Hello everyone. A couple months back, I purchased this soundbar. I was having issues with the video with the DVR, where every 15-30 minutes, the video would I guess re-sync or something. It would blank out for a second then come right back up. I fixed that by connecting the DVR and my PS3 to the TV and running a digital audio cable from the TV to the main unit/receiver. At the same time as the video issues, I was (and still am) having issues with the audio. Every 15-30 minutes, the audio volume will "dip". It'll be playing perfectly, then go down in volume and come right back up. Nothing is touching the remote, and nothing displays on the screen saying that the volume is changing. Does anyone have any ideas what could be the cause? I'm trying to troubleshoot this on my own before contacting Sharp. |

How are you connecting your components together? HDMI? Did the audio issues resolve when you connected the optical output of the TV to the receiver? Do the video issues happen when you connect your video source straight to the TV as well? Both the DVR and the PS3? What I'd start with is troubleshoot the setup. Go through all the "Source X" connected to "Input Y" combinations and see if you can isolate a specific component. Also try a different cable if possible in that mix. It's not uncommon for there to be glitches on HDMI when interconnecting certain components, even with the higher-end stuff. |

"How are you connecting your components together? HDMI? Did the audio issues resolve when you connected the optical output of the TV to the receiver?" I'm about to take the DVR out of the mix, so that'll eliminate that being a possible reason for the issue. Set up is: HDMI from DVR to TV. HDMI from PS3 to TV. Optical from TV to soundbar receiver. At the beginning, I had the DVR and the PS3 going to the receiver using HDMI and optical from receiver to TV. With the setup I have now, the video issues disappeared. I've tried switching out HDMI cables, optical cable and the speaker wires. "Do the video issues happen when you connect your video source straight to the TV as well? Both the DVR and the PS3?" No. I recently sent the soundbar to the Conn's service center and I had zero issues with sound or picture. |

Quoted: Set up is: HDMI from DVR to TV. HDMI from PS3 to TV. Optical from TV to soundbar receiver. Is that the setup that's giving you trouble, or is that the setup that's OK? Which connection was giving you trouble? Was it PS3 and/or DVR ––HDMI––-> receiver ––HDMI––-> TV? If so, then it would definitely implicate your receiver as the issue. I'm also confused about the replacement receiver; is that still giving you trouble in the configuration you originally used? All of my components hook into my Onkyo via HDMI (the DVD player via component), and there's a single HDMI cable from the receiver to my TV. The receiver does video upconversion and HDMI switching. If I had similar issues then my first check would be: 1) See if the issue occurs only from a single input. 2) If not, then the A/V receiver is like an issue. Go to step 2a just to be sure. 2a) Next step would be to connect a component directly to the TV and see if the issue goes away to confirm it's the receiver. 2b) If it still does it, it could be the TV's HDMI input. switch the component to another HDMI input. 3) If it's a single component, swap the HDMI cable as a first step. 4) If it persists, connect it directly to the TV to see if it still acts up. If so, connect it to another HDMI input on the TV. Optical audio is so last year.  |
 When I was having both audio and video issues, it was PS3, DVR > Receiver > TV, all HDMI. Currently it is PS3, DVR > TV > Receiver. I only have 2 HDMI inputs on my TV, so I had to do optical to the receiver. I am listening to FM on the receiver right now to see if I have any audio issues. Been 20-30 minutes or so and I haven't heard anything odd yet. I do have the DVR unplugged from the power source, and will try the PS3 if the FM plays fine for another 30 minutes. Good thing I'm getting rid of cable, eh? |

FM radio was fine, no issues. Went to play PS3, had issues when the configuration was PS3 (HDMI) > TV (Optical)> Receiver. Changed it to PS3 (HDMI)> Receiver (HDMI)> TV and it works fine. WTF.  So I am guessing that there is either something wrong with the optical input/output on the TV or on the receiver. But that doesn't make any sense cause I had issues with both audio and video when I had the DVR hooked up and it was all HDMI. I don't get it. |

Here's what I would do . Unplug the HDMI cable from the PS3's out and plug in your DVR. See if you have issues. If you do, connect the DVR straight to the TV. If there are no isues with the DVR connected directly to the TV, but there ARE issues when the DCR is connect via the receiver, then there's a compatiblity issue between the DVR and receiver. You'll either have to live with it, or change out one of the components.

I had some real headaches setting up my DNLA network in the house.... had to go right back to basics and add components in turn... My Panasonic TV kept "hopping sources", until I replaced the Umax Blu Ray player with a Panasonic unit...
All good now |

I hear ya'... HDMI is a digital signal standard, but that doesn't mean everyone implemented it correctly. Besides the electrical specification of the bus timing, there's also analog specs that have to be met for drive strength, impedance, signal-to-noise, etc. I'm sure that when you throw together many manufacturers and cables, that you're bound to create conditions which create problems such as Compass has found out. I tell you one thing though: HDMI is a god-sent in the bigger scheme of things. One friggin cable, done. |
