This one has been around for a very long time & I'm kind of surprised it has not been resolved by now.
When first bringing up the standard view TV, none of the images for any channel shows up... UNLESS I click on the channel, move to another channel, than click on the first channel a second time. Each & every time the first click on any channel brings up a blank where clicking on another channel, then clicking on the first channel for the second time will always bring up the image for that channel.
The text for all channels does not act like that, it simply shows up as soon as I click on any channel, would like the channel images to do the same.
