Is my Rock64 is dead ?
#1
Hi, I have a problem with my Rock64 and I would like to know your opinion and if it is possible to find a solution.

Until 2 months ago, I was using my Rock64 as an Android TV, it wasn't constantly plugged in. Then I couldn't use it since, so I put it in my desk (in a drawer).

I now have time again and I would like to use it again except... there is a problem. When I plug in the (original) plug the all the rock64 LEDs start flashing, and nothing happens on the screen, on the power supply I can hear a little "click". So I thought that the problem came from the power supply, even if it's strange, I made a multimeter measurement, I have 5~5.2V at the output.

I then checked the physical integrity of the ROCK64 and except for a few strange little "dirt" (because it was well stored).

I can't tell if it is rust or not, it's strange, inside a desk and there is no "water source" or anything near.

Tested with and without SD Card, with and without emmc and it still the same.

Do you think i can do something to fix it ? i love that device, i'm so sad it's not working anymore, I've always made sure to store it properly so it doesn't get damaged and in the end I feel like it's worse than better.

from photo, can tell what type of dirt. The location is close to USB 3.0 host port, if affected, should be only USB 3.0 not working. If you have serial console, please check on boot up log message to determine where is going wrong. If you don't have serial console, then just reprogram OS to another microSD card to check whether able to boot up again.

Hi, i cleaned the dirt this morning, i don't think it was some rust or anything, it's very strange...

I don't have a serial console. I tried with a SD Card (witch don't contain any OS), with the EMMC (with android 7.1) and with nothing. I've recorded some video, maybe it can help

With the EMMC only





With the SD Card Only  :

And without any storage :

As you/i can see it's always the same, i can also hear something coming from the rock64, i hope we can ear it on the video

PS : It's not a issue with my phone, all the leds are blinking

The green LED not suppose to blink. When blink, it means the ROCK64 somehow withdraw a lot of current from power supply that cause power supply trigger its over current protection circuit, or another situation is the power supply itself may suffer some defect. This is the guess finding from your short video.
