Samsung TV
Denon AVR-E300 connected to Samsing TV HDMI3 input via HDMI
DirecTV Receiver connected to Denon Cbl/Stb input via HDMI

System was DirecTV connected directly to TV. System worked fine for weeks.

Today i added a Denon AVR-E300 to the mix with a 3' HDMI patch cable.

When i turn the TV & AVR on...sometimes...the lower half of the screen is pink with squiggly lines. See photo below.

If i turn the TV off and then back on this usually corrects it. If i change from HDMI3 to another input and then back to HDMI3 on the TV it usually corrects the issue.

I got this room wired/programmed and briefly tested on my way out of the door. In the room next to it i have a similar model tv and new denon avr that does not experience the issue.

I assume its an HDMI cable or an AVR issue but i didnt have time to swap & test etc. I can do that tomorrow. I have more Cables, AV Receivers, DirecTV receivers. I just wanted to post this tonight to see if anyone else has experienced it and maybe knows where i should start my troubleshooting.



Thanks.

looks like it is showing characteristics of top and bottom 3D.

Looks like it wants to show 4K material but isn't getting it. Is the TV, AVR and Cable box (if you have one) set to output one resolution, or are they all set to take anything and work with it? I like to set the res on the source so it can output the best possible, Cable or Sat box to 1080i/p and the TV to the highest res that will go to it. Less resolution management by every piece reduces problems, from my experience.

Good catch. Definitely seems like it could be related.



I haven't touched any settings for the AVR or TV yet. DirecTV receiver is currently set to output everything. I will uncheck the other /lower resolutions.

I had a similar issue with 2 Comcast-Motorola boxes thru a DM system. It had worked fine for 6 months, and the morning of the Superbowl, 2 of the TV's were doing something similar. Turned out to be the Motorola boxes. One of the TV's was only a 32 that did not have 3D capability.

I don't even want 3D. I wish i could rip out everything (software and hardware) from the TV except the ability to turn on and display video from 1 HDMI port.

I really wish someone would create a CI monitor series thats meant for distributed/matrix switch video systems. Slim plain paintable bezel. Form and software/codes never ever changes. The only thing that changes is they repalce LCD panel with new models every couple of years. Seriously whats the point of changing how the TV looks every year? You want to know what customers want to see around the edges? NOTHING. Make it slim and plain and be done with it.

So you want a projector? :-)

I've seen this on a few Denon Receiver's (usually connected to pioneer TV's, but occasionally samsungs too); if its like the instances I've dealt with, you've got a bad video processor/converter/scaler. you need to set everything to a fixed resolution 1080i usually works best. Additionally, you need to go into the cable box settings and set the 480 conversion to off or (native) stretch I believe.

Also if you've not already done so, do a microprocessor reset.

Man I HATE that this is always the common response when calling tech support. Are you f*#king kidding me? Why not build a product that doesn't require a microprocessor reset before you even start an install. WTF

It's the device that needs to be reset, not the product. None of the manufacturers make the microprocessors they use and the processor is susceptible to static. Probably costs a lot less to tell people to reset it than to use an anti-static bag and since resetting the processor usually prevents many problems, it's a workable solution. For them.

Dude, holding 2 buttons and turning the power on costs nothing and I've seen that resolve many problems over the years. Why wouldn't you do that when you first take it out of the box? Do you believe that the video settings on TVs out of the box are perfect too?

Seriously? so you are ok with a product that out of the box requires a Microprocessor Reset? that is the shittiest thing about denon and marantz, WHY is this even necessary? I do it out of habit but it SHOULDN'T be necessary. We shouldnt have to roll over and accept this BS from a mainstream manufacturer

You really are a special kind of guy, Carl!

Yeah, this setup shows the possible "fault" in "default"!

As I've said, the best results with HDMI are obtained after you hammer and bang the living crap out of it so that it does the least possible nifty things. The nifty things are where the problems lie.


While this might be necessary, mentioning it as an also instead of DO THIS FIRST makes you do all the adjustments twice!


...uh... sorry, but... uh, none of the devices I know of aren't products, so I don't see the meaning here.


I'd love to see bcf1963's comments on this!

As I understand it, anti-static bags are used around sensitive components to ensure that, when handling bare boards and loose components, all places on those components are at the same potential. No charged finger can zap it, because you are to touch the bag first, then carefully maintain contact such that static potential cannot develop between you and the device (okay, product). Another good way to avoid static on a microprocessor is to make the connections to the microprocessor and then wrap it inside a metal box. I've seen those: they're called chassis.

Besides, if a microprocessor is zapped by static, you can't reset it without a desoldering tool!

Discovered that if i turn the TV on first...then the AVR...my problem is gone.

I tried choosing a fixed resolution and then the microprocessor reset first. Nothing changed.

I reversed my programming fix and the problem occurs again.

After 20 off/on's my programming work around is rock solid.

Any reason to continue down the rabbit hole? Or would you call it good and move to the next area?
