I'm trying to fix a panasonic plasma,P50S10B model,its SU was shorted,and caused SC board to fail,IC791,the orange one in the picture(i had a lot of trouble to desolder it with a 40W soldering iron that's why it looks like that) was shorted,couldn't buy it separatedly,I mistakenly bought a board for P42S10B,the 42 inch model,i have that TV also,tested the board and it works,then i inspected each board side to side.
The only difference is 2 resistors which I corrected and this IC791,it's black instead of orange,but the service manual list nothing about this part,can't any find info on it,I want to improvise or modify it so i can use on this TV,when the TV is powered on,panel does nothing and 7 blinks,before i removed IC791 from the original board the screen would go white and rainbow colored.
PN is the same for both boards,TNPA4829.
