Mini M8s HDMI issues

Quote from nanashikun

Hi,
I have a Mini m8s and ever since I found libreelec for it it was everything I needed. But since earlier today the little box has been acting up: every few seconds-minutes the HDMI signal is lost and my avr gets a reconnect. Often this is announced by erratic lines on the screen. This is what I tried so far:
update from 7.0.2.006 to 007 - no change
reboot into nand to check if android has the same issues - check, same problem still persists
check cable, temperature, power suply, power cycle - check everyrthing looks normal
checked if other devices work normal with the avr - check everything behaves as it should

so it seems to be an issue with my mini m8s but I still have hope that one of you knpws how to fix it

thanks

First thing is to try different HDMI cable.
Secondly is it working OK just with box straight to TV . Not sure what AVR connection means with your set up.

If its a generic box I've found some of the HDMI connections on the box arent great.

You somethings have to rest the hdmi cable end on something so it makes a good connection.
