I have a Vizio P702UI-B3
I'm using a Harmony One remote to turn on my Hopper3, Onkyo TX-NR646, and the Vizio. Never had any problems...
Then sometime in the last 2 months or so I started getting a static/snow-filled screen
on the Vizio when I powered everything up.
Audio was coming through the amp (the Hopper was on and working), but it's like the Vizio couldn't "lock on" to the HDMI signal or something (it's on the right port - HDMI 1)
For a BRIEF moment during the Harmony sequence, after the Vizio was turned on, I would see video on the TV, and then it would switch to snow (it powers on and is then sent the "HDMI 1" code)
To fix it I just have to hit another input (like HDMI 2) and then switch back to HDMI 1
Has anyone heard of a recent firmware update for this TV causing something like this?
I've been experimenting with turning the Vizio on EARLIER or LATER in my Harmony commands, but this issue still happens maybe 1 out of every 5 times, and my WAF is quickly plummeting! HA!
