No solder V4 problem
 

I just put in the no solder on the PS2
I hold the eject button and the power turns orange and ejects fast as normal.
The problem is the tray won't automatically go back in and the light turns green.
Anyone!!!???!??

I double checked all my connections.

Make sure the mod is completely pushed in. It's most likely a bad connection. Most of the time if it is a bad mod the tray wont open at all.
