Greetings,
The problem you are having has to do with the internal alignment of the magnetic field of the projection lamps. Each lamp has an internal fine adjustment for the edges. Projection lamps subjected to the earths magnetic field. What this means is that the closer you are to the equator the wider the magnetic dispersion of the earth magnetic field. The effect of the earths magnetic field shows up on rear projection TV's as an alignment problem that first occurs in the corner's of your projection TV. The only way to fix this is a very complicated service prochedure that invlove a electronic alignment of each separte rear projection tube. I would not suggest you attempt this repair yourself unless you know exactly what you are doing. The best thing to do is to contact a qualified service shop that repairs your brand of TV and get a estimate. I suggest that if the cost of the repair exceeds or is close to the amount that you can buy a new plasma or LCD TV that you consider upgrading to the newer flat panels that will never have this type of problem. Flat panel also can have problems so if you decide to purchase a new set I suggest that you consider the extended service contracts that is either offered by the seller or the manufacturer. 
I hope this give you the perspective you need to consider your options.

55 inch mitsubishi rear projection tv red lamp out of adjustment


Have convergence IC's replaced. I believe this unit uses STK-392-570 convergence IC's Only one has gone bad but replace them both, because if one has failed then the other is not far behind, for Blue and Green. One handles Red, One handles BLUE and Grn. There are only two of them in the set, They are the two largest IC's in the entire set.

Screen hazzy and issue with blue convergence


bad convergence would cause show to look as if it was supposed to be a 3-d movie, if a bulb was going out then people would look purple blue -green,or some other off color, so likely the green bulb is going out from the color of the people you described.

JVC AV56-WP74 Convergence problem


Hello saduchan,

I think that your ICs are ok, What you need to perform is what is called dynamic convergence, This involves using the internal convergence controls to align the outer edges of the screen. I am assuming that the center of the screen is ok? it's just the edges which are misaligned, right? Now for the bad news, this task is not easy in fact the job takes a pro about 6 to 12 hours to do it right. I think you should have a qualified TV technician attempt the static convergence setup followed by the dynamic convergence setup.

I hope this helps,

Thank you,

51mp392h Blue Convergence Problem


Hello rogeuryder,

This is the one thing that even make TV repair persons shudder. You don't really have a convergence problem in the normal sense. The convergence works. What you have is a misaligned convergence situation which any documentation and or book on TV repair will tell you that at this point manual convergence adjustment is needed and the only thing you will have to do is keep trying to adjust the convergence until you get the center aligned, and then work towards the outer edges using both static (Center) and dynamic (outer edges) convergence techniques.

As this may sound it is; Very Very Tedious.

Here is something that may help you:

http://books.google.com/books?id=ttBofTJM7FEC&pg=PA112&lpg=PA112&dq=static+convergence&source=web&ots=hyUMeeY9s6&sig=DZm27q1aMbLiwKA__fyysBd2yUE&hl=en&sa=X&oi=book_result&resnum=9&ct=result#PPA112,M1

I have used this book when I use to teach TV repair. I hope you discover what I am tried to convey in my e-mail, this is no longer a question of can you fix a TV? It has become a question of do you have the patience to adjust a TV.

Good fortune in doing this, you will succeed if you just take your time and do static convergence first and then do the dynamic convergence with the manual controls. The procedure will be in the service manual.

I hope this helps

Thank you,
