Installed an X3CE in a ver 1.0 and had trouble with DO lifting off and had to do trace repair. Then used alternate DO location on front of board. Xbox boots ok into 3.01 and flashed it via http to X3_1959 but get a blank screen. I have resoldered all pins in header twice and still blank screen. I have even removed the header and gone the wire solder route with the same problem. All lights on the X3 and front panel light as they should. I have read almost every thread I can find on this topic and most lead to a bad solder but I am quite certain that s not the problem. Could it be tht the do wire is the problem?
