Question for Pioneer 5080 owners...

by HHaller2 / February 27, 2008 12:38 AM PST

Has anyone experienced any strange behavior on your sets when switching between HD channels and SD (and vice versa). I just noticed that when I switch channels there is bad image distortion...horizontal line across the screen and a broken picture (or several) displaced into the corners of the screen.

I'm using hdmi attached to a fios box...

any ideas?

This is what you do....

I own a 5080 also and I use DirecTV so the names of the settings I'm going to give you might be different from what your FIOS system uses, but I think you'll be able to figure it out.

With DirecTV there are two different settings for the resolution output of the box. The first setting is "Native", which means that the box outputs the same resolution as the channel that you're watching, 480i, 720p, or 1080i. When the box does this your TV has to do the switching between the different resolutions every time you change the channel. That is the distortion that you are seeing when you change the channel between HD and SD channels. If you notice in the upper right hand corner you will see the different resolutions displayed.
The advantage to using this setting is that I have found that the 5080 does a better job of displaying the SD channels at this setting than the DirecTV box.
The disadvantage is what you wrote about, which is when you change channels between HD and SD you get that distortion for a few seconds while the TV is reformatting itself. It will also do this if the HD channels are say 720p switching to 1080i. Not all HD channels are 1080i. Some are broadcast in 720p, such as FOX network, and other "cable" HD Channels.

The other setting on the DirecTV box is to turn the Native setting off. What that does is it makes the box output everything in 1080i resolution and at whatever picture setting that you set. This is the setting that the DirecTV installers always set the box to. At this setting your TV doesn't have to do any internal switching so you don't get the distortion when you are changing channels.

What you might want to do to use this setting is go to your setup menu on your box, then go to the HD settings, and see what your setting is set at. It probably will say "Native" or something like that. There should be a way to turn that off. That should take care of your problem.
I hope this helped, please let me know if this worked.

Thanks for the info. It seems that with Fios there is no "Native" option, and I have it set to 1080i right now.

After doing some homework, it looks like this is a "HDMI handshake" issue that has become common amongst Pioneer owners. The issue happens with component as well, but to a lesser degree. But only when switching from an HD channel to SD, and vice versa.

I'm still researching it but at this point it looks like one of those quirks that Kuro owners have to live with. I plan on speaking with Pioneer about it today, I'll keep you posted.

KC,
I got a tip over at AVS Forum...I rebooted the Fios box and set the 4:3 override to "stretch". Apparently it was the box after all.

Glad you got it worked out....

Do you experience any judder watching HD broadcasts or HD movies (BD or HD DVD)?

I'm trying to figure out why this happens with everything...with the handshake issue out of the way I just started noticing how much this occurs with my set. It happens in every setting of PureCinema (including off) and even when the orbiter is turned off.

It's definitely not a source issue, never happened with my old plasma or LCD.

No I haven't....

In reply to: KC,

Sorry it took so long to get back, no I don't have any judder problems with any source. I'm not sure what might be causing it, I recommend that you call the Pioneer customer service line and hopefully they can fix the problem for you.

One thing that you might try before you call them, is to unplug the TV for about 15 seconds then try it again. I had a problem with my TV once and when I called the repairman he recommended that, and it fixed the problem. What happens sometimes is that static can build up in the electronics and they can't discharge it until the TV is unplugged. I don't think this will solve your problem, but I didn't think it would solve my problem either.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
