Ps4 Glitching Image

My Ps4 glitches when i start it. When in safe-mode, it doesnt. Any Clues why this is like it is?
I took i apart and the only obvious was that the power supply sounded strange and felt strang in my hand. i cannot descibed it better sorry.

the glitches are that bad, that i can see only for a second sometimes a bit from the real ps screen.
it looks like when an old tv got no signal and rustles.
i hope you understand what i mean. any clues? the hdmi port looks normal.
