I have an rca r52wh77 it is bowed in the top and bottom. it also is way off in convergence and i can not seem to get the crosshatches to come together. i have changed the fl123 part that was sent in my kit but it did not work at all and noone is writing me back from that company to give me advice. can anyone help.

    i have not seen a convergence chip for this model tv starting with stk###. i have been through these televisions before and has not seen one suc as that

    i replaced the fl123. it looks like a capacitor and it sits beside the flyback. i resoldered the flyback but i am still having the same problems. what could this be.

  • Vernon Johnson
    Vernon Johnson May 30, 2011

    no it did not it only came with that small chip. i have looked and i do not see a convergence chip for this type of tv. i do not think it carry one.i have changed chips before and the included resistors, but in this tv i haven't seen any of these.

    what i have done is replace the fl231 fuse beside the flyback. i have also resoldered the pins on the flyback. i have taken a similar tv apart all the way down. i still have not seren the large convergence chips that would maintain convergence and i did not see them. i do see some finlike heatsinks that has several amps cdonnected to them. it has the connections from the crt's.

    it seems as if there is a magnetic interference when i go to a snow screen. i can see the magnetic flux lines in the snow. why is this

    i have checked the diode and the cap and those are not the problems.

    i do not have it close to anything magnetic. i will try to get a degaussing gun, goodnight for now until thursday.

Does the kit have a pair of convergence ICs? That is what you will need to fix the convergence problem. The kit should also contain thermal grease(a white paste that should be applie to the ICs before you solder them) and resistors that may also need to be replaced. When a convergence IC blows its usually due to failed resistors.

    Ofcourse it has a convergence IC. This is a CRT rear prjection tv which contains 3 CRT tubes at the back of the set and the convergence ICs are mandatory to converge the 3 different colored images produced by the CRT. You can remove the back cover and see if you doubt my word

  • eagle338
    eagle338 May 30, 2011

    May be you are right. Some of the older RCA sets use 2-3 transistors instead of ICs. If the set is about 10-15 years old then that may well be the case. If thats the case please get me the chassis number of the tv and I will try to find a service manual

  • eagle338
    eagle338 May 30, 2011

    Well I do have service manual but only for the power and video amp board. I will look online and see if I can find a more comprehensive service manual

  • eagle338
    eagle338 May 30, 2011

    Ok. It seems like I could locate some service documentation. Are you able to see the convergence option atleast? If not then along with the fuse you should replace the capacitor and the dioded included in this kit. Is this what you have purchased?

    If thats not what you got then you can either give that a shot or replace the entire convergence board.

  • eagle338
    eagle338 Jun 01, 2011

    If you are sure that they are magnetic fluc lines then it has to be degaussed with a device known as degaussing gun. As for the cause not sure they appear when the tv is close to a strong magnetic field

Good day!


That TV is have a convergence IC (STK####)

If your problem is convergence please replaced the convergence IC.

Thank you

    • Good day.



    • Yes,the problem is the convergence.

    • I give you the information on how to fix that.



    1. Remove the cover of your projection TV,by loosening all screw.

    2. After that,you have an access to the projection board.

    3. Try to look at the CRT projection driver..

    4. Pull-out the CRT projection driver from the unit,to repair it easily.

    5. Look at the convergence i.c. .STK392-570 and check some resistors and diode near that.Also look for the leak/bulging top capacitor..

    6. If you done step # 5,and If you found some chance value
      of resistors,shorted diode,or leak/bulge capacitor.Replace it with the
      same type and ratings.

    7. Also replace the convergence I.C.And I already check the supply at eBay.com.They have stock,that convergence i.c.Buy now!

    8. Use Soldering Iron and Soldering Pump to replace the
      parts.Be careful for replacing the parts,please double check always
      specially when you replace the capacitor,it have a polarity(+/-).

    9. Finally,when you already done this procedure,test it by power ON the unit.
    I hope this solution will be helpful.Please don't forget to rate my answer. thank you

    OK good luck just keep on touch

  • bonifacio gomez
    bonifacio gomez May 27, 2011

    NOTE: the part # of the convergence I.C that indicate above is not the actual value.
    But the value is start with STK####?
    thank you

  • bonifacio gomez
    bonifacio gomez May 30, 2011

    what is part # of the big ic that found on your TV.

    try to enter the part # of that chip here:http://www.alldatasheet.com/

    after that the specification of that ic is appear.look if is convergence ic and try to replaced it

Screen lookes like colores separating


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~~~~~~

On our rca hdtv model # R52WH77.. the tv is having like a 3d look on it and has a bow in the picture.. we bought the convergance repair kit from tvrepairworld.com and replaced the 2 parts it gives us.. ...


have you reset the convergence parameters after installing the kit to fix the option? Usually you will need to reset the defaults to get the outer edges back in alignment.

It seems the picture has gone bad on our our RCA 52" Model No. R52WH73 projection television. It is only 3 years old. The picture is bowed in at the top and bottom and the color is off. Will it be cost...


Your convergence ICs or convergence board is bad. More than likely it is the convergence ICs. About a $100 fix from a reputable repair shop. Hope this helps. If you need more info let me know.

ALright. you might have a simple inexpesive problem...MIght... first question If you go into setup menu do you have convergence option.. if you dont this it is a small special fuse that blows because of bad connections... can you solder electronic components. the parts about 5 bucks and takes less than 30 min to replace. Let me know if this is the case.

RCA R52WH77 convergence missing from menu


THis is very common on these sets. there is a special fuse thats cause this.. kinda hard to get rca part number 259213.. .4 amp. the reason this blows is there is bad solder connections on the flyback. so when you replace this fuse you have to resolder these connections. so if you know how to solder and can find this special fuse. it is a fast and easy repair
