S1= 4.97v, G1=11.94v, S2=12.09V, G2= 28.6mV, both D1 = 4.97 V and both D2 = 12.09VĬould it be that the MOSFETT is faulty coz I was able to get connection once when I pressing on that part of the board? The readings at the MOSFETT are as below: I did not see any fried components when I took out the board, reading at FB12 was consistent at 12V so power input is okay. I've tried different USB cable and power supply but the problem is still the same. Also the board would not powered off (with the power button) unless if I disconnect the USB cable from the PC.

The board can only be powered up when the USB cable is not connected to the PC (with the power button) and nothing happen if I connect the USB cable to the PC after that. It has this high pitched buzzing sound when the power supply is connected to the board and it would not power up (LED light on) if the USB cable is connected to the PC. I'm having a weird problem with exactly the same type and board model which i suspect maybe caused by voltage surge. I can't seem to get clear pics, but nothing seems discolored, just the usual oxidation which I have cleaned up with an eraser. Should I try another bridge board from an exact enclosure? I tried to PM fzakbar but I wasn't allowed to. The drive itself is a WD30EZRS-00J99B0, WWN:50014EE2B04A7AAB So I removed D4 nice and clean, no luck yet. (when touching leads together I get the same reading from resistance of my MM) My pcb, 2061-771698-802 AA, it looked fine upon visible inspection but I tested the R64/D4 12v and R67/D3 5v with my multimeter on the 200 ohm setting. My bridge board, 4060-705089-001 rev.p1 (back side print) same on front sticker except it says rev.AG, does not have an Initio chip on it. I figured I fried the enclosure, but wasn't too worried about about my data as I have swapped pcb's and bridge boards before, however this encryption bit took me by surprise. I then checked cords and realized the issue, tried the correct plug and it was a no go. there was a very minor spark at the plug (like a static shock sized spark) and I retracted immediately. I tried to plug in the adapter for a set of bose speakers- AC 12v 1.2a. As the title says I have a 3TB Western Digital My Book Essential.
