This is a really odd one. I've done a ton of troubleshooting, and can't figure it out:

I am running this receiver with an Epson projector, DirecTV box, Sony 4k Blu-ray player, Xbox 360, and Amazon Fire stick. We were noticing periodic drop-outs of the HDMI connection when viewing content on the PJ. The problem consistently got worse. It is somewhat intermittent, but at it's worst, it drops out once or twice a minute for 5 to 30 seconds at a time. I am using high quality fiber optic HDMI cables. I can consistently reproduce the problem with one trigger in particular: if I shut off and restart the HP network printer that is in the same room as the AV gear, the HDMI drops out for about 5 seconds. I have connected an HDMI source directly to the PJ, and also through the fiber optic cable without using the 3060 reciever. In both cases, no issues when the printer cycles. So the PJ and the cable do not appear to be causes. But when the signal goes source -> 3060 -> Epson PJ I get the drop outs. The common link is the 3060.

The AV equipment is on it's own circuit, so power should not be an issue. Could some sort of network issue be the problem? I tried disconnecting the ethernet cable from the 3060 but that made no difference.

Update: I think it has something to do with the DirecTV input. I tried various combinations of HDMI inputs connected and disconnected from the 3060. When the DTV box is not connected, I have no issues when the printer cycles. If connected, the HDMI drop out occurs when the printer cycles.

The issue also occurs when I turn on a hair dryer connected to the same circuit as the printer. But again, only when the DTV input is connected to the 3060. I have confirmed that the AV equipment (all of it) is on a different circuit from the circuit with the printer and hair dryer.

I’m no electrician, but your satellite dish and RG6 cabling running from your dish to the DirecTV receiver might be somehow “connecting” your AV circuit to your printer circuit. Some DirecTV setups even have something plugged into power that the RG6 cables connect to when they come into the house.

Unplug the RG6 cable from the DirecTV receiver and test again.

Laser printers are noisy and generate lots of interference. It's possible it's being picked up by something and interfering with the HDMI signal causing the dropouts. It isn't being picked up by the long cable from the receiver to projector as it's fiber optic, but likely from the source to the receiver which is standard copper.

Best option would be to move the printer - to another room on another circuit would be ideal. This is especially true of the printer is a printer designed for office use rather than home use - office use printers have relaxed interference criteria compared to home use equipment (it's why you sometimes see stickers saying "not for home use" or "for office use only" on equipment).

Mine just up and died...Does yours make you do a firmware update every 2 months? Mine was before it died.

Unplug the RG6 cable from the DirecTV receiver and test again.

I unplugged the RG6 and that stopped the drop outs. However, that obviously is not a solution, since I can't watch TV with the RG6 diconnected. It also does not explain the root problem. It could be some type of voltage fluctuation, or a network issue, since my DTV receivers have wifi access for on-demand viewing and remote programming.

It is a printer designed for home use. It is already on a different circuit from the AV equipment, which is the confusing part. The printer is, however, on the same circuit as the wifi router. I may have to move the router to a new circuit and see what happens.

I have not done a firmware update on this receiver in more than a year. Could that be an issue?

SOLVED: @Augie was onto something. There must have been some interference coming through the RG6 cable. I ran the RG6 through the coax connection on the surge protector that serves all of the AV equipment. So far, that has eliminated the problem. I am still not sure if it has something to do with a voltage fluctuation or a network issue. I am leaning toward a network issue, since the router, modem and one of the switches are connected to the same plug as the printer. Thanks for the help!
