"Didn't see any info about this in the original post, but I have a 4061f TV that is having the HDMI "handshake" issue, where once in a while it can't find the HDMI sources, in my case DVD and PVR, that are connected. The audio has also dropped out in the past while playing through HDMI."
I'm new to all of this, but I cured my 4061's (PA/Oct 1036/1011) similar problems by changing the HDMI cable running from the Motorola 6416 DVR to the tv. The Verizon installer had hooked it up with a beefy 10-foot cable that worked perfectly for a day. When I began having problems I replaced it with a $6 6-foot 1.3a cable from monoprice that fixed everything. (I thought I had to supply the cable, so I ordered 3 from monoprice after spending some time here browsing. Thanks y'all. Why 3? I dunno. They were only $21.)
The tv had worked just fine for 2 weeks with the basic-service Comcast cable screwed into the back. I had FiOS installed this past Friday and everything was great. Then I posted here about not having any problems and the jinx hit on Saturday.
I had no-signal start-ups and vivid flashing pink screens, but the most annoying thing was the half-second audio drop-outs - averaging about 2 per minute sometimes they'd run in bunches of 2 every 5 secs.
I'm keeping my fingers crossed, but so far so good.
