Hello guys!
Im faced with an issue with WD140PURZ. Looks like my friend miss SATA power module output in power supply and put SATA to PCIE. Now hard drive didnt shjow any activity like no power. I think is it possible some TVS diode died? Here is board photo, please help me to understand do i need tu loking for board or i can replace TVS? It yes where TVS on a board and models of it?)

Diodes are top right near the power connector - also check the tiny fuses/resistors just above them.

Checked all of them. All without beep and ~200 on a multimeter:(

Not sure what you're measuring there - the fuses should have very low resistance and continuity and the diodes should have continuity and low resistance in one direction. fzabkar has a guide about protection over on hddoracle http://www.hddoracle.com/viewtopic.php?f=100&t=1615

I have already pointed out an open fuse at Tom's Hardware, but the OP hasn't replied.
