Did you check the 24 volt output at the power supply? If the power supply isnt putting out 24 volts, I'd be looking for a fuse, it might not look 'fuse' like, but will probably be marked F1 or F2 etc on the board. Next up, check the diode on the 24 volt rail on the psu see if its shorted or open. Cant think of anything else atm, but if ya dont get it going in the next coupla days, Ill bring over some special goodies to test it with.
I have some spare inverters as well.
Special goodies are good
The fuse at the 240v in is good.
The second fuse in the center of the board is good. TV wont start without it.
All cables have been unplugged and replugged to make sure connections are jiggy.
I'm out of the shed now (bloody mozzies) otherwise I'd pull the power board back off and have another look at the solder joints on the boards under side.
Samsung LCD backlight fix.
I had it off today and noticed similar shaped solder joints like the one shown in the above video. (I hadn't seen this video then)
I'll do an update tomorrow. Cheers
