HD52W67 RCA YR.2005 The picture is concaved the color is shifted slightly to one side. When I went to menu convergence it shut tv off then came back on without the convergence menu there. I was told to check the IC's attached to the heat sink (STKxxx) I do not know where to look or what they look like or what they are,im veary mechanicly inclined and would enjoy the attempt to repair this. Any info would be appreceiated. Thank you, Adam

Look on the board next to the flyback you will see three small brown plastic rectangles. Those are fuses the center one is FL231 that fuse and possibly diode D231 and capacitor C231 is blown thats why the convergence option is no longer on the menu. If you need more info please respond to this sme post so I have access to the info again.

    here is a picture of the flyback if you look next to it on the right you will see three small tan rectangles. The center one is FL231 and then you will need the convergence power supply board for the ITC222 chassis. I know they have a promotional sale on the convergence boards at the following link where you can get the power supply board at a really good price, they have the fuse as well. Heres the link.

My RCS HD52W67 is showing three pictures on the screen. I have tried zooming, but it only makes all three pictures larger. I cannot get it to only show one screen. What can I do?


Your TV most likely has a convergence failure. You can get parts and instructions from www.tvrepairkits.com Here are some of the most common symptoms and example photos of a convergence problem Screen looks 3D Colors don't line up One or more colors can't be adjusted when using the convergence menu. Screen is bowed or warped.

Here's all I find regarding bad convergence from the techrepairCD:
RCA ~ITC222 D52W20~Convergence bad~~~ITC222~Replace leaky DL032 on
deflection board~~~~~~

RCA~D52W20Y ATC221~Convergence goes out/bowed after on for a few
minutes~~~ATC221~Problem may be on the deflection board. Was unable to
pinpoint where in this case.~~~~~~

RCA~D52W20BYX1 ITC222~Convergence way off after replacing small signal
board~EEPROMS were transferred over to new board~~~IK210 was
defective..transfer the new EEPROM back over.~Remember on these
sets*when replacing the SSB* if there is a small P on corner of
screen*hold volume on remote for 8 seconds after it reaches minimum.~~~~~

RCA~D52W20BYX1 ITC222~Can not align blue convergence* bottom really
bowed* possibly either color after replacing SSB.(Or no auto
convergence.~(Service menu: turn power off for 30 seconds* press vol dn
and ch dn* simultaneously for 8 seconds* set turns on with service menu
options)~~ITC222~In service menu* select convergence. If sensor
calibration was performed when convergence was too far off* it will not
alighn.~Get crosshatch with straight lines* perform sensor calibration*
then attempt convergence alignment again. Be sure to store settings*
then do sensor calibration again.~You must get a green flash of the
screen after sensor cal and a check in the box. RED flash indicated
convergence settings are too far off~~~~

RCA~D52W20BYX1 ITC222~no convergence correction~~~ITC222~LP650
(259271) DP670 (259246) & RP632 (259564) 4.7 3W on convergence power
supply board~~~~~~

By admpeek on Jun 25, 2008 When I turn it on the picture is concaved, the color is shifted slightly to one side, and there are 3 skinny lines across the top. I went to convergence menu and clicked it...


You have a blown fuse on the Deflection board FL231 it will be on the righthand side of the flyback Transfomer there are 3 of them in a row they will look like small brown retrangler caps, it will be the one in the middle. I had this problem myself just several months ago, replacing this fuse fixed the problem. That fuse controls the convergance of the 3 CRT's, without it the tv can't converge so you don't get the option in the menu.

I have a Mitsubishi 55 inch rear projection tv, ws55819 on which the convergance is gone bad. I'm getting a concave picture with multiple colors and black lines with a blurred picture. this happens mutiple...


Your reference to concave picture suggests a high voltage problem and not convergence. If the raster can't scan from left to right , top to bottom, your having High voltage trouble. if your colors are not dropping on top of each other that is convergence. I would suggest it may be time to consider a purchase of the new HD set for the cost of this repair. good luck

This is what is known as convergence. a projection tube ussally has three picture tubes.. red green blue. they all have to align. the concave picture indicates complete loss of convergence or convegence power supply. First question on these sets Do you have the convergence option in the customer menu under setup. if you do not this is a indication of the common "FL231 fuse problem" and inexpensive simple repair. I have wrote and artilcle on this under my tips and trick section. If you do have the option then next does autoconvergence work. in you case i would not think it work. under blue and red manual convergence does the crosshairs move. if not then this is indication of convergence power supply board. if they move at all this may indicate a convergence amplifer problem.

My HD52W67 has concaved picture


This is a convergence problem and can be repaired relatively easily. If you can solder, you can fix this yourself. First try resoldering the pins on the convergence ICs. If that fails to resolve the problem, replace the ICs. These are large black ICs attached to a heat sink and should be marked STKxxx.

Keep us posted.

My RCA Tv has a concave picture!!!


Convergence problems. FIrst try going into customer setup and seeing if convergence options are there and if adjustments can be made. unfortunately when the picture is bowed like that it idicates a complete loss of convergence which idicates one of three boards have gone bad.
