Received a new T3 today which was a replacement for an older model. I think it may be DOA. I plugged it in and the light was flashing green/red and then went solid green. I tried on two different TVs with different HDMI cables and signal not detected. I believe there is no output from the HDMI on the T3.
I do have a T1,T1 plus, T2 and a T3 and have never experienced something like this before. Typically it come right on and follow the set up instructions.

Any suggestion or experience in correcting?

Thanks
