TV HDMI Help

[GopherM]

About a month ago Mitsubishi replaced my large screen with a new and up graded model due to a minor problem with the original TV. On the old TV my DVD player, AVR, and DirecTV receiver all connected with no problem. I have not played any DVDs on the new set until this weekend when I bought a new Blu-ray. It doesn't work. I got the old Toshiba that worked on the old set and it won't work. The TV identifies that a new device is connected and on the new Blu-ray the Samsung intro screen comes up and then disappears. I can connect with the composite cables with no problem. Same with the AVR.

Anybody got any idea what gives? (I have tried 4 different hdmi cables and every hdmi input on the TV with the same results. :shrug:

Stupid question:
Is there another HDMI input on the TV?

Ywp. There are 4 hdmi ports and I tried each of them with every device that is not connecting. I have 4 hdmi cables and I tried each of them in each of the ports with each of the devices. Busy troubleshooting day.

Okay, lets clarify this.

TV
Dish
Blu-Ray
AVR?

All sources hooked directly to the TV? Separate receiver? All works except the BluRay? TV maybe cannot display 1080P? Os is set not to? A model number for the Blu-Ray and the TV would help.

That's a really old blog, but I'll see if there are any updates for my set. When I was able to connect the Blu-ray with the composite cable, I did make sure I updated the firmware on it. The TV is WiFi capable, but there is no option to perform an online update and I haven't found any references in the Mitsubishi support tab at their site.

Thanks for the feedback.

TV = Mitubushi LN-46164
Blu-ray = Samsung BD-C6500 (with software upgrade)
DVD = Older Toshiba DVD Player/Recorder
AVR = 1 year old 865 (not at home so I can't confirm).

During the TV setup I selected the auto detect for 720/1080P inputs.

I even went into the Blu-ray and tried down selecting the quality in steps all the way down to 480 and still could not get a handshake beyond the Samsung welcome screen.

I would try my BluRay on another HDMI set (neighbor?), and see if a different BluRay works on your set. Narrow it down to the bluRay or TV, or an incompatibility between those two specific models.

That was my thought also...but it doesn't explain why the Toshiba DVD worked on the old set but does not work on the new one.

I think the first move is to call Mitsubishi when I get home and see if they have any known issues. I may take the Blu-ray to a neighbors and hook it up to see what it does.

Were the DVD, Blu-ray and AVR playing when you selected auto detect?

When I saw this the first thing that popped in my head was authentication. Check this out...

HowStuffWorks "HDMI Signals"

HDMI also has the ability to protect data from piracy. It uses high-bandwidth digital copy protection (HDCP) to accomplish this. HDCP is an authentication protocol. Basically, each home-theater device has identification data and encryption data stored on its extended display identification data (EDID) chip. The source device, such as a Blu-ray player, checks the authentication key of the receiving device, such as an HDTV. If both keys check out, the sending device moves on to the next step. It generates a new key and shares it with the receiving device. In other words, it creates a shared secret. Ideally, this whole process, known as a handshake, takes place almost instantaneously.

HDMI Handshake Problems
One common problem people experience with HDMI is handshake failure. Sometimes, this is because the HDTV is an older, DVI-based model without HDCP support. But in other cases, there's an easy fix -- unplug your components and power cycle your system. This may reset the authentication cycle and restore your connection.

I'm sure you've done the above so you may want to call the manufacturer to see how you can reset the authentication.

Thanks. That's great info. I have not powered down the devices but have not unplugged them yet all yet. I did unplug the Blu-ray so I could plug in the older Toshiba and experienced the exact problem with it as with the blu-ray. I can also connect my laptop to the HDTV via hdmi and it works also. I'll try unplugging everything and see if that forces a reset and give it another try. Like I said, it does look like the handshake starts btwn the HDTV and the blu-ray when I get the intro screen, but it stops before the menu comes up.

Everyone is giving me good ideas. Thanks to all.

Aps...I really don't know. I haven't played the DVD since I got the new HDTV and it was piped through the AVR. I don't know if the AVR was recognized since I never brought up the AVR menu to change any setups on the AVR or funnel the DVD through to the new HDTV. I just know that everything was working with the old set but not with the new.

The more I think about it the more the info that PsyOps passed on makes sense. The DirecTV and my laptop probably don't require the encrypting that the other devices do, so they pass through with no problem.

Back from the holiday and I performed the steps from the last link that I posted and it worked like a champ. PsyOps, you certainly pointed me in the right direction.

If anyone else has a similar problem, you can't just power off the devices (all of them), you have to UNPLUG them to completely remove all the power and then wait several minutes. I just connected one thing at a time and powered down the TV before connecting the HDMI cable for the next device, then plug in the device, turn the TV back on and finally power up the device. The article strongly recommends that you not "hot plug" a device, i.e. connect the HDMI cable while the device is powered up.

Thanks again to all for your suggestions.

Glad to hear you got everything working together.

The On/Off switch doesn't sut off the power on newer electronics. If it's got a remote, you have to unplug it to "power down" and it's ALWAYS a good idea to "power down" when interconnecting any electronics. It's to easy to touch a wire/connector to the wrong plug and pop a circuit.
