ZedBoard does not power on

Former Member
Former Member over 11 years ago

I've only had it for a day or so... It was laying on my desk (powered on because I was watching the SPI connection), and the green light went off. The power jack on the board is still getting 12V, there is 2V across the green LED, but the light isn't on. The board is not recognized by the computer (it's not on, as far as I can tell).

What should I do now? Could it be a fuse?

Edit: The voltage across the green LED seems to change a lot. Right now it's 1.2V, I've also seen it at about 0.3V.

Edit #2: There is an 8V drop across F5 (fuse 5?). Across the power switch there is only 4V, even though it should still be 12V at that point. Think I can just bridge it out if I can't find a replacement for now?

Edit #3: Pretty sure it's F5, the resistance across it is 33Mohms. So the question is, can I short it out for the time being?

    I ended up shorting it out for now. I'll just have to be extra careful with it today/tomorrow. I ordered replacement fuses - if anyone needs them and stumbles upon this thread: F5 is replaced by these: http://www.digikey.ca/product-detail/en/0603SFF500F%2F32-2/0603SFF500F%2F32CT-ND/686745 .
