How badly is it bowed on both sides? if it is too much. ther is a fuse resistor that is gone bad near the coil in the east west section. you need to replace that. if it is not too much..you need to get into the service mode to fix that..good luck

OUR SONY PROJECTION TV IS DISTORTING THE PICTURE BY BOWING IT IN AND ITS SHOWING RED AND GREEN COLOR DISTORTION. HOW CAN I FIX IT?

You will need to replace the sub deflection board or convergence I.Cs and check around the circuit for any o/c capacitors or resisters

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~~~~~~

Picture on rear projection t v is bowed in at the sides and picture is blurry. color is ok.

Go to menu then setup see if you see convergence ,if you do not then you have a blowed fuse FL231 it will be on your deflection board over on the right side of your FBT flyback Transfomer there is 3 in a roll small brown rectrangler looking caps but they are fuses it will be the one in the middle.

Samsung tv model # HCP4363WX Ghosting

The convergence board that you replaced will not correct the issue that your describing as your model has the convergence amp circuits located on the Deflection board. You would need the deflection board which is available at the following link. It also has a picture of the board which is in your model its the large board on the right with the Flyback and both Convergence ICs on it.

Bowed/Warped picture/convergence problem

There is 2/3 boards on bottom first board to left is the Deflection board next to it is the SSB board it has the tuners and video jacks on it. Deflection Board has 3 fuses right in a roll on right side of FBT Flyback Transfomer (FL231) it will be middle fuse 400ma they do not look like fuses they are small brown rectigular you can pull top off of them with needle nose plyers to check fuses on top.

Picture out of convergence

cost of repair about 350.00 if you find a good shop

Picture is suddenly "bowed" and the convergence is askewed at everypoint but center.

the problem is the EW cicuit of the deflection cicuit. this is a component level repair call a tech. the EW or East West correction is apart of the horizontal deflection. IC431 is the pin amp.

The issue is the Deflection board. The Fl1231 is open. The Deflection board needs replaced

Horizontal hour glass picture

The convergence Ics need replaced. In Hitachi, resistors and sometimes a coil needs replaced as well. The convergence/deflection PCB is available, but, the cost of that board is higher than having a servicer come to your home and repair the unit to component level. If you are not familar with this circuit, then call a servicer. Have them replace both ICs not just one. Make sure they are repairing to component level and not replacing the board. Hope this helps.
