I've finally receive my flyback , been changed.

Now tv powers on/off by itself , randomly.

I get a quite nice pic ( I cannot have time to tweak it , it shuts off) , and menu doesn't seems to freeze as before .

What am I missing ?

Solder been checked everywhere , tacts switches checked (and disconnected too), same thing.

Any feedback welcome.

You already replaced
the flyback, so maybe you should try replacing the front panel, which is
a circuit (part # 263376). It is NLA at a lot of sites,

Check diode DP036. May be leaky.
Also If it has the stand up board the (EWM) next to the flyback replacing it sometimes fixes that
problem. I had one on a Model 36V430T

This one is for a 35V432T that cycles on and off.
Check MAV board (Master Audio Video board) if it has one on that Model p/n 263404. Remove it, If set stays on that's your problem. Might aslo check the 12 volts reg. TX508 for leakage between E-B, part# 257827 (2SA1013) in the MAV board.
That's all I have. Hope it helps.

RCA ITC008 32V550T Shutdown Unit shuts down right after turn on. Unit
has vertical and horizontal sweep.
The tech opened DL062, board coordinates for this is U11. Located just
left of the flyback as viewed from the back of the set.. This diode
monitors the pincushion output transistor. It will shut down the horizontal
drive at TL061. problem was a defect in the pincushion circuit. Recommend
replacing pincushion board Part # 263370.
