No HDMI Signal: Xbox -> Pioneer AVR -> Epson 8350 Projo

[bobafart]

I just bought a new Epson 8350. I ceiling mounted it, connected my 30 foot HDMI cable from my receiver to the projector. When I turned it on it says "no HDMI 1 signal found".

I troubleshot the set up, all cables are snug, etc. The correct input are selected.

I then tried a different HDMI cable and connected my laptop followed by my Xbox to this 20 foot HDMI cable -- the projector showed the images brilliantly.

Could the 30 foot HDMI cable either be defective (it's a new cable I bought from monoprice.com) OR could the HDMI cable be too long to send a decent signal to the projector from the receiver?

The Components:
Projo: Epson 8350 (brand new)
Receiver: Pioneer VSX-921-k (brand new)
Xbox 360 Sli (bought it 1 year ago brand new)
old Samsung DVD player
test Acer laptop
test Acer 23" computer monitor (cheap, old crappy, has HDMI input)
30ft 24AWG CL2 Standard Speed w/ Ethernet HDMI Cable - Black (in drywall - from Monoprice)
20ft 24AWG CL2 Standard Speed w/ Ethernet HDMI Cable - Black (testing - from Monoprice)



---
The Desired Setup: Projo ceiling mounted at the back of the media room. Receiver, Xbox, other inputs at the front left of the room. I fished a 30 foot monoprice HDMI cable which is supposed to connect the receiver to the projector.


---
Problem:

When connecting the 30 foot HDMI cable to receiver and projector (using both the projector HDMI1 and HDMI2 ports) the respective errors: "Source: HDMI 1 No Signal" and "Source: HDMI2 No Signal" display from the projector.


---
Troubleshoot 1: Xbox and 2nd Monoprice HDMI cable (20 foot).
Direct Xbox and 20 foot monoprice HDMI connection to projector displays Xbox pictures using both Projector HDMI 1 and HDMI 2 ports.

Troubleshoot 2: crappy Acer laptop and 2nd Monoprice cable (20 foot)
Direct laptop and 20 foot monoprice HDMI connection to projector shows laptop desktop perfectly. Both projector HDMI 1 and 2 ports work with the laptop and 20 foot cable.

Conclusion: Projector isn't the problem.


---
Troubleshoot 3: connect buried behind drywall 30 foot monoprice HDMI cable to Xbox and crappy Acer 23" old computer monitor. Xbox displays on the computer monitor. This is a direct connection between the Xbox and the computer monitor using the 30 foot HDMI cable.


Conclusion: 30 ft monoprice hdmi cable isnt the problem


---

Troubleshoot 4: xbox to receiver to projo
xbox hdmi connected to pioneer receiver hdmi input - (you can hear the xbox UI sounds so it is connected correctly to the receiver) - a short hdmi cable from another store was used here
30 foot monoprice hdmi cable is connected from the pioneer receiver OUT port to either HDMI 1 or 2 ports on the projector: "No Signal" for either Source


Troubleshoot 5: xbox to receiver to computer monitor

xbox hdmi to pioneer receiver hdmi connection (definitely connected because can hear xbox UI sounds with controlling joystick)
30 foot hdmi cable from pioneer receiver hdmi OUT connected to HDMI in for computer monitor
Xbox images shows up on the computer monitor and works well

Conclusion: 30 ft monoprice hdmi cable isnt the problem

Troubleshoot 6: xbox to another receiver


connecting my Xbox to my receiver upstairs (Pioneer VSX 10-24) works well to a 55" Samsumg LCD Smart TV (brand new).



- I changed the Xbox resolution to 420, 720 and 1080i -- none of these show video on the projo
- I changed the auto detect video feature to off (disabled it) on the xbox -- no video on the projo
- I tried HDMI and component cables as well as composite -- no vide on the projo
- I tried a few different HDMI cables too
- all cables are snuggly inserted into respective ports
- the correct INPUTs are being used/selected


- connecting the Xbox directly to the projector via HDMI gives video (but no audio since the projo doesn't have speakers) -- all resolutions work with a direct Xbox to projo connection





so what is the problem??? It appears the problem Xbox-AVR communication - whether it is composite or HDMI connection.

can someone explain to me what is going on here? anyone have any ideas on what I should do? I have to use the 30 foot HDMI cable (20 feet isn't long enough).

appreciate it, thanks

Hi, and welcome to the forum!

Your troubleshooting procedure was impressive. It helps us narrow down what might be causing it. From what you wrote, here's my impression:

• Projector HDMI input works
• Xbox HDMI video output works
• HDMI video input assignment on the Pioneer 921 is correct
• HDMI output from the Pioneer 921 works (with the computer monitor)
• 30-foot HDMI cable works
• 30-foot HDMI cable works in combination with the 921 (with the computer monitor)

So, like you mentioned, it could be the combination of the 921's HDMI output power, projector's HDMI input, and the 30-foot length of cable that is causing the issue. It's happened before. However, let's try some settings first, and possibly one more connection, to see if that will clear it up.

• Try turning the Video Converter on the Pioneer to "Off" (see page 40 of your owner's manual) - this is based on a comment in the "Troubleshooting" section of the manual on page 48
• Try changing the output resolution from "Auto" to the appropriate value, which I think is "1080p" for your projector (also on page 40 of your owner's manual)

If those settings (or others that people here can think of changing) don't work, try moving the receiver closer to the projector (if that isn't too difficult) and using a shorter HDMI cable. If a shorter HDMI cable doesn't work, then it's got to be a setting somewhere, because the Pioneer shouldn't have any issue sending a signal over a ~10-foot cable.

Mayhaps something like this product is in order to try
For only $11.25 each when QTY 50+ purchased - HDMI® Active Equalizer Extender Repeater - Extend Up to 100FT | HDMI Extender

Good suggestion, but I'd say try that only after the things that I mentioned. Increasing the signal strength might not be the solution.

 

[bobafart]

thanks for the reply.. i will do all those things you suggest but I believe they already done them all....


as an aside since the HDMI spec is not proven for cables >25 feet...

is it better to have 2 x 15 feet HDMI cables connected in the middle with the repeater linked above or is it better to have a single 30 ft HDMI cable?

which gives better HDMI signal?

thanks

That I don't know. You're probably just asking out of curiousity, but in case you're asking about your situation - it sounds like that 30-foot cable is already run through the walls, so I'd try that repeater connected up to the 30-foot cable first. You'll need another short HDMI cable to connect the repeater to the receiver.

No XBOX 360 video signal from Pioneer VSX-921-k also

Hello, new member here. I came across this thread which describes a very similar issue to what I am having.

I bought a Pioneer VSX-921-k new. I have hooked up my Xbox 360 to my receiver with component cables (its an early gen Xbox and does not have HDMI out). I also have optical out from xbox to receiver for audio. There is an HDMI out cable from my receiver to my Sharp 42 in. 1080p Aquos TV.

There is no video but there is sound for Xbox. The HDMI cable has to be fine because my PS3works fine via HDMI out from receiver. Also can't be component input on receiver because I tested a Wii with component cables in both component inputs on the receiver and received picture just fine.

My current solution is hooking up the component video to my TV and leaving optical hooked up to receiver... which is an irritating solution for a brand new receiver.

I just thought I would let Boba know he's not alone.

Welcome to the forum, Yeshuah!

Check out page 14 of the owner's manual for the VSX-921. That explains the video converter function and may help you get it working. If that doesn't get you working, just let us know and we'll walk you through it.

Hi thanks for the quick reply. I turned the video converter off for that input but I,m still not getting picture. This is odd!

Hi. You need to have the video converter on because you want the Pioneer to convert component video to HDMI. After you turn the converter on, make sure that the component video input for your Xbox is the primary video source. That's mentioned on page 14.

 

[Yeshuah]

I tried with the converter off and on and I'm sure its on the right source and the Tv is set to the right input but no picture. I feel like an idiot cause I cant figure out the problem...usually figure it out eventually but not this time thanks for your help again.

 

[Yeshuah]

Update: not sure if you're familiar but the av out on older xbox cables has a stupid switch which changes between HD and standard (left, right audio and single composite video plug). It had naturally been set to HD using the component ends of the cable as opposed to the composite ends. Anyways I switched it to standard output kn the cables and the xbox restarted and picture appeared, albeit crappy up converted signal (it appears very grainy) at least I have something so far. Yeesh!

 

[Yeshuah]

Clarification: the component cables are still plugged in... I didn't actually change the cables, just flopped the switch from HDTV to standard

 

[Adam]

Thanks for the update! It sounds like it might be something that is mentioned in the Pioneer manual - that some video game resolutions can't be converted (which you probably saw because you tried turning off the video converter).

You could run component cables from the Pioneer to your TV, but that probably isn't going to be any more convenient than when you directly connected the Xbox to the TV.

You have done a good job of trouble shooting.

It still might be the cable. Digital signals are not like analog. They are sent in busts, and slight damage to cables can cause reflections and data loss. Now there always is data loss and there always is error correction at work, to restore and or interpolate lost data.

Now the problem is there is variability between equipment as to the strength, of not only error correction, but data buffers. So you could easily have some equipment work with highly incomplete corrupted data and not others. Also remember HDMI is a two way communication for the HDCP codes.

The next issue is that HDMI cables are very fragile, due to there being so many conductors in the cable. It is not a good idea to fish HDMI cables. HDMI cables should be gently passed through conduit.

Since you fished the cable, I'm putting my money on slight damage to the cable caused by fishing.

So you absolutely need to know that your Pioneer receiver can communicate with your projector with another cable.

If it can't then there is an HDCP code incompatibility between your receiver and the projector. This is possible, but unlikely. If it does communicate then the problem is the cable.

Now you can get HDMI cables that will go 50 ft.

If you do have to use a repeater, the best location will be at the midway point.
