Samsung
TXJ2566
codeing is X/XXA
Chassis has marking of K51A but also has sticker on one cap of THE2566

       The only reason I make note of the chassis is that the Schematics I
have seen floating around are sliglightly diffrent: the SW Ic is the same
but the diode that I have on the seconadary is numbered diffrently. The Set
has IC 801 (makred 3S1265R with the logo SEC) is KA321265R that appears to
be now made by fairchild after they took over the samsung semiconductor
divison(it also appears fairchild is recomending another part for new
designs although pin for pin they look the same). The Diode on that shorted
the entire B+ is D811 which is makred RU20A (the Schematics that I've seen
show D812 in the same location as FMG-G28S). I have not found any other
damaged componets other than a blow main fuse (the main regulatior had
cracked and blown its guts out on the board). the customer as always wasn't
too usefull -it quit a year ago... I checked for further B+ shorts and found
none. Any Senerios common to these or should I suspect a power surge.
