Question about Hitachi 43FWX20B 43" Rear Projection Television
I was reading some of the problems others were having with the picture on this tv and am having the same, I think. My picture got all distorted on the left side with green and purple colors. The Magic Focus didn't resolve the problem. I adjusted the grid in the manual mode and it is much better but there is still a purple line vertically on the left edge of the screen I can't get rid of. Should I replace the STK's and get the resistor KIT10 or just the STK's? Thanks.

You have to replace 2 IC's STK 392-120 in convergence amplifier module. If you're a good handyman you can do it by yourself, if not call a tech. Also you can find one resistor burned in the output of the IC's. Replace that too.

I'm trying to fix the issue on my 43FDX20B. So far, I'm able to move the lines up and down, but can't get the left/right motion to fix it. The attached link has the dynamic mode instructions, so you can correct this issue yourself.
The only thing I didn't have was the screen overlay jig the manual talks about. I decided to create one myself and use the screen as a beginning template. I went to our local hardware store and picked up some home window weather covering. The roll cost about $15, is a clear strong plastic and the template was very easy to create. I used a straight edge after I put dots on the plastic and measured the lines for being square and equal after I took it off my tv. Good thing is that if you don't like what you make the first time, you have a 25' roll to use to try again (ha).

blue convergence IC needs replacing. That should have 3 ICs one for each color if so you only need to replace the blue. but if it has only 2 ICs then you will need to change both. If you need further info let me know.

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.
