    I have a new Pioneer SC-LX502 and a C61K (Sony 940 4k TV) and its flickering (Intermittent Black Screen Flash). On DIRECTV website people have called support and found that it’s a problem with the C61K receiver. Connecting the C61K to the 4k TV solves the problem sometimes. I had a Yamaha receiver that supported 4k, but not with C61K. The C61K would only do 1080P while connected to the Yamaha receiver on channels 104 and 106. Before upgrading to the new Pioneer SC-LX502 I did not have this problem. It is possible it is a HDPC 2.2 copy protection problem. I have upgraded to Monsters Ultra 4K HDMI cables that have 21 GB cable version. I’ve tried about everything I could do with the SC-LX502. My understanding DENON and PIONEER 4K receivers are having problems like this. I will connect it directly to the TV and use OPTICAL until it is fixed.

    I have a new 2017 Vizio P65 and new C61K and I get the intermittent black screens (usually lasts about 2 seconds) - even with the HDMI connected directly from the C61K to the Vizio, bypassing my Onkyo AVR that does not support HLG pass through.
    This is on Ch. 106 watching World Cup games. Doesn't seem to happen on every game, but I'd estimate I get about 2-3 "black-outs" per game on average. So not enough to stop watching the games in 4K/HDR, but enough to be annoying!

    Would love if someone here, or DirecTV, could come up with a solution for this!!

    I would try to find some HDMI 2.0/HDCP 2.2 box (splitter/switch/etc) what has quick negotiation time and install it in-between

    I have a couple of 2.0 HDMI switches that I could try. So my guess is that I would put this between the DIRECTV receiver and the Pioneer SC-LX502? I wonder if I would have the same issue with the old receiver doing 1080P and not 4k?

    I would try simple path - between TV and mini

    Called DIRECTV technical support and the call center and they sent a technician to review the flickering and document it for our account. The technician already knew about the issue and watch it happen on my 4k TV's. He believes it is a Genie 2 issue and not a C61k problem. Connecting C61k directly to Sony 4k and using optical cable for sound via the Pioneer receiver does solve the problem temporarily. The receiver has the technology to control high loudness from TV shows and this feature does not work very well with optical cable connected. The last Genie 2 update was on 6/6/2018 but did not solve this problem. I hope to test with a HDMI switch this weekend.

    Is the optical cable ran from the TV or the c61k ? If the TV, I would switch it. Use the c61k optical out to the Pioneer.

    The clients only have coax digital out, no Toslink.

    Does your Pioneer have digital coax connection ? You might try that.

    I think your reply was meant for Hellrider. I was just pointing out that the clients only have coax digital out. :thumbsup:

    Anyone that has the latest software update (1103?) - has it helped at all with the black flashing ? When I looked at the DTV Firmware Watcher yesterday, it looked like 1103 was in the stream for the HR44, HR55 & HS17 but today it shows 1088 again.

    Thanks, I wasn't completely sure of the version. I had been expecting my equipment to get the update, but looks like it won't be happening just yet.

    National release is 1088. 1104 has been available in the early hours of the morning, has been an automatic download for some but others have initiated a download themselves. We could easily have more of these interim releases before there is a new national release.

    Does anyone have 1104 that has experienced the black flashing - is it still happening ? I'm still on 1088 and have been experiencing more black flashes and picture freezes than previously. I'm may try resetting all the devices tonight to see if it helps, but I'm really hoping 1104 makes a difference (probably won't though :().

    I got 110b a week or so ago, about the same time my UHD 104 black screens stopped. I can’t be sure the older firmware was the problem, or if the new firmware is the fix, just that I haven’t seen any black screens in a week or so.
    Haven’t see 110D yet, as I mentioned 110b seemed to help me.

    You are correct, it is 110b, not d. Unfortunately, it doesn't seemed to have made any difference to my black flashes. I'm really starting to think it might be specific to my Sony tv (x930E). The flashing/freezing does not happen on my Samsung Q8 tv. Both tvs are connected through Denon amps to the C61K boxes. The amps are slightly different (Avr-x3300 for the Sony vs. Avr-x3500 for the Samsung) but it's too much of a pain to move those around to see if it helps.
