Try resoldering both convergence ICs located on the D board if that doesnt correct the problem you will need to replace both ICs let me know if I can assist you further.

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~~~~~~

Just a thought, but check all of the pico fuses for a blown fuse. The pico fuses look like a small yellow resistor. Some Hitachi's are famous for having a blown hi-volt ceramic capacitor and a blown pico fuse.
I think the red led on is a short protect indicator, but I could be mistaken.

Intermittently screen move to one side with distrited picture


Might be the convergence chips. Do you have any problem moving the convergence under the menu setting? Convergence chips are reasonably priced. If you know a friend or someone who can solder better than average, I would go this route. My tv wasn't that bad; I wasn't able to set 2 of the 3 colors during convergence setup. Changing the 2 convergence chips did the trick!

Possiblility include bad convergence cuircit. A component that is overheating and bad solder connections.. Technicians can use special equipment to read error codes... this will tell them the error that is shutting it down

Unplug the three red-blue-green plugs nest to the convergence amps. If the unit powers up and stays on the picture will look bad but will confirm that the convergence amps have failed...
Replacing the amps and one or more resistors in the yoke return will restore the set to normal operation..
Use only Sanyo original Ics..
