I own my 8300hd (not rented)
About 3 weeks ago I started to get a "black screen" on power up which a reboot seemed to fix
Now I find if I just power on and wait it eventually comes up.
Rogers have been in a number of times to try and diagnose the problem but have not solved it. (they have focused on signal strength / problems)

I decided to look at the diagnostics and I find the following:

On power on, diagnostics screen 5, current QAM
Status is "unlocked" and amber
EQ Gain is 0.000000 and red
screen is black.

If I just leave it and wait: EQ Gain starts to switch back and forth between 0.0000 and 1.0000 eventually staying at 1.0000 and then the status goes to locked and I have a picture. It now stays good as long as the 8300 is switched on. I can power off for short periods of time but once it has been off for a number of hours the process is repeated.

Question: does this sound like a problem with the 8300 or a signal problem?

If it were a signal problem I would guess the picture would be lost at random times during viewing. If it only happens when you power up I lean towards a problem with the 8300 PVR. Sorry...

What are the signal strength and S/N ratio? It's possible that once the signal is "locked" that it'll be OK until the signal is lost again after a longer power down. Black screen is certainly an indicator of a poor signal, although something wrong in the STB could also cause it - say a poor connection at the RF-coax input. Can you try the unit at another location in your home? Temporarily remove any splitters upstream?

The other thing to try is, connect another box to that outlet and see if it is experiencing the same problem. If so, its for sure something with the line.
