This just started happening in the last day or two. My obi100 is blinking red and sometimes rebooting. Then it sometimes registers fine only to reboot and blink red again.. any ideas?
update: I replaced the power supply with one from a different unit and it seems to run fine now. Are the PS warranteed?
You probably will have to return the whole unit. I doubt the seller would be setup to replace just the PSU. Why don't you call them and ask?
Newegg requires you to pay the return postage, Amazon doesn't. I returned an OBi110 to Newegg and it cost me about $10. For $10 you can probably but a replacement.
I have a couple of 12V PSUs from an old modem and router. They seem to work with the OBi110. I reverted back to the original PSU, so I did not test long term.
