VA1 GG does not turn on after two recaps

Hi!!

I completely replaced all the capacitors on my VA1 GG and it worked for about 1 hour, then it turned off and never turned on again, the red light stays off and the display lights up for 1 second when turned on, then that's it.  Then, I replaced again all the capacitors but I have not solved anything, it continues to have the same behavior. If I try to power on only the power board (disconnected from the main board), I measured correctly both 5v and 34v on the cn1 connector, but when I connect it to the main board I have no more power on the main board.  I have checked and I have not found any short circuit to ground or something like this. Do you have any suggestions? Are there other components to replace?

many thanks!!!
