Hi My xbox 360 corona (4gb model) was not turning on at all, so I replaced u5a1 with the ams117-3.3v and now the console turns on but just beeps, no light on the RF board, Power supply LED is always orange. The console was working and booting on retail fine but now it is not I have tried different RF cards and checked voltage, The board needed some work doing to it as a trace repair and some of the nand pads had gone so needed alternative points, also the trace rebuilds were around the U1D1 area. According to the forums others have had to repair traces or replaces smd caps or resistors to get it working I have checked all my joints and traces, with a multi-meter but the console just beeps and is not turning on Firstly I just want the console to boot on retail/stock I dont have firmware backup Please people help Thanks so much
Blinking without starting - it's power, nand hardware or nand image problem. You can re-solder with flux small smd near south and 4Gb SD.
Can you provide tutorial Pls But i don't think it's to do with that. Can you provide voltage for u1d1 please
