Chosen Solution
I disassembled my ps4 slim to remplace thermal paste and to clean the disc drive but I forgot to take out a disc from the disc drive so I removed the metal plate from the disc and the cd and I cleaned the lens and opened the door manually using the plastic screw but when I powered it on it won’t take the drive the wheels won’t even spin it just does nothing And i noticed something when I powered it on a black game square with a disc symbol in it appeared for a moment and went away
If you have a total lack of power, check to make sure that you plugged all the ribbons back in correctly. If so, then chances are you’re looking at a blown fuse.
