I posted the following on Satellite Guys forum late yesterday and this morning, and as yet haven’t resolved the issue.
When I switch from channel to channel on my E* 622 receiver, I will first get a gray screen, then it will flash to the usual black before the channel tunes in. Try it again and I may get a 4:3 image (black, with gray bars on both sides) flash to gray (sometimes), then to black (sometimes), to finally being tuned in. This started last night. I’ve tried 3 inputs on my TV and I’ve swapped the HDMI cable. This does not happen when I use my TVs coax input for OTA. I rebooted with no affect.
I tried OTA through the 622 this morning and it did the same thing. Also, satellite channels were doing it consistently this morning.
Now this was really weird. While watching MSNBC this morning, there was a promo for Showtime, it went to 4:3 with gray bars on the side, and when that finished, the screen went to gray then back to Morning Joe. So in this instance it wasn’t a channel change, it happened during a commercial break.
After owning the TV for over a month, if it were a handshake issue, why would it show up now, and be sporadic at that? And between commercial breaks? This is really puzzling.
