I've had Optik for about 10 years without issue. In July the Arris 4K PVR box started acting up & was replaced by Telus. When I would turn it on the TV would the Optik box would come on too but I would get a black screen. Sometimes the guide would show, but would not go to a channel, just a black screen. More often than not the guide wouldn't show, and none of the other buttons would do anything either. The link & power lights were green and the power light would flash as expected when pushing buttons on the remote.
Sometimes I could get it to work by turning off TV & box & turning on again, but it would become more frequent and harder to get working & then eventually not work at all. I rebooted everything TV, modem optik) but no change.
I called Telus & did troubleshooting but couldn't resolve it, so they sent a tech with a new one. As soon as I hooked it up it worked perfectly.
A few weeks ago, it started doing the same behaviour (black screen when turned on) and a couple times said something like "please wait, PVR is starting" when I tried to record something (1st time to see that message ever). Now I get nothing but black screen. Telus is coming tomorrow to fix or replace, but am stumped as to the cause. Anyone else experienced this or have any ideas? Seems odd that 2 boxes would die in 5 months.
The optik box is connected to AV receiver and receiver to smart TV all by HDMI. Everything else works perfectly (all smart TV functions, blu ray) just cannot watch TV...
Have you bypassed the AV receiver and connected the Optik receiver direct to the HDMI port of the TV bypassing the AV receiver?
This way you truly rule out the Optik box and not being an issue with the AV receiver handling the handshake. There has been plenty of posts over the years on various video issues.
