    Fixed.I found bad solder joints in the primary circuit of the convergence power board.

Picture for our RCA 52"


nakithajamer,

You have a convergence problem. The convergence ICs are basically amplifiers which take the information from the digital convergence box and make corrections to the specific color beams. They are run hard and over time and with heat dry out the heat sink compound and eventually overheat meaning you have no convergence correction. The solution is to replace the ICs. I have a tip at http://www.fixya.com/support/r4220499-change_projection_tv_convergence_ics which explains the process as well as tells you where to get the parts. There is also a link if your unit is a newer one which has the ITC222 chassis. You did not mention the model number.

Thanks for using FixYa and for the great rating.

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~~~~~~

Rca d52w17 convergence off on 1080i signal only tv works fine with 480p signal.


you will need to adjust the geometry and convergence defaults for both the 1080 and 480 seperately then save. You can get the CD called the ITC222 chassis convergence and alignment CD which shows how to do that from www.tvrepairworld.com

I have a 52" rca hdtv. the screen looks like its in 3d. can this be fixed? model# hd52w67


It seem like a convergence trouble. I tink it is a ITC222 chassis in this set. If it is, you probleme is eeprom for convergence need to be reprogrammed and cause no power on convergence board.

Who does in home TV repair have an RCA D61W20 or can it be done m


The most obvious item which is causing your problem are the 220K ohm 1/4 watt resistors on the convergence power supply board. There are four of them RP10, RP11, RP12 amd RP13

RCA R52WH74 (ITC222A Chassis)


no the board that has the FL231 on is the ITC222 deflection board. The other board is above the chassis in a seperate frame that runs across the set the convergence power supply is the board on the left above the board where the fL231 is. Yes the ITC222 and ITC222A are the same chassis. As for the service manual that site should have the service manual under the thomson category as the ITC 222 chassis is actually a thomson chassis made for RCA.

RCA R52WM24 52 in. HDTV convergence IC location


the rca itc222 chasis uses no stk the convergence is controled with transistors... the convergence amp board is located above the main signal board(green board)... it can be identified as the one with several heat sink fins on it. FL231 is related to convergence.. there has been a problem with this fuse when it blows the processor doesnt know it is a projection set so it turns it into a regular tube tv. Here at the shop we have found number one reason this fuse blows is poor solder connection on the flyback. So replace the fuse and reflow the solder connection on the flyback and around that area also the horizontal transistor and then see if that doesnt fix the problem.. if you have an more trouble ..... willie@fordtv.com
