What an explanation James.
I do have same kind of problem, I'm using HDTV and Yamaha amplifier, everything connected to my amp and only 1 cable from amp to my tv. All connection using hdmi.
The flickering sometime happened about 30sec, the display at the decoder show 'decoder off' instead of Dolby digital.
This only happened with hd channel, not all of the HD channel. It occurred mostly when I watched espn hd, hbo hd & nat geo hd sometimes..
What would be the prob, is it my hdmi? I never tried change my hdmi cable, I'm using normal one that I bought from challenger around 50-60 bucks
I am not too sure in your case but I do believe that sometimes there may be "handshaking" problems between the Byond HD and the amplifier. I
think handshaking involves communication and identification of the HDMI signal between the two connected equipment.
NEW ADDITION
If you haven't, try not to use amp to test and connect Byond HDMI directly to HDTV to see if flickering still happen.I will let you know my situation which have similar "small" problems as yours. My Byond set is also connected by HDMI to my Yamaha RX-V1900 amplifier. Then from amp HDMI output to my HDTV.
Ok... in my case. Whenever I switched everything on and Byond is first tuned to an HD channel (can be any HD channel), my Yamaha amp will always flash on the amp display panel many many times and also the HDTV too. This flickering and flashing of the HDTV screen and the amp panel display will ALWAYS last about 20 to 30 seconds and after that, everything is fine. Its like my amp is trying very hard to grab the Byond HDMI signal. Once it managed to get connected, then all is ok. What I did is always quickly tune the Astro to any SD channel immediately when switched on. Then my amp immediately "caught" the signal and no flashing at all, and then I changed to any HD channel. Problem solved. No more flashing in any HD channels I tuned as long as my Byond set is on. The response I got when I called Astro Cust Sup is that maybe its my amp and told me to refer to my amp dealer, lol !
My Yamaha amp have no such problems when I use my Dune Smart D1 media player, Sony blu-ray player and Oppo BDP-93 player.
Used many different HDMI cables such as the cheapo ones to Audioquest Forest and Pearl, to QED Performance but still the same thing happened !! I always have to change to any SD channel first before I switched off the Byond, then when switched back on, it will be at the SD channel and my Yamaha amp can "grab" the Byond signal immediately, no flashing and no flickering, and then no problem changing to any HD channel. Funny, isn't it ? Could it be my amp got problem with the Byond HD output signal ? Maybe.
Another friend of mine in Temerloh, Pahang also reported to me the exact same problem as yours which only happened for any HD channels !! Sometimes his LED TV also flashes a few times
while watching ANY HD channels. No problem with any SD ones! Its funny that this happens mostly on
some HD channels in your case.
I am starting to believe that with my own "problems", my friend's problem and now yours, I somehow suspect it may not be our amp or TV that is causing the flashing problems. The culprit may be the Byond box that may have compatibility and handshaking problems in its own software. This is only what I personally believe and
I can be wrong because I am
not a technician or an engineer. I do hope Astro have corrected such compatibility "problems" with the software update that is now ongoing.
I am not sure if its software problems but its also known that software compatibility can cause unique problems. Even the Oppo BDP-93 did have problems such as playing the EU blu-ray release of "Kung Fu Panda 2 (BD, 2011)" where disc playback will automatically stop once you go to the disc Main Menu and select PLAY. Their latest 65-0302 Official firmware (06 March 12) corrected this problem. Luckily I don't have this disc to play in my Oppo BDP-93.
You can try changing the cables as I don't know if its the HDMI cable that is causing your flashing problem. Anyway, just don't blame me if you spent and wasted money on changing different cables and the problem is still not solved.
At the moment I am guessing only and pointing my finger to the Astro Byond box. My advice is you call Astro Cust Supp and ask them for help or let them know. The more people who have such "flashing" problems with HD channels report to Astro the better so that they know that their Byond software got HD problems. I don't know whether it will effective or whether astro software engineers will take action to correct the bugs.
I am afraid I am not much of a help to you or others who have such similar problems.
Over and out.
NEW ADDITIONSince your amp is Yamaha, it should be similar to mine. Set your Yamaha to "STRAIGHT" not "SUR. DECODE" or set "Pure Direct" to test. Try to use only 1 HDMI connection to only one assigned button. Example... Byond HDMI connected to [CBL/SAT] on amp, don't connect any other connections such as component video, optical or RCA to the same [CBL/SAT] amp input. In amp on screen Input Menu for [CBL/SAT], in "I/O Assignment" only assign the HDMI input correctly, ALL NONE for Component In, Coaxial In and Optical In. This absolutely makes sure that there are no interferences from other connections to the same [CBL/SAT]. Just my opinion as I am not sure if this is the cause. Maybe my amp is older model, but my amp display only shows nothing not "decoder off" when flashing occurs, and once connected it shows "Dolby Digital".
