Hitachi 43FDX20B 43" Rear Projection Television Logo
Posted on Dec 19, 2008

I think its called a convergance problem. or maybe color alignmen

The color at the top and bottom are out of wack. the colors are shadowing each other or like stacked, not on top of each other like they should be. i'm a locomotive electrician and work with a lot of solid state equipment. in the military 35 years ago i worked on closed circuit color tv and used to have a color and dot generator and still have an o scope but no signal generator to signal trace.i have digital meters, and an amp probe rated high enough for the flyback transformer, hell i dont know if they even still have a flyback with no crt. i'm certainly not trying to impress you i'm just trying to say i do have some test equip and used to be quite good at this so maybe you might be willing to try this with me. sears is supposed to come out on the 6 of jan but that means my kids wife and i cant enjoy our tv over the holidays. so i guess my question is do you think we can fix it together or should i just wait until the 6th as not to make it any worse. on the tech threads it sounds as though it costs between 2 and 5 hundred dollars if you have to have a pro do a full alignment. oh yea 1 other note, i dont know if its true but my 10 year old daughter said she was just watching and the color screwed up she didnt bump the tv or something like that. this is why i feel its auto focus or magic color or electronic alignment. also if your advice is to let a pro should i just get a new tv in your opinion. specs :2002 hitachi 43fdx20b 43" rear projection tv. thank you in advance if you're able to help me. may god bless you and yours. Happy Holidays Gene Nelson

    1. any letters appear overlap

    2. Magic foucs seems to have problems with red/green and when finished the number 4 appears on bottom right.

    I have a similar problem. Magic focus gets stuck on color blue. screen goes black then number 5 in bright green appears on bottom right hand corner of the screen picture then comes back and is still overlapping and a bit fussy

Colors out of porportion, maybe a bulb went out

When you have a 3-d effect. this is called convergence. Is the picture disorted or bowed in. if the picture is bowed in then this is an indicaTION of complete loss of power to covergence curcit. I always check to see if you have the convergence option in the setup menu if you do not then i suggest reading the fl231 problem in the tips and tricks sectionl

Is it my Convergance??

Do not try to align the colors with the remote. One of your convergence IC's has gone bad and needs to be replaced, possible burning one of the 3 low value resistors next to it. If you change the convergence settings now then they will have to be reset when the new IC is installed.
