Repair shop will charge between 4 and 500 or you can do it yourself for about 45.00. You need two STK392-110 convergence ICs you can get replacment ICs at the folowing link and they provide free instalation instructions with pictures.

Hitachi 53fdx20b has yellow line on top and bottom an well as blue, all color if off. What is the problem and how much would it cost to get fixed or can I fix it myself?

It sounds like a convergence problem and is typical for many projection sets.

Parts cost would be under 25 dollars.

The repair consists of getting at and replacing two convergence chips and being able to solder is also involved as they have 18 pins each chip.

Let me know your skill level and I would be happy to help.

Tv was working and the reds wouldnt line up good did the convergence and they were acceptable not perfect though. now the tv went black. is it worth fixing?

Maybe so. Convergence is generally controlled by two large ic's " chips" from the symptoms you describe the convergence ic or stk's as they are commonly called are possible blown. When these short generally that will lead to a shutdown. There could be additional problems as always. Cost are difficult to deternine depending on where you get your repair. If the chips are the problem they generally average about 25 to 50 apeice for the chips. Our shop generally charged about 150 to 200 for such a repair. My advice is it is cost affective to repair this set. .Note: when these ic's blown they can damage other components that might add to cost of repair.

I need to line up my colors and magic focus does not work.

If picture looks 3d in some way you have a convergence problem.

This set should use two of the STK-392-150 CHIPS FOR THIS.

The repair can be a do it yourself one if you have some skill. Magic focus only attempts to adjust at about 18 points on the screen.

Parts cost will be under 25 dollars. The repair consists of getting at the chips (2) and replacing both--on EBAY they will cost under 15 dollars (I fix sets and use a seller there).

If I can help make a comment here and if this told you something you did not know, rate this solution as very helpful as I do this here for free.

There is a blue color shift to the right making people look like they have a blue shadow. Thanks. Matt.

it is a convergence failure
you need new stk chips to fix
this is complicated and requires soldering
typical cost 150 to 300

if you are crafty i can give you ideas on how to improve the picture without repairing but you will have to reach near high voltage lines, let me know if you feel so inclined

The tv works but the picture is distorted all around the outer edges of the screen, and what you can see looks alittle blurry.

This is a convergence problem. you can try to re converge it with flash focus button on TV or in the menu if there is an option for convergence or focus. If you get into this menu and the lines will not move in all directions to line them all up you will have to replace I/C chips on convergence board inside TV. Do you know how to solder? if not this type of repair will typically cost $300 to $450 for a repair man. Let me know if this helps. Please reply to this solution if you have further questions or need assistance replacing I/C chips. I can help walk you through process if you feel comfortable with soldering and circuit boards. If you feel you can repair yourself with guidance from fixya should cost less than $50 to fix.

Ghosting and shadowing. tried adjusting the convergence red/blue but it will not adjust correctly.

Probably looks like red /green highlighting more pronounced
on the edges of the screen ,right?

The problem is one of the two convergence chips is failing.
In side the set there is a P.C. Board with two big modules (Chips)
screwed to a heat sink the prefix on the chips should read
STK or Sk followed by a number . those are the convergence
chips . They cost about 10.00 -20.00 etch and are not to hard
to remove and solder new ones in if your handy with a soldering iron.
That will fix the problem.

Or you can have a shop replace them for you
at a cost of 200.00-300.00 ouch.

They need to be replaced in pairs.

if you have any questions just comment and ill respond in kind.
