Thanks for replying so quickly. It doesn’t power up and no LEDs are on. The focbox was given to me by someone because it doesn’t work. I am just formatting a computer to make sure that it won’t connect using windows either (I use linux).
I have attached a couple of photos of the diode being tested just in case I’m doing in wrong.
So, I got the diode off. It didn’t want to leave the board; it was very effective at sinking the heat away from the solder.
The diode is good I think: reverse biased 0L and 0.6v when forward biased on diode mode and 16 M ohm when forward biased on resistance mode.
The interesting part was that both of the pads are shorted to ground…but where to go from here?
As an aside, what would be the recommended method for removal? Mine wasn’t optimal by any means…preheat the entire board a bit first? hot air?
I used the iron with a fat tip but even the solder wick wanted to stay on the board!
Thanks Johnny…I was secretly hoping that you might chime in here having seen your previous posts
I’ll get those mosfets off and see if that’s the problem. What technique do you use to get them off without blasting everything in the area with a heat wave?
I have Q1, Q3,Q4,D101 and R1 off the board currently. Q1 and Q2 have source to drain resistance of 0 ohms (and I destroyed Q3 with too much heat). I assume that those mosfets have died. Is that a correct assumption?
