RCA HD52W59 Pincussion Problem

I'm visiting the kids in remote Arizona. They have a Big Screen RCA model HD52W59 with a Pincussion Problem. It comes on within a normal warm up time with the problem big as day..... top and bottom and convergence out of wack. Is there anything I can look for...... or a board that I could take back to the Big City for repair???
Thanks

    It is a ITC222A chassis.
    The picture comes on with R G & B lines concave across the top and then at full on, the picture is concave at the top and convex at the bottom.
    Thanks for the quick response.

    Ok....as I understand, I don't have the auto convergence option in the setup menu. That means I should check fl231. If this fuse was OK, does that place the auto convergence option back into the setup menu?

    Thank you for your help. I will try this tomorrow......with care.

Is this chassis a ITC222 ? If so then, yes there are things you can look for.

    Sorry been kind of busy, I saw other mention FL231 which can be correct, but along with this I would change also DL231 and other things to check is connector BW005 to see if bowed, and also RP610 to see if open. This is a 220K ohm resistor. Try this and you should be ok, now if no luck you may need further info, you can try ctechnicians.com

    It appears to have a pincushion issue too as both the left and right sides arch upwards.
    try the service menu pin chusion settings.

    I think it has the issue with the convergence IC chips if the auto-adjustand service menu manual adjustment make no difference in the convergence of the picture.


  • dewan nafees ahmed Dec 29, 2007

    The shape your seeduring this problem is called 'V Bow' and 'Pincushion' which needs to be calibrated again.

    Theres probably a diode that went out. The tech can open it up and
    adjust the angles back. I wouldn't charge over $100-$150. Shop around
    for a good repair tech.

    if its pincushion issue or convergence.. please be clear..
    pincushion will not cost you more than 200$ for sure (if u r loacted within 40km from service person).

    for convergence issue read this forum for more info...

  • dewan nafees ahmed Dec 29, 2007

    to do convergence manually

    To adjust the convergence on your model TV:

    1. Access the main menu
    2. Arrow to SCREEN and press OK
    3. Arrow to ADJUST PROJECTION TV and press OK

    this s a convergence issue i think.. but i dono why that lines are coming..

  • dewan nafees ahmed Dec 29, 2007

    auto convergences option was also
    gone means. 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.u will be
    able to pull up the circuit board and jump the fuse with some alligator
    clips and the set will look great again.

  • dewan nafees ahmed Dec 30, 2007

    ya correct. that is what to be done.
    but do with care.
    handle safely. in even of correcting this problem dont mess up other things.

That model is famous for having capacitor issue and bad flybacks both items are all on the deflection board. You can get replacement deflection boards for the RCA ITC222A TV( which is what your model is) from www.tvrepairworld.com they also include instructions how to remove the old board.
