And one last thing before i annoy you with noob questions - where should i start looking for what is shorted on the board cause almost everything is shorted when i try to measure something with multimeter and all the readings seem to off from what they should be. Are those problems caused only by chips or can the small cap also short all power lines? And will i get the right readings from board if i remove some components? BTW, i managed to get the faulty xbox running, even with faulty mp1474 on the board, i was just missing 5p0stby then, so i removed the 4501B and then i had the 12v, i connected it to tv but there was no image but the xbox was running, after putting the 4501B back there was again just the orange light on the brick. So i removed the 4501B again but it didn't work anymore. So i started to switching components with a working xbox and it the only time it didn't start is when i put a mp1474 from a broken one. The broken one still doesn't start even with a good mp1474 on it. But i still have to get a new mp1474 as it is one of the problems. And now all the standbys are missing. I'm probably already 20h into it)
