changed these capacitors and the TV had powered up already but the pic is not normal with 3d appearance with shadow green backround,tried to adjust the hstat and screen control ,the 3 orange lit in the crt is normal.check open resistors/dried joints near jungle IC 301 including board at the back of the tube but nothing happen. pls help.

Note: this is not the same sony TV that i have posted before in this forum,thanks a lot for those people who help me ,my other tV is working great until now.

If degaussing it cured it temporarily, I'd suspect the thermistor.
