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~~~~~~

Convergence problem???

yeppers..those chips are soldered(more like welded) into the board, and usually runs you around 300 to 400 buckos..

Pt5598 rplaced convergence board no luck.

If the picture is still bowed, the power supply fuses are open.
Check the power supply on the red connector for + and - 20 volts.

The fuses are on the main board,are on the deflection module in the middle, tward the front of the TV. They should look like green (or brown) resistors. An ohmmeter check will show which ones are bad.
They should be 3.5 amps. Replace with 4 ohm GMA fuses with pigtails if you can't find picofuses. I also had a set that would fry the 1 ohm resistor on the 20 v supply. This was near the fuses.
I replaced the whole module to fix that.

I hope this helps. Lee,

Distorted Screen for RCA HD56w66

convergence is the problem. first question do you have convergence in the customer setup menu. if you do not it could be a special small fuse if you do have "convergence" in the setup menu then you most likely have a convergence power board issue. and generally they are replaced. in our shop such board replacement average 124 labor and about 100 for part. if the fuse bout 15 for part and 80 for labor. there are solder connection that cause the blown fuse

Sony KP-46WT510 Rear Video Projector Convergence Problem


Video bowed in, convergence out, PS5001

Symptoms / Customer Description
Video bowed in and convergence is out.
[Primary Symptom Code: 1436 ]


Found PS5001 on G board was open.

HQ Comments: Could be cold solder joint on one of the STK IC's on the D Board. They run hot and the solder connection might have broken down causing intermittent condition which could have opened the fuse on the
-22v line.
