HDMI BALUN Issue

post #1 of 9

Thread Starter 
I just had a new system installed and it all seems to work fine besides the connection from the projector to the receiver. Our only option was to use two cat5 cables attached to Niles baluns. My cable receiver seems to work with sound and 1080i content, but when I try to use the Samsung blu ray player, it will only put out sound and sometimes splash up the samsung intro screen. We created two patch cables that go from the niles box on the projector to about 7 feet to the existing cat5 cables that were in the sealing. The cable, with extension is no longer than 20 feet to the receiver. We also tried connecting a HDMI booster and that didn't seem to do anything. Any suggestions would be great.

Equipment:
Panasonic ae4000
Onkyo 508 receiver
Samsung 6800 blu ray

So other than no audio or video, it's all good!

You need to isolate the pieces to see what combination isn't working:

1) If you hook the BD player directly to the projector with an HDMI cable, does it work?

2) If you hook the BD player to the Niles balun (bypass the AV Receiver), does it work?

3) If you change the BD player's output resolution to 1080i, what happens?

4) If you swap the cat5 cables around, does anything change?

From you description it sounds like 1080i content from other sources is working. So this could be an issue at the higher-bandwidth 1080p, or an HDMI handshaking issue, or could be a flaky cable. Figuring out what works together will narrow down the possibilities...

Oh, and when you say you "had a system installed" - was that a professional installer/dealer?

Thanks Jeff,

1) Yes
2) No
3) Going to try this with the blu ray player, but he did hook up an older 480p dvd player and it didn't work.
4) going to try this
Yes - professionally installed, this is the only thing they are still working on. I was hoping that there would be some type of device to hook to the two ends to test the cable between the projector and the receiver.

Can you run different cat6 cables temporarily to test the baluns?

Otherwise they should just swap out the baluns for different baluns. They should take care of this for you. Otherwise sounds like a trunk-slammer who doesn't really know what they're doing... :/

Are you getting snow or a black screen when picture isnt working? Could be a copy protection problem. HDCP doesnt like distance. If your getting snow, it's probably a copy protection problem.

My guess it's the BD player and HDCP

Not getting any snow, just the projector blue screen with the ports in the upper right hand corner. This has to be a cabling issue between the two baluns. We connect the blu ray directly to the receiving Balun and it doesn't work, but when we connect the blu ray to the projector, it works just fine. Tried different connectors on the cat 5 extension they had to install between the baluns, but that didn't seem to help...just like the vid/aud amp.

The projector is only about 13 to 15 ft away from the components, crazy how it seems like it's a signal strength issue. 1080i cable box works, but no blu ray. Hooked up an old non-hd dvd player and that didn't work either...very weird!

One other question. Once they figure this out and the dvd is working, can you tell me how i can make sure it is running at 1080p?? samsung 6800 dvd, and panny 4000 projector.

Thanks again

BD discs are 1080p24 but YOU can set the BD to Output 1080p24, 1080p60 or 1080i60 - hook the player to the PJ so you can get an image and set it to 1080i60 (you know your other source works at 1080i60).

Onkyo AVR + HDMI Extender is often a tricky combination - try each Source on a direct connection to the HDMI Twisted Pair Transmitter to ensure you get comptibility between Source > Extender > PJ.

Power cycle all connected kit everey time you make a system change - a pain I know but its what you need to do with HDMI (HDCP and EDID).

Power on the BD (set to 1080i60) without a disc in the disc tray - if you see a splash screen and can view menu's you know the connecetion works, if things fall to bits once you insert a disc you know you have an HDCP problem.

If things work OK direct then introduce the AVR - once thats all working you can worry about 1080p24!!!

To do this requires physically unplugging the devices, or hitting a physical hard-power switch (not common) on devices. Simply turning the devices to "off" which is really standby, leaves all the HDMI ports active. Just FYI.

...I didn't see the suggestion to try swapping the existing transmit receive pair with a new set. You test the CAT5 cable and connections to make certain you don't have a problem there (make up a new set...run them across the floor if you have to) and plug them up and see if it works to eliminate the cable/connections as the problem.
