Help with Onkyo 805 issue

[eddiwill9]

This unit has been a rock solid performer for about 2 years... until I switched my HT on this evening.

I have a Comcast HD DVR, a PS3, and an Apple TV, each connected to the Onkyo via HDMI cable. I have the HDMI cable running from the Onkyo to a Panasonic projector. All have previously been great together.

Now, it appears several things are happening, which is confusing me as I try to isolate (though I fear it's a major issue with the Onkyo).

#1 issue: Cable input-- Onkyo show's "no signal" (I swapped all the HDMI cables around.. no difference to any of the issues)

#2 issue: PS3 and Apple TV-- both play audio just fine, but there is no video at all. (Though my projector DOES display its own (momentary) screen it shows when a source comes on line to show where it's connected, so I assume SOMETHING is getting to the projector.

I tried both HDMI inputs on the projector, but never got video . Of course that doesn't explain the sudden "no signal" from the cable box...

I'm thinking this might be a problem with the HDMI (is it a board?) in the Onkyo. If that's the case, is it a costly fix-- am I better off starting new at this point?

Any help is more than appreciated!

As a test try connecting your peripherals to the projector to make sure they are working.

It does sound as if your HDMI board is down, unfortunately that is a costly fix.

After testing, the PS3 and the AppleTV play direct to projector with no problems.

The Comcast box still displays nothing at all.

So far, it looks like I may have 2 problems: a dead Comcast box and a receiver that won't dislay the HDMI video out. Geesh-- what are the odds both go south at once!

I'm wondering if the "dead" connection form the Comcast box is somehow preventing the Onkyo from displaying the signal it's getting from the other 2 devices? Will try that next (running normal set-up with Comcast disconnected)

If that doesn't work, would you say it's confirmed the Onkyo has defective HDMI out?

 

[Eddiwill]

OK, a test of the Comcast box on a different set shows the box indeed does NOT output any signal. So, with much more certainty, I would say the Comcast box is shot.

Even w/ the Comcast box out of the loop, my other devices still will not display when routed through the Onkyo, despite resetting, changing the inputs/cables etc.

I'm thinking that either the Onkyo or the Comcast box HDMI went belly up, impacting the other-- is that possible? If so, anyone have an idea as to which device caused the calamity?

Thanks for all the help here... what a huge mess!

If I had to guess, more likely you had electrical spike which could cause both issues to equipment connected to same circuit.

I think you are likely right. Power protection is the one important thing that members neglect.

Rules.

Uber ground. Cable, telephone etc. tied in with huge copper cable.

Whole house surge protection.

Smart UPS to everything that has micro processors.

Those are the rules for a happy AV life.

The manufacturers get a bum rap.

I'm pretty sure the vast majority of failures could be prevented with those rules.

I had everything running through a Tripp lite surge protector.

However, looking at it now, I see the green "Protected" light is not lit, but the red light beside "Ground" IS lit. I assume this is not a good thing...

Sorry, I know very little about electricity. Dees anyone know if the current lights reflect an event, or it's just showing that somehow the outlet is no longer grounded? Looking for the documentation, but can't recall where it is!

Thanks again.

OK. The manual says it's GOOD that the red light is on,meaning it's grounded. But of course, the green protected light indicates it's no longer protecting. I wonder if the "event" killed it or it ceased to function prior-- I am leaning heavily toward the former-- th elatter seems unlikely, to me-- though, like I said, I don't know much about all of this!

If the green is not lit that means that it is shot and no longer protected, you porbably got several hits and the first one killed the Tripplite, and the second one got your gear. If you have good insurance they may be able to cover the damage (each insurance comapny is different). Get a new one and sorry to say your board is shot. This weekend shoponkyo is having a 20% off refurbished reciever sale and they currently (as of 10 seconds ago) have a refurb 807 for 649.00 and at 20% off that's 129.80 off so 519.20 for a 807 (but better hurry this sale ends this weekend.

Those type of surge protectors are as much good a sick headache.

A good quality surge suppressor can go a long way toward protecting gear but they need to be changed out at least annually.

 

[Eddiwill]

Yeah, I see I definitely need go go bigger/better in tis regard. I have an electrician coming to check things out and to quote on a whole house solution. Are any of the affordable ones good?

Also, think I could get anything for the Onkyo? seems to work fine regarding audio-- just no video over hdmi.
