MK802 III black screen problem

Postby zilbermm » Wed Oct 16, 2013 5:08 pm

Hi,

I've just updated to the latest firmware and it looks pretty good. I connected the device to my receiver HDMI input and it's powered with a 2A supply.
The problem that at the first few minutes it keeps displaying a black screen every few seconds, the black screen remains 2-60 seconds. After a few minutes the problem disappears BUT the WI-FI connection becomes slow. Youtube playback is very laggy and flickers while it finally plays.

Help?

Thanks in advance.

The black screen sounds like a signal issue between your device and the HDMI port. The wifi problem could be due to the firmware upgrade as a lot of people have reported wifi issues with the latest FW.

If the black screen problem is a signal problem, how come it becomes stable after a few minutes?

In that case, you could check the solder on the GPU, there may be a dry joint, only settling down when it heats up.
