Question about Onkyo HT-SR800 System

1 Answer

Video disappears within 30 seconds

First of all let me say that i am a firm believer in "user error". I hope that this will be the cause here.

I have just finished setting up my new HT-SR800 system (I gift from my son) and I have a problem.
When i try to watch something from the Cable Box or the DVD, I lose the image within 30 seconds. Most of the time I don't see any video; occasionally I do but i lose the image within 30 seconds. I see the video only when I turn on a device, but i can't reproduce the problem. That is, I intermittently get video upon start up, but most of the time there is none. This problem appeared after I finished the setup (I added the Onkyo DVD Player) and moved all the pieces to their final positions in my TV stand.

I know that there is continuity in the connections since I was able to watch Cable TV last night. I know that the connections still work today, since I see the video briefly. As I mentioned, today I added the DVD player into the mix. However, the problem continues to exist even if I unplug that device from the receiver.

My connections are as follow:
1. Receiver to Sony HDTV -- HDMI Cable
2. DVD to Receiver -- HDMI Cable & digital audio via an optical cable.
3. Cable Box to Receiver -- DVI/HDMI Cable & digital audio via an optical cable.

I am frustrated by not being able to fix this. My wife is peeved that she is not able to watch the big TV. Furthermore, I am irritated that I had to troubleshoot this rather than watch the OSU/LSU game.

I would appreciate any help that you can provide.


(As an aside, is it really reasonable for Onkyo to say they have HDMI connections if they do not implement the audio portion of the spec? It's really DVI with copy protection and different/worse connectors. I was irritated that I had to purchase the digital video cables that my son neglected to supply.)

Re: Video disappears within 30 seconds

Hi Mark

I am going to take a stab in the dark here...

Did you plug the hdmi from the receiver to hdmi via the monitor hdmi output? this is needed so when you change the device on the receiver ie. between setop box and dvd the monitor changes with it accordingly.

You may also need to go to the setop box to set it to use hdmi output at the right frequencies 720p 1080i or 1080p.Also set it so it only sends the picture via hdmi but audio still with optical out.

good luck

After transferring a vhs to dvd there is a motorboating sound on dvd during playback at about 10 beats per second... any ideas

This is very interesting. Usually it is an electric interference.
1.) Most often it comes if you use a cheap mouse. First I'd change the mouse (sounds silly, but when I was talking via Skype with a friend he said he hears the same sound you described). Try another mouse, borrow one or just disconnect after recording has started.
2.) Use GOOD cables for video AND audio. Not those thin ones. A good cable is at lest 2x shielded. They are about 4-6 mm thick.
3.) Routers can make the same interference. If your router is within half a meter near to you PC, it can cause the same problem. Move your router at least 2 m away from your digitizing device.
Hope I could help!

I have installed the v30 bose lifestyle system but I can not get any video output on my Samsung led tv. I have tried the hdmi cable and the component cable. It both doesn't work.please help me with this

I recommend you stick with component cabling.

Having no picture at all generally suggests the V30 is trying a video mode your TV does not support:

  1. video type (PAL or NTSC)
  2. Progressive scan
  3. an HD resolution beyond your TV's range.
I hope that helps.

When playing a dvd it black and white no color

what output connection are you using? (svideo can cause this if it's not properly supported on both devices)
What format is the video stream NTFS or PAL? some devices don't like one or the other format. This issue could be linked to your dvd player or your TV so please investigate what I have suggested and post back here if you have no luck :O)

The first solution is wrong. (no offense to the Guru) This can not be caused by any settings, so save yourself the hassle.
The LS38 does use RF and IR, but if the remote works at all, RF is already active. 'IR control' is only for using other universal remotes on this system.
If shaking the remote does not cause a rattle, then there's probably nothing wrong with the remote. Also nothing wrong with any dip switches. (I'm assuming you've tried new batteries)
The power supply cable (DC power) at the back of the media center also doubles as the receiving antenna for the RF remote. Straighten this cable out as much as possible. Make sure it's not wrapped around any other cables, power cables especially. This should solve your problem.

Sign in problem in yahoo messenger

I believe that your login should be the same as your Yahoo Instant Messenger login info., so verify your username and password and try them to login to YIM.
If not, when you're notified of the login error, there should be a link for forgotten Username and/or Passwords within the error notification if U.N or PW are the problem.
Good luck.
