Need a Power Supply / Deflection Board for a RCA D52W20BYX1 TV
I am looking for a power supply / deflection board for a RCA D52W20BYX1 TV. I ordered an RCA 258762R from PartStore.com but it was not the exact same part. It was close, but I had no connections for BP011, BL501B and the BL500 connection had a notch in the wrong place.
I return the part and PartStore.com suggested RCA 264102R. I looked it up online and it looks nothing like the part I need.

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~~~~~~
Yes ,this set has built in tuner,located on the SSB board next to the Deflection board.
Bottom 2 chassis onthe right is the deflection and on the left is the ssb board and right behind ssb board is the AC power supply board.
You can ship these boards for repair if you are unable to Fix it yourself.

Replace the deflection/power supply board and return the convergence board. There are probably bad soldering connection points all over the bottom of that board with the fly back transformer. Slight soldering skill required.
This televison had problems with electrolytic filter capacitors in the secondary of its switched mode regulated power supply. Look on the power supply/deflection board and replace all capacitors with domed tops. These are usually in the 2200 microfarad range.
This is a convergence power supply problem on your deflection board. There are 2 small bias fuses on the deflection board that has blown, usually this is caused by bad connections on the flyback transformer, it is also possible that the convergence power supply has failed also, but normally on this model open micro fuses on the deflection board is your prolem.
Please leave comment if more info is needed.
ALL of you have a problem in power supply/deflection board 3 capacitors open located cp150 2200uf 16volt and two 220uf 35 volt, check them first then resolder around FBT other wise order new deflection board 125.00
