I have a rca d56w20byx2 and my convergence board i belive is shot. but when i pull it apart it looks like i have three diffrent boards. which one should i start with and just make sure i work on the right one what would it look like and where can i buy a new one

Re: convergence board not found
First go to menu then setup look for convergence on menu if it is not there you have a OPEN fuse FL231 it will be on right side of FBT flyback transformer there is 3 of them in a roll small brown rectangle it will be the Middle Fuse.

The tv have a problems known as a convergence problems,it is dead.Tv have any colors lines R,G,B mis alignments,have any colors shadows pictures or 3D pictures look alike?Yes,than the tv convergence board it is dead,convergence board must require changes 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to fixed the tv convergence picture problems.The tvs shops will cost u like $300-350 for parts and labors.
This is self protection on the set. Near the high voltage transformer inside the set (it is located as you look from the back on the far left and will either be black or tan--it has a large red wire coming out of the top of it) next to it are 3 tan colored coils--they look like resistors--one of them is gone----this is why convergence does not show in the menu.
One of two things wrong here---either the part just failed or THERE IS A SHORT IN THE CONVERGENCE circuit--it is spread across the circuit boards---these sets are prone to this and you will find many shops do not want to work on them.
Boards are no longer available from RCA except on a rebuild basis.
All parts are RCA only---the coils may be found at a number of sites but that board has to come out.
The coils can be tested like a fuse (which is what they are).
I have seen other techs in the shop I work for spend hours trying to get one of these sets up again.
If this told you something you did not know, rate my solution here as very helpful as I do this here for free.
On your Deflection Board it is the bottom left hand side board has FBT flyback transfomer on it Blowed Fuse FL231 it will be on right hand side of FBT there is 3 of them in a roll small brown rectrangler looking caps but they are fuses ir will be the one in the Middle Call PartStore.com 1-866-925-7278
unfotunatly the itc222 has no convergence ics it uses a series of trsansiitors. the fact that u have some areas of the screen clear may mean you need a technician to do a service alignment. when you go into setup does the convergence crosshairs move up and down and side to side on both the blue and red? if they do their may not be a problem with the power board. ONe more thing if you replace this board you will still need a technician to do a service alighnment
Convergence. very common. First question when you go into the customer menu under setup do you have the convergence option. If you do not suspect the convergence fl231 fuse problem. i hove wrote instructions under the tips and trick section. The bowed picture and line definatley indicates a loss of convergence power. There are three seprate cuircit boards that controls this convegence power, convergence amplifer and the small signal board.. the small signal board would have to be replaced by tech. as there is special equipment requird. the other two you can do. If you have convergence option try the autoconvergence option and watch to see what it does
since two colors are affected I would suggest checking the solder on the convergence power supply. If the solder is good you will most likely need a new power supply. The power supply board is the one without all the heatsinks next to the convergence board
Your set has a repair issue with the convergence circuit.
Adjustments in the service menu will not help.............I agree
with Guest comment.... circuit board repair or replacement is
what you both need.....................T.
convergence is tricky.. there are three seprate boards that it is split with.. do you have NO convergece at all.. could be convergence power board...one color... convergence amplifer board.. it it could be the signal board.. there's even a chance it could be a descrete fuse... shoot me some more info..
just found the problem fuse that causes this to happen. The set I have
also was not converging, and the auto convergences option was also
gone. The small fuse labeled fl231 which is right next to the big
plastic piece with the large red wire coming from it in the left corner
of the circuit board closest to the back. It is the middle
of the 3 small fuses that are smaller than a Chiclets gum. I was
able to pull up the circuit board and jump the fuse with some alligator
clips and the set looked great again. Every one says watch out for the
unit with that red wire SO WATCH OUT!
damortch check out mouser.com I think I found them on there gonna call them tomorrow to see if I can get mine there.
