One of my customers called me to say that when he streamed Netflix from his PS3, the picture had a green tint to it, but when he played a disc, the green tint wasn't there. He also has Directv, and there were no color problems there either.
However, the screensaver on the receiver was all green, as well as the setup menus, Pandora etc.

Here is the system: Yamaha A2030, PS3, Directv, Sharp projector (don't know the model number, sorry).

He has run updates etc to make sure that wasn't a problem.

When I go by, it's like he said. The menu on the PS3 is green, the Pandora screen etc on the receiver is green, but Directv is normal, playing a BluRay disc is normal.

I call tech support, and the tech is as baffled as I am, he's never heard of an issue like this. He suggests I use HDMI 2 on the projector instead of HDMI 1. What can it hurt, though I can't believe it would make a difference.

Sure enough, that put everything back to normal. PS3 looked great, Netflix fine, Pandora fine, no green anywhere.

I get that an HDMI port could go bad, but selectively like that? Netflix is green, but your DVD is fine? Satellite is fine. But the screen saver on the AVR is green?

Live and learn, but does anyone have any idea how something like that could have happened? I mean, all's well that ends well, but I want to know why, dang it!

Brent has talked about this before.
And no, not all HDMI inputs are equal. Some go thru extra circuits in the video display (ARC, CEC, MHL, etc...) that can cause problems on just that input and not the other HDMI inputs.

ALL installs using a receiver use HDMI2 on the video display. I learned this in some training years ago.

But that is incorrect.
On a lot of models, the HDMI2 is indeed the one you want to use. But not all models from all brands are like that. For a few, it's HDMI1. And seems I remember an HDMI3 being the best choice on another.
I don't have my notes handy. But the point is HDMI2 is NOT always the best choice.

Are the color space settings on all devices set the same? I've seen green tint on a YPbPr signal going into a RGB input.

Set everything to YPbPr.

That's a bit extreme. This kind of short would show up on the simplest tester that tests all four pairs.


Okay, and maybe I will, too, but I think his reasoning is wrong. Just as a satellite installer will avoid splices in RG6 for incorrect reasons but with great results, this guy is getting great results but I don't think his reasoning is correct.


Again with the shorting idea! Any short that will burn up a device will be pretty low resistance, and the tester will find it before you connect any power.


What resistance? Looking for zero resistance, or infinite resistance, or, say, a hundred ohms; those are all looking of resistance. No connection at all is infinite resistance, meaning there's no short. No resistance at all means a short, so of course that's no good. And how would there be anything between an open (infinite resistance) and a short? Some hundred ohm resistor just falls into the connector somehow?


This totally begs a clear answer to my questions.


Is this also the case with the EZ45 connectors?

Um what? Did you reply to the wrong thread there sir? I know the word "weird" is in the thread's subject line, but this is weird in itself.

The only thing that I could think of why only a selected showed the green tint but the other's did not. Is that the ones that showed it has a max video process of 1080i. Where as the one's that worked great, have the ability to output 1080p. Now why did the 1080i produce a green tint... you got me.

KOT

I don't do a lot of front projection, but never heard that certain inputs should be used. Where do you find that info? In the user manual? On the manufacturers website?

The issue though, is not that the green tint showed up on a source, but that the tint was intermittent on that source. For example, the PS3 displayed normally when playing a disk, but had a green tint on the menu and when you streamed Netflix etc.

The green tint didn't show up on Directv, but it did show up on the receivers screen saver.

This was the strangest part.

Typically ARC is on hdmi 2. Other than that, I don't know.

KOT

No, here. KOT tells why in the last post.


Since the screen saver is of a different resolution than HD programming, and Netflix might easily be set to a resolution different from that given when playing back a disc, I'd look to resolution for the answer, or, more specifically, the display's inability to handle one or more resolutions.

The DirecTV receiver can help you out here. Set it to output all resolutions, then use the Format button to cycle through them. Maybe you'll find one or two that always output that green problem. I've seen a plasma that could not handle all sources without messing up the picture, and it was solely a flaw that made the display unable to show higher resolution images. There's no reason there couldn't be a flaw that would make it unable to show lower resolution images.

KOT, no, I looked at my answers that you wondered about, and each one was to the issue I quoted. For instance, if a POE supply turns on because it sees a resistance at the other end due to a wiring problem, then the simplest CAT tester should have shown a short on the cable. How is that not related to the issues?

I guess the part I left out was that this set-up ran for 18 months before the green tint showed up. On projector input HDMI 1. Switching to HDMI input 2 "fixed" it, though I have no idea why. That is all that changed. Didn't change the output of the PS3, didn't mess with any settings at all. Just moved the HDMI cable at the projector from 1 to 2.

Like I said, weird. But live and learn.

And I'll apologize now for leaving that out Ernie. A glaring omission.

Lowhz has probable culprit. you need to check the default color space settings. Generally the projector will have a choice of Computer or Video/RGB/I don't remember off hand. The follow up to this is it could easily be a bad sync issue where the source and display are having issues communicating the proper color space.

The Sync issue could possibly have been caused by static electicity build up in the cable as well...and disconnecting from the projector discharged it (had this on a half dozen systems in the last year or so), since HDMI2 seems to be working, congrats...but if you want to determine if this was the cause the next time you're out there try HDMI 1 again.

Good luck.

Your first post was on July 18. This is from the 23rd. When did you "fix it"?


You mean you fixed it and forgot to come tell us? I can see that happening. No big deal.


How would the color space settings allow a DirecTV receiver's TV channels to display properly, but mess up the graphics that originate in the receiver? That's menu, guide, etc. Ditto the PS3 or whatever -- the same device sometimes had this problem and sometimes did not. I thought color space was a universal setting.

Short answers/reasoning...I'm sure there's more technical information out there (and additional reasons)...but this is what I know from personal experience.

Option 1 is that each type of content can be a different native file format with its own color space and if that information is not decoded (or processed) properly it can lead to the following circumstances.

Option 2 a firmware update (or loss of power) some where screwed something up (ie reset the display to computer sensing via Sync mode versus video mode)

Option 3 static electricity build up on the cable causing sync to be faulty

Option 4 as stated by someone else, video processor issues related to resolution (or also possibly reset due to a firmware update or loss of power)
