[ZedBoard not turning ON]

From your description we suspect that something is broken between J20 and SW8. A simple suggestion is to remove the fuse (F5) and replace it with part 0603SFF500F/32-2. If this is not possible you may try to short it.

Oh the LD13 light is on after shorting the fuse! I guess the blown fuse is exactly the reason. I'll order the same type to replace it, thanks so much!

Hi @Shiv,

What values do you measure across the capacitors that were mentioned in this specific post?

Do the power good LED light up when you connect a 12V power supply and turn on the Zedboard? Is the board detected by your operating system? What revision of the Zedboard do you have?

Thanks,
JColvin

Hello @JColvin@jpeyron,

I'm facing with exactly the same issue: I suddenly could not power on my Zedboard, which worked pretty fine last month. Just after bringing it to Washington this board failed to start, which was really weird.

The LD13 power light doesn't flash, or to say I can't detect any valid power stages for the capacitors mentioned above. The adapter works since I can detect 12V using DMM on J20 port, but there's no voltage on the switch (SW8) when turned on. Btw I just recognize there's a 8V voltage on element F5, which seems abnormal.

I'm using Rev D version, and this board was purchased an year ago, around Mar. 2020. Please kindly provide any suggestions! Thanks in advance!
