818 Lines flashing across the screen

I just purchased the 818 recently. Sometimes when I switch video inputs I get 2 or so white lines flashing across the screen. I have updated the firmware, and checked my connections. It happens once or twice a day. It happens on different inputs, and all are by HDMI.

Is this a know issue, is my unit defective, or should I be doing something different?

Thank you for your help.

Hi Ddean,

I have found and with helping others on this board with success. Unplug the unit from the power supply for exactly 5 minutes. This is considered a "soft boot"; you will NOT lose any of your settings. After you have it unplugged for the 5 minutes, plug it back in and see what happens. After it is plugged back give it a min or so, and then turn the receiver on and hopefully this will help.

I have the TX-NR717, had a few issues that for the life of me could not figure out, flashing like you are saying. after a firmware update. Found and did this. My TX-NR717 has been working like a champ ever since.

I will always do this after a major update. It makes sense if you think about it. PC's, Cells, Tablets all reboot after an update.

Hope this helps. ENJOY!

Post here and let all know if this works. If not, contact Onkyo for assistance.

Thank you for your reply. I tried what you said and went to work today. Came home and was switching inputs depending what I wanted to do tonight.

I saw the flashing lines going across again. I was a little miffed, but I gave it 30 seconds or so and it went away on its own. Think it might be a handshake issue between devices that fixed it self? I'm not sure. Just don't want a defective device.
