Hi,

You may not be able to realign that picture without some new parts unfortunately. The magic focus will not be able to correct it, as it is a hardware failure. read on...

There are some circuits that align the RED, GREEN, and, BLUE, picture tubes to make the picture you see.

**Please understand that by opening a TV you are exposing youself to many dangers, including electrocution. Be sure that the set is un-plugged and keep one hand behind your back whenever possible to avoid a shock through the heart as this CAN KILL YOU. If you have zero electronic experience I would not attemp this repair.**
OK, public service announcement over.

The components that do that job are called "convergence" circuitry. The usual components to fail are the "Convergence Amplifiers" which are usuall a pair of Integrated Circuits mounted to a large heatsink. (STK-392) may be printed on the IC along with some number such as 110, 160, 120.


Also look for burnt resistors around these components, as it is common.If the problem is isolated to only one color the replacing those STK amps and any burnt resistors will fix it. If all the colors are out of whack (Red, green, and blue, like a 3d effect all over) then you are likely looking at a fuse gone bad in the voltage supply to those amplifiers. Usually Sony or Mitsubishi have these fuses. The fuses (called "pico-fuses") are generally orange, or green, with no color stripes like resistors have.


You can look up these parts online easily with the exception of the burnt resistors and fuses which you usually need a manual(which you can also purchase online). The STK's price will vary from $15-$90 depending on which one, and the resistors have to be of the metal oxide type so as not to change value with heat.

One place to get parts is www.partstore.com


If you want a professional to repair it, be prepared to part with around $300-$400.



Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Need to align colors in convence option can move them just dont know where to


Convergence adjustments are made by aligning the Blue and Red to the Green... Make sense? Green does not move, it is the fixed point by which the other 2 colors are to be aligned to.

Picture is OK, but colors are off and there is a blue star background that shows on dark colors.


Hello, With most rear projections there is usually an alignment to do with the set up with your TV. This is so the red, blue and green projectors align together to give the correct colouring. This sounds to me what may be causing the outlining of the blue. This can also make it seem off colour. Look in the set up menu of the tv and see if you can find this alignment feature. Usually a cross will appear and you move a blue, red, and green cross with the arrows on your remote to align over the original white one. If this does not work, it may also mean that one of your projectors, that is the red, blue or green one may be failing causing the off colouring. Hopefully this alignment may fix it for you.

RCA 52 in HDTV red, green and blue colors not alligned - concave


That repair only repairs the issue of the convergence option missing from the on screen menu. If thats what your problem is then the ITC222A convergence option missing repair kit at the following link should repair the issue. The kit contains the fl231, DL231, CL230 and the CD with detailed instructions.

The colors are distorted and it seems like the only colors that really show are blue, green, and red. When you turn the TV on you can see blue, green, and red lines across the screen. The picture also...


Hi there, this is what we call in the industry convergence board failure. this board regulate the rgb and keeps everything in order so the picture looks nice and clean. when this board starts to malfunction, what you are witnessing is usually the result. I suggest repairing this convergence board. this will fix the 3-d effect.

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~~~~~~

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.
