LED Does not Remain Lit

[KaranP]

When I plug in the power supply that came with my kickstarter pack, the pine64 will show the red LED for about a second before it fades to nothing.  It does the same with other cables.

Is there any other test to try or is this DOA?

The red LED directly link to power input, please check your power supply or try another one.

It does the same with other cables and power supplies that I have.

Sounds like some place short circuit and cause the power supply trigger the protection. Please PM me and I will make a replacement.

I have a very similar issue. My board turns on with HDMI connection, however it only stays on for ~15 seconds before the LED light resets and then it reboots. This process keeps over and over again till I disconnect the power source. 

I bought the cable accessory and charger accessory. Both produce the same result. Do I have a defective board or am I just missing something?
