check all the usb ports and hdmi for any damage, any pins touching eachother especially in the usb ports can cause a short resulting in the console behaving like its dead

edited just noticed you already checked

might be an idea to take the board out and post some good quality close pics of the motherboard
Hi i have one opened but i don't see any blown caps ! or could be the port where you put the ps is fried or maybe something else ! Usb and hdmi im 100% sure on them because this is the 3rd xbox not showing sign of power with this faulty power supply !

well considering the value of what xbox 360 slims are now worth a lot of people would say it's not worth the work that would need going into it to repair it as it could be so many different problems bad cap, yes i know you say you checked, also bad mosfet(s) plus many other items supplying current on the board, however the problem at hand as you mentioned in your post is his power supply has killed 2 consoles and a red dot motherboard of yours that you tested. bottom line is its not worth throwing money at them perhaps to learn on yes.

yes you could replace mosfets and see how it goes but remember that you cannot test mosfets while they are on the board you have to remove them to test unless you have specific equipment designed to check them on the board. good luck with them hope you manage to sort them and perhaps more members may come along and help further.
