Rca hd52w59 3d color at first now just lines when it does come on

The color was 3d and now the tv will come on occasionally but mostly just show 3 fish eye lines or not come on. will the convergence fix kit solve the problem?

CA CTC111C: "adjust the center set of magnets to converge blue to green at the center of the screen. Adjust the rear set of magnets to converge red to green at the center of the screen." Your set may have a slightly different procedure. Dynamic convergence adjusts for coincidence at the edges and corners.
On old tube, hybrid, and early solid state TVs, dynamic convergence was accomplished with electronic adjustments of which there may have been a dozen or more that were not independent. With modern sets, all convergence is done with magnet rings on the neck of the CRT, magnets glued to the CRT, and by tilting the deflection yoke. The clamp in conjunction with rubber wedges or set screws assures that the yoke remains in position.
From the Sams' for the RCA CTC111C: "Loosen the screws at the 6 o'clock and 10 o'clock positions to permit the yoke to be tilted vertically. Rock yoke up and down to converge the right and left sides of the screen. Tighten screw at 6 o'clock and loosen screw at 3 o'clock to permit the yoke to be tilted horizontally. Rock yoke from side to side to converge the top and bottom of the screen. Tighten screws at 3 o'clock and 10 o'clock."
Many sets simply use the main clamp which locks the yoke to the neck of the CRT in conjunction with rubber wedges between the yoke and the funnel of the CRT to stabilize the yoke position position.
Refer to your service manual. (Is this beginning to sound repetitious?)
For additional comments on convergence adjustments, see the sections: "Tony's notes on setting convergence on delta gun CRTs" and "Saga and General setup for large CRT TVs".

    Before you go and buy parts it might be worth your time to check the
    convergence power supply fuse. It's located in the back of the TV just
    to the right of a large black component with 2 red wires coming off of
    the top. This is the flyback transformer. Just to the right of the
    flyback you should see three fuseable links that look like chicklet's
    gum. The one that may have fried is the one in the middle, it's a 400mA
    125V fuseable link.

    The convergence of the three color guns is
    controlled by a pair (sometimes three) convergence ICs (integrated
    circuits). You can't miss these if you look inside your TV. They are
    huge and mounted to big heat sinks.
    What normally happens is they fail due to heat, sometimes at the joints, and take a few other components with it.
    To have this repaired by a pro will likely run you $250-$400.
    You
    can do it yourself for about $50 in parts and a couple of hours of
    labor. I should be able to provide the part numbers and you can go for
    it if you feel adventurous and have access to some basic tools and a soldering iron.

    The convergence circuit is having problems. Since this seemed to
    "repair" itself on occassion, I'd first look for bad connections on the
    convergence ICs. These are large black ICs attached to a heatsink.
    They will have 15 pins or so. Resolder all of these pins

  • mohammed marika thambi

    This is a convergence problem and is either bad connections at teh
    convergence ICs or defective ICs. These ICs are large black Ics
    attached to a heatsink and should be marked STKxxx. Try resoldering
    the pins on these ICs first. If that fils to correct the problem,
    replace the ICs.

    It has failed and needs repaired. There are two Integrated Circuits
    needing replacement. The cost is always around $300 to $400. It is a
    common problem with big screen sets like yours.



    You can repair it by yourself if you have electronics training and
    experience. It requires knowing how to remove the ICs and soldering in
    the new ones.



    You can google around and find step by step instructions on how to do it for most models

  • mohammed marika thambi
    mohammed marika thambi Jul 04, 2009

    Well, first do the hard reset and whacking test just to make sure it is not something simple:



    ONE: Unplug the power cord for 4 hours. When you power it back up all the internal soft codes will restore to factory defaults.



    TWO: Whack the set with your hand all about; top, back, sides, etc.
    This will get any loose connection or cold solder joint to connect
    again and maybe bring it back to normal.



    If these two procedures don't help, then you can assume the problem is
    a serious one and that strong technical support will be necessary. I
    would say there are two problems acting up. 1) something in the
    deflection system and 2) a vetical blanking function that is operating
    at too high a frequency. Unfortunately, it is not something that you
    can diagnose at the home remedy level; it will require a tech who knows
    how to work on this model.

Yes, this is surely a convergence problem. The convergence kit must solve it. Quite a common prob with most of the projection TVs.

    If you go into setup then convergence. then can you move
    crosshairs in setup. Since you have a blurry picture this indicates convergence
    power supply problems....in which has to be replaced or repaired,

    If you do NOT have the Convergence in menu, it could be a special
    small fuse.


    Look next to Flyback Transfomer thier is 3
    small looks like square brown caps they are fuses FL231 one of them is opened
    causing lost of convergences, when you go to menu and do not see convergence on
    that menu this is what causes it and will set off a convergence problem.

    Thank you!
