Question about Onkyo TX-SR804 7.1 Channels Receiver

1 Answer

Losing digital video signal

I recently starting losing the digital signal for my HDTV from the Onkyo receiver. It started with the 3 prong RGB cable. So I changed it to the HDMI cable. But the signal is "lost" in the receiver. When I hook up the HDMI directly from cable box to the TV, all is fine. Help.

    Not sure what model I have but the same exact thing happens to me.  Wasn't sure what the issue is but it appears now that it is my receiver.

    I have the Onkyo TX-SR805 and have had it for two years and now the video keep going out on my HDMI, sound is still there, but no video. There seems to be some kind of short on the video relay to the output. Have not had it fixed yet, so can't give any answers.

    did this solve your problem. My HDMI video out first is "incompatible" to the TV, then when the Onkyo warms up, it is wavy the the picture is fine.

    Any thoughts or advice?

Onkyo receiver is not starting up hdmi from receiver to tv


run an HDMI cable from TV direct to DVD or other HD source instead of going through Onkyo. If it works, you have a bad HDMI output on the Onkyo. If not you may have a bad cable or a bad port on TV. Then try a different HDMI input on TV.

How do i get 1080i, my tv shows im only in 480i. i think i might have it hooked up incorrect. my other tv of another brand is much newer so all i did was connect the hdmi cable from the tv to the cable box...


Hello

Your TV will display all High Definition signals as 1080i True HDTV™ and all standard definition signals will be displayed as 480p.

Component Inputs 1-2
YPbPr(480i/480p/1080i)
These inputs can be used for the connection of A/V equipment with component video outputs, such as a DVD player or external HDTV receiver. Please see Appendix B for signal compatibility.
Input DTV (480i/480p/1080i)
This input is used to connect an external DTV receiver, and can be configured for YPrPb and RGB plus H&V signal types.

As a special feature, you have the ability to adjust the red and blue light beams in reference to the fixed green light beam. This process is called convergence. There are two separate memories for convergence. One, for SD 480i/480p signals; the other for HD 1080i signals. SD convergence should be adjusted while watching an SD source and HD convergence should be adjusted while watching an HD source.

Wide Expand: Enlarges the picture, cropping some of the image on both sides. This Expand format is useful to remove or reduce black side bars on HD broadcasts of 4:3 images with black bars. Available for analog 1080i, digital SD 16:9 and digital HD signals.

InputDTV
This input is compatible with most standard DTV and satellite receivers with component video (YPbPr) outputs. Compatible DTV signals are SDTV 480i/480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Please check the DTV receiver specifications before connecting.
This input is compatible with some DTV receivers using RGB with "separate H and V sync". Compatible DTV signals are SDTV 480i, 480p, and HDTV 1080i. All other DTV signals, such as 720p, need to be converted by the DTV receiver to one of the compatible signal types. Industry standards for DTV RGB signals (systems, synchronization, timing, and signal strengths) are not currently established. These inputs will not be compatible with all DTV receivers that offer RGB, HV outputs. RGB, HV signals with less than 5 cables are not compatible.
If your DTV receiver offers both DTV component video signals and DTV RGB, HV signals, we suggest you use the DTV component video signals. Check the DTV receiver specifications before connecting.
Ok.

My Sony AV unit (probably 3 yrs old) suddenly switches from all 5 channels to just the two front without warning; I can push enough buttons to return it to all 5, but sometimes it switches back and forth...


You don't name the model but if there's asettign for audtomatically selecting digital vs analog when both are attached it's losing the digital signal and automatically switching to the analog feed. Find it in the manual. lacking a setting, it prefers digital over analog and will switch to analog on digital signal loss.

Analyze what source(s) are involved and investigate WHY you're losing the bitstream. Optical cables must be run with smooth loose bends so the light strength is not compromised.

A/V Signal Outout through Onkyo TX-SR705


Are you trying to record cable programming with your DVD recorder? If so, you might want to try using component cable as HDMI does have a copy protection circuit that might be preventing your recorder from receiving the image. Just try to connect the cable box component (RED/GREEN/BLUE) cable to your DVD recorder. If that doesn't work, then try to change everything over to component cables. HDMI is a great cable to use but it the only required to display 1080p images and the only current source that uses 1080p is a bluray player. Everything else, such as your cable box and DVD recorder is 1080i and component cables are perfect for it.

Component Video losing sync with too much White signal


I had this exact same issue. I tried two different component AV switches, and shorter cables to prevent signal loss, but any time there was too much white on the screen, the video still lost sync. Plugging the sources directly into the TV solves this problem, but since I have a DVD player, a game console, etc, this was not acceptable. The way I resolved it was to (sadly?) buy an expensive component AV switch that can support the bandwidth without losing the signal.
I wound up spending the extra money on a Key Digital 4x1 component switch. It is much more expensive, but it works.
