[SOLVED]820 3536 no data from SSD or USB

[Ryanlen2]

This came in with liquid and corrosion around C7090-C7092 and F7005... Very quick easy power issue. Board powers and chimes but only shows flashing folder. I have tried booting to USB. It will power USB but not read it. With OPTION held down with USB and SSD I get only the network option, no available drives. Is this thing EFI locked you think? Doesnt show pad lock on screen...


Update - Not EFI locked and SSD works in another machine. 3.3V at L3700. CPU?...

Both USB not working?

Both USB not working. They power on but nothing recognised.

Sounds like a clock issue, but then it would also not see any networks so confirm that. If it does not see networks check 24MHz on Y1915 and check traces.

No networks... Checked around area you suggested and noticed that L1295 didnt look great so I changed it and things are now working.
Thanks Duke... Appreciate it.
