If you know how to use a multimeter, I can show you the voltage test points.

Have a Q for you here about SSD, if you ever had this problem
Phoenix Pro SSD (SandForce), working means detecting and reading OK
but Unable to FORMAT it or RE-USE IT
kind of Stuck somewhere (which i dono where really) but looks Intresting really
when its DETECTING but unable to:
1- Format it
2- Copy Anything TO IT - but can TAKE FROM IT
looks very Strange
if this damn SSD was a HDD, i would think of many reasons, but as an SSD, nothing
btw, i tried many formatting tools such as:
1- HDDScan
2- Guru - LLF
3- Windows format
all of those shows formatting progress, i leave it for a while then i stop it
then when i disconnect n reconnect it back, Damn it, everything comes back like NO ONE DID ANYTHING TO IT
i was laughing today about it, but really never had similar case like this, and i assume you too
let me know my dear

The location for F1 (yes, it is a fuse) has been left vacant because the design allows for R1 or F1 but not both. The only reason I asked you to measure the voltage at that point was that it is more accessible than R1.
Coils L1 and L2, plus their associated "OFA" ICs, constitute two switchmode regulators. The voltages at the coils will be the outputs of the regulators.
TPS62065, Texas Instruments, marking OFA, 3-MHz 2A step down converter:

I can't make out the markings on the IC at U7, but it appears to be a POWR607. Its function is to monitor and sequence the onboard power supplies and to provide a watchdog timer to reset the controller in the event that the firmware gets stuck in a loop or the controller hangs.

I'm a bit concerned about the "stuff" in the top right corner of the IC. It could be a manufacturing mark (the IC is in-circuit programmable), but I'm not sure.
The IC monitors 6 voltages (at pins 1,2,4,5,6,7), but the circuit is suggesting that there are actually 4 voltages being monitored. I would measure the voltages identified in the attachment.
I can't make out the markings on U22, but the logo looks like it belongs to Fairchild, so it appears to be a power IC of some kind. Could you tell me its markings?

correct: The actual voltage monitor pins (VMON) are 2,3,5,6,7 and 10.

about other voltages
Fuse pins to ground = 4,9V
