Check all fuses. If you have power going into the power supply board..but none coming out of it...I think you have found your problem. Get a new power supply board.

I have encountered this before---there are set top boxes that will convert the NTSC to PAL and the only other concern is the line voltage being the same or not.

You know how to reset the tv to its factory setting, I think you are a technician. Second thing you can do is software update. Go to http://esupport.sony.com/US/perl/swu-list.pl?mdl=KDL42V4100&LOC=3#div_pos_30 . If it doesn’t work. Replace the Main board (UB board). Part # A-1547-086-A Cost approx $320.

Knowledge obtain from: Repair experience on same symptom.
