MENU button then you must replace conversion IC's>>
part number: STK 392-xxx.....easy repair!!

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the TV 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 from the link below.

Common Symptoms include....

• 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.
• TV shuts off after powering on - TV may also make a chirping noise.

Here are some photos of convergence problems.





Here is a quick test....

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

Try to adjust the red and then the blue convergence.

You should be able to move RED and BLUE in all directions - up, down, left, and right.

If you can't move them in all directions or cant move them far enough your convergence chips are bad and should be replaced. This is a common problem.

Note: If you TV has as flash focus or magic focus button only try pressing the button. If it fails to fix the convergence your need to fix it. See below for a solution

CONVERGENCE SOLUTION

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses.
This is a a fairly easy DIY job if you know what you are doing. If you have never done this before we would advise calling a shop or if you want to do it yourself get a complete kit with instructions and support from www.TvRepairKits.com

The convergence board is on the fritz! See TVRepairKits.com and see if they have a kit just right for you!

replace the red and, blue crt fuses

HELLO MY FRIEND. YOU PROBLEM IS THE CONVERGENCE STKS, WHEN THIS IC'S ARE BAD YOU HAVE NO CONTROL OF THE CONVERGENCE ADJUSTMENTS BY REMOTE CONTROL,IF YOU OPEN THE SET LOOK FOR TWO BLACK PARTS WITH SAME SHAPE AND NUMBER.YOU CAN BUY THIS PARTS ON LINE AND REPLACED THEM PRETTY EASY IF YOU HAVE REPAIR SKILLS AND ALWAYS REMEMBER TO UNPLUG THE SET BEFORE YOU DO ANYTHING.
YOU WILL NEED A SOLDERING IRON, A DESOLDERING TOOL AND SOME SOLDER, YOU CAN GET ALL OF THIS THINGS AT RADIO SHACK.IF NOT CALL THE REPAIRMAN HE SHOULD NOT CHARGE YOU MORE THAT $250.00 FOR THIS JOB WITH PARTS INCLUDED.
GOOD LUCK

If the convergence is off more than 1/2 inch or so you can't adjust. you have a failure of hardware. most likely the output IC. This set has 2 outputs for convergence. Each output contains 3 circuits, Six circuits altogether 2 red ,2 blue and 2 green. The normal customer adjustment will only alow adjustment of blue and red. They should be converged onto the green. There is a much more complex adjustment in the service mode for Geometry and convergence. These adjustments are only needed when you replace a failed componnent like the output ic. These ICs have been upgraded several times since the production of this set. The latest and most powerfull version is STK394-160. If feel up to it I suggest changing both outputs and the corresponding output resistors. Then do a complete geometry and convergence alignment.

This is "NOT" meant as "expert" advice...as this is not my area...HOWEVER...I see no one has answered this yet...AND I got some good help from here a year or so ago that worked for me!

When I had a similar "green screen" problem with my SONY projection tv...the guy helped me by having me make "MINOR" adjustments to the red/blue/green etc knobs behind the panel. These were three small black plastic pieces and needed less than a 1/16 of an inch adjustment...try adjusting one at a time and giving it few seconds after each adjustment. It worked for me..at least for a while (till my wife gave it away to a friend because it was "too big"...ah! women!!! LOL)...hope this helps. (NON-expert help!)

Good Day;
Suspect Convergence IC's STK4274, part Number 2003191. Replace all three IK04(red), IK05(green), IK06(blue).
Good Luck, big IRISH.

Hitachi remote part # HL01643........I like the original remote
to do adjustments.................T.

I would change both ICs STK392-110 and also the 3.3ohm 1 watt resistors and the 1.8 ohm 1 watt you would need 2 of each resistor. Then your convergence would be new again. You can get replacement ICs and resistors at the following link with free shipping and free instalation instructions with pictures.
