Hi there, hope someone can assist. I have a neo sync box 2.0 and was working perfect for about 2-3 days. the hdmi not doesn’t work and my tv displays weak or no signal. I’m using a roku ultra and have changed the cables and still not working. Have plugged the roku straight into the tv as well and it works perfectly so definitely is the neo sync box. Tried resetting and reconnecting it but still won’t find the hdmi signal from the roku. Any ideas?


Hi there.
Have you tried other HDMI cables? And it would be better to use a shorter HDMI cable. It might also be related to the length of the cable. Too long HDMI cable can also cause signal instability.
I notice the light and the sync box can light up normally from your first video. Therefore, it might have some issue on the OUTPUT to your TV side.
