    Are these chips on the replaceable
    Samsung AA95-00705A Deflection Board. If so can I just unplug this board and plug the new one in?

The convergence chips in your tv have gone out. They control the three picture tubes and align them so that they create one picture on your screen. I recomend having a qualified technican replace them and realign you convergence. Thanks.

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~~~~~~

I've been having this problem for a while. when I'd turn the tv on I was able to watch it for about 15 minutes. suddenly the picture and voice would turn off, but the green power button was still solid...


Sounds like it may be a power supply issue. I don't know what "modules" the tech replaced, but I would have advised you to scrap the TV for a newer model as they can get pretty expensive to find and replace parts of the older rear projections. Sorry I can't be more help to you.

Picture is concaved and all the colors are off.


you will need to get a convergence done and the resistors on the conversion IC's checked and bad ones replaced

maybe on your remote press menu and find converence and use the keys to move the red first over the green then move the blue over the yellow ..by standing back and just using the remote....should end up with white lines. and dont hit that button again once set. a tech should do this quickly and charge you minium.

61 inch proj. warped concave picture.


Josh Any chance you could send a photo... Too many ideas come to mind from what you've described. Would actually have to see the "warp" in the picture itself to see if it's one or all colors, any boarders and if the bend is actually pulling from top or bottom.. Bill premtech@willapabay.org
