Harman Kardon not working with 32" tv

[kayakingjeff]

I just bought a Harman kardon receiver and I am getting a flash when I play my blu ray. I am running hdmi to the reciever and one from receiver to my 32" LCD tv. Even on the menu screen it flashes every 2 seconds, but it doesn't when I plug the blu ray directly into the tv. It also doesn't happen when I plug the reciever into my 42" lcd. I have tried different hdmi cables and a second blu ray with the same results. Anybody have a fix for this problem?
Thanks, Jeff

What receiver do you have, and is the 32" 1080p?

 

[kayakingjeff]

I have the avr 1510 and my tv says it is in 1080p, but I know the resolution is less than my 42". I think this might be the problem, but I can't figure out why my laptop works with no problems. It is connected with the same hdmi.

 

[Muadib]

Did you try using a different HDMI input on the 32" tv?

 

[kayakingjeff]

Yes, different ports on the tv and the reciever.

 

[Muadib]

Are both TV sets 1080p

 

[kayakingjeff]

Yes

 

[Raduque]

Probably a handshaking issue between the AVR and the TV, or the AVR and the BRD player. Have you tried other sources, or a different BRD player?

 

[Muadib]

I agree with Raduque. If you don't have a different Blu-ray player, try setting the one you have to output at 720p, and see if the flashes stop.

 

[kayakingjeff]

I did try a second blue ray with the same results and I have tried changing all of the settings, including changing 1080p to 1080i and to 720. Flashes every time! I can't imagine that a good receiver won't work on a 32" tv!

 

[Muadib]

Did you go lower with the btu - ray player, and try a DVD in it?

 

[kayakingjeff]

No because it flashes even when the menu screen is displayed and no disc in the player

 

[Muadib]

Then I'm going back to the HDMI cables, although it could just be your 32". What make & what is the model number of the tv, and where did you get the cables?

 

[Raduque]

Maudib, I doubt it's the HDMI cables, unless it's physically damaged or he's using a >50m cable.

Try something other than a BRD player. Xbox, PS3 or even a computer with HDMI out. Perhaps you simply got a defective AVR, it happens.

Sounds to me like the 32" LCD isn't a 1080p. Not very many 32" LCDs are 1080p BTW. If 1080p works on the 42" in the same configuration, then it seems likely the 32" is 720p. You won't get a 1080p source on a 720p HDTV.

Post the TV brand and model number and we can clear this up.

And chances are the laptop isn't sending a 1080p signal to the 32" or 42" TV, either.

 

[Muadib]

Snake, he gets the flashing in 720p too .

 

[kayakingjeff]

The tv is an Electron LCD 3215E and has a resolution of 1366 x 768. The tv has settings for putting it into 1080p and i and 720. I get the fash regardless?!

 

[Muadib]

Do you get the flash if you change the sound on your receiver to just plain 2 channel stereo? Your tv specs say it came out before the Blu-ray spec was finalize, so it looks like the tv & receiver aren't getting the handshake right. Do you get flashes if you hook up a xbox or playstation?

 

[LoveMachine]

Describe "flash". As in the image goes solid white for a tenth of a second, or is an alternating normal then gray appearance? I had HDCP (copyright protection) issues with an old HDTV and bluray player. The TV sounds like a lower end model. Sometimes the off brand units don't bother to pay for the licensing to ensure proper compatibility with all sources. You might be screwed.

 

[LoveMachine]

Do the receiver and TV have component video connections? (The old timey RCA-like connectors - Red/Green/Blue) That plus an optical audio cable would get you 720p and 5.1 sound. Not the highest end signal, but still quite functional. That avoids HDMI handshake and HDCP issues.

As I thought. You will not get proper 1080p out of that 32" TV with that resolution. And 1366 x 768 is not 720p, either. Somehow the HDMI combos are not working, and it may also be because the 32" TV is not properly HDCP compatible is my next best guess. And your laptop video card is somehow bypassing the HDCP copy protection at 1366x768 on the TV because it's an older video card most likely without it.

720p - The Resolution is 1280x720 pixels, sent at 60 complete frames per second.

1080p - The Resolution is 1920x1080 pixels, sent at 60 complete frames per second.

Because his 32" TV resolution is not 720p, either.

Wow, you guys have been very helpful and informative in helping me understand why they are not working together! So thanks! I kept thinking that there has to be a setting that I am missing, but I believe you are right in that the tv is junk! I am going to run hdmi directly to the tv from blu ray and buy an audio coaxial cable to connect to my receiver. I should get 5.1 audio with that cable, right?

If it's an optical or coaxial sound cable, then yes. Some players (but not many) may have separate 5.1 RCA style jacks for each channel and if the receiver has separate 5.1 inputs, you can do that too. But your receiver only has one coaxial and optical audio connector. And usually the players only offer one or 2 of the 3 types, too. So check the player before buying the sound cable.

And since the HDCP receiver is the one routing and mixing the HDMI video and audio signals and then out putting them to the TV and speakers, the HDMI HDCP protection is stopping the HDMI signals at the receiver since the TV is not HDCP compatible.

And the reason the Blu-ray player can pass the HDMI HDCP video signals to the non HDCP TV without the interference, is because for HDCP to properly work, there has to be a handshake between 2 or more HDCP devices involved.
