Not really sure how best to describe it. When we watch TV every few minutes the screen turns black like the nextbox is turning off and on, but it resumes on the channel I was watching not channel 1 like it does if I manually turn the box on and off. The black screen lasts between 1 and 2 seconds.
Not sure if this is related but the day before a program I was recording wouldn't stop, even when I turned off the power. I had to unplug the box to reset it and stop the recording, but that's when the problem started.
Yes, you're right. The power light isn't turning off and on. I just find it weird that this has happened all of a sudden right after another issue. I'll try your suggestions when I get home tonight and see if that helps. If not, is this an issue that Rogers will replace my box for, do you think?
As @Gdkitty and @robindp suggested, the intermittent black screen issue can very well be caused by a bad HDMI cable or a bad HDMI port on the box. I've also seen an issue where customers have the box set up in such a way that they had connected the HDMI cable from the box into a home theatre unit, and then the home theatre directly into the TV. This can also cause an issue like this. The HDMI cable should go directly from the box to the TV. Best option as suggested would be to try and switch HDMI ports on the TV, or try a different HDMI cable to test and see if it fixes the issue. If not, you can always swap the box at a Rogers retail location or have a technician booked to swap the box which can take a few days depending on technician availability and how booked the calendar is.
