I just turned on the TV this morning and there is no video display. Only audio.
Audio works fine.
I tried rebooting the HD box and reconnecting HDMI cable on both the TV end and HD box end.
When I turn on the TV the video would display for 1-2 seconds and goes black
I had the same problem in the garage and I rebooted the HDbox and it started working fine.
Am I supposed to always leave HD box turned on?
Does this happen every once in a while?
What trouble shooting can I do?
and I dont know if this matters but my HD boxes are P3 and the old owner had P2, which is why for every HD box I wanted to connect to TV, I had to call shaw and had someone come and re-route the cables.. because with the existing setup, the TV did not get any signals.
