panasonic plasma tx-p50xt50b and chip U203

[r40pmd]

Hi all im very confused about the chip im going to replace on 50" plasma tx-p50xt50b on PSU, its marked u203. I have the skimatic which matches my board, but when i went to ebay to buy the chip it does not seem to match the pins and what they do, i have uploaded pics so you can see my problem the pin that says N/C and the dot on the chip are in the same place but the pins and what they do are not. My board i have matches the skimatic i have, but the one on ebay allthough has my model number in picture shows pins doing wrong thing in wrong place, i can see how common this fault is by ammount sold has any one come across this problem that can point me in the direction of a match for my tv thanks all

Well in schematic the pin order is not representing real IC pin order, you can notice that one side is going 8 1 7 2 and if you check datasheet of IC you will see that connection is matching the IC pinout, so pin 1 in reality and schematic is Vin and so on.
Therefore get that IC (FAN6755U), put it in and don't worry

The pins on the schematic are not in order for ease of drawing and layout. Compare the numbers beside the pins on the schematic to you other picture they should match.
