I apologize if this has been discussed but I cannot find an exact issue match when I search. The issue I have is with HDMI from my rented 8300HD to a brand new LG LED TV. The picture will remain great for days at a time but occasionally, when i switch TV inputs and then back to the HDMI from the 8300, I will lose the video signal; no error messages, no HDCP warnings, just the video popping in and out as if it is trying to "sync". A cold reboot of the 8300 seems to solve the problem (for a few days at least). I've tried various HDMI cables and HDMI inputs but the problem seems to follow the 8300. Is this an HDCP issue or just a faulty 8300 (before the new TV I used component without a problem, but would like to use HDMI because the TV is 3D capable). Does the 8642 cable box offer a more stable HDMI output? Any help would be appreciated.

There could be an issue with your 8300 HDMI port. The 8642 is not really more stable, but is newer.

Here's the HDMI FAQ with a list of things to check (like startup order).

You should be able to get 3D with component video, I believe it's on Channel 900 and side-by-side.

Thanks 57 I will review all of this, but i too feel it may be a problem with the 8300 HDMI port. Unfortunately, on the LG TV at least, component or composite only gives the option for 2D to 3D conversion. For broadcast 3D as on channel 900 you need HDMI to enable side-by-side.

As a follow-up to the above, I would like to thank 57 for his link to FAQ-HDMI Comments/Issues. Item 23 seemed to be the issue; although my LG TV showed a picture with 480i, the manual specs stipulated this input should be 480P,720P,1080i or P only. Changing the Rogers box to output only 480P for SD and 1080i for HD seems to have solved the stability issue.

Thanks for the feedback. Always good to know the cause of an issue. And thanks for letting me know HDMI is required for 900/3D.
