Marantz – The Real Issue

Crys_00100I think I’ve found the issue. EDID.

The EDID or Extended Display Identification Data is a packet of information sent from a monitor or TV to the source of the video and tells the source what types of video the display can process.

Imagine for a moment that we have a receiver from 2013 – pre 4K – that contains an HDMI switch. Now imagine that one buys almost any TV today – almost all of them support 4K. Now imagine that one purchases something that produces video – BluRay player, XBox Console, Playstation, even a modern set top box. Most of these support 4K video.

So what happens if the EDID from the 4K TV passes unchanged through the NR1504 from 2013 to the video source that can produce 4K? Well the source happily produces 4K video and the NR1504 cannot pass it. Black screen? Apparently.

Was the Marantz 1504 never modifying the EDID? Or did it just start not modifying the EDID? Or did the Linux computer get a new driver that was willing to produce 4K video?

I hooked up an HD monitor to the NR1504 and hooked the Linux box back up to the Media input and voila. Everything works fine, of course.

It seems clear that in this world of ubiquitous 4K sources and displays, the Marantz NR1504 needs to be modifying the EDID or producing one of it’s own to continue to work.

I’ve used the display settings in Linux to use HD only and that works fine with the TV, but when I plugged it back into the NR1504 it still didn’t work. Oh well. Time for a new Receiver that gets 4K. But at least I can use the Linux system by plugging it directly into the TV and setting it to HD.


Marantz – Watch Out for Updates!

Marantz NR1504

I’ve had a Marantz NR1504 for a couple of years at least. As you can see, it was released in 2013 and is no longer made – according to Marantz Tech Support.

My Marantz NR1504 Receiver recently took an update over the internet. Automatically. And the next time my Linux Mint System booted, the receiver refused to pass video from the Linux system. Dish Hopper and Sony Bluray player work fine. I thought the problem was the Linux Kernel Update that I’d done, so I pulled the machine out of the Entertainment system and attached another monitor to it thinking that I would need to re-install Linux Mint 18.2, but it came up fine with the other monitor. Also, I’ve swapped HDMI cable and used other Receiver input ports, and when the Linux system is attached directly to the Vizio Pseries TV, it works fine, in FREAKING 4K no less. Of course the NR1504 only supports HD, not 4K. In 4K the print is so small on my 65″ TV that I can barely see it. But it works fine and Youtube is also fine.

Linux Kernel Crash – Need to Back Out




I accepted a software update of the kernel on my LM 18.2 system, and now it won’t boot. Probably someone rushed out a SpecterMelt fix or something. Anyway, I need to back out these kernels later than 4.4.0-98 so they aren’t boot options. If I restart now I need to go through grub advanced options to get system started.

How do I back out these recent kernels?

Update: Use the Update Manager > View > Linux Kernels to choose which ones you want and you can back them out.

Update Update: Not a crash at all. Linux was fine. The Marantz NR1504 took an update that blacked the screen. Linux works fine to other monitors and the 4K TV without problems on the latest kernel.


Display Failed- or did it?

Battle chair

I got up this morning, and tried to wake up my computer like I always do, but it didn’t.

As you can see, I have what I call a “Battle Chair” which you can find here and here. I’ve upgraded the computer again since 2013, and the monitor is now an ASUS PQ258Q – 2K monitor.


Well this morning, the monitor would not wake up. I rebooted the computer a couple of times. No luck.

Windows 10 Anniversary Update a Mess

Boot Failure after Anniversary Update

I had my Alienware Area 51 since about 2007 – since right before DELL bought Alienware – and about a year ago I upgraded to Windows 10. No problem. Here are the specs.

But the Anniversary Update fails miserably on this machine. It keeps waking up dead, if you see what I mean. A couple of days ago it was running, right after the update but without the 2 additional SATA hard drives. The drives were obviously still in the system, but Windows 10 did not see them. And Disk Manager did not see them either. So I did a RESTART with the start menu and got into a world of hurt. The system never finished restarting. After 10 minutes it was still doing an animation on the screen saying Restarting. So I used the power button, it failed to boot, and then finally I got it back by going back to the previous restore point using essentially the same process you see below, but it looked different that time. No application windows just blue screen dialogs.

Now it’s happened again, but differently. Continue reading “Windows 10 Anniversary Update a Mess”

Linux Mint 17 – Auto Mount Solved

SOLVED – see below

The Disks
The Disks

I have a couple of hard drives. But I can’t get them to AutoMount. Used the post here to try to get it to work, but this does not work. The boot stops with a message to “Type S to skip mounting or M to Manually whatever”.

I set the options to LABEL= to match the old mount point, I hoped.

I can mount the drives manually using the little Arrow in the Disks program next to the partition.


According to this post under Ubuntu: You must uncheck the “Show In User Interface” option:

Correct Options

The drive[s] then show up as /mnt/YOURLABELHERE and rebooting remounts the drives properly.

But these are not the original mount points that were present when the disks were first added to the system. So I changed them and they still mount properly.

And they appear in the user interface, as you can see. Voila! Why is this so complicated?


BTW, this was published for 2014 so that it does not appear on my first page of the blog. There is no other way I know to get things off the first page.

Linux DVD writing screenshots

When I choose Disk Image Writer, on LM17, I get a window for which I have no understandable choices. So the question is how am I supposed to use this interface to write an ISO the DVD+R that I have just inserted.

Oh. I see:

Disk Image Writer is a backup program. Brasero is the ISO media writer program, among other things.

Thanks a heap,

SourceForge broken – only for one browser on one machine

Broken SourceForge
Broken SourceForge

SourceForge is broken and looks like this, but only for FireFox 32 and only on one of my four Win7 x64 machines. Works fine on MSIE 11, and Linux Mint 17, FFox 32 on VirtualBox on the same machine.

Many things do not fix this problem:

  • Clear the entire browser cache, history, and sourceforge only or all cookies.
  • Mess with various settings in Ghostery and block and unblock many of the trackers. With the same tracker block profile on other machines those work fine.
  • Remove any unnecessary plugins and extensions. LastPass, Ghostery and Flash are the only ones left on all the machines. No difference.
  • Uninstall and re-install FireFox.
  • Flush the DNS cache.
  • Reboot the system.

No joy after all of these attempts. Anybody got an idea to fix this?

Update: 11 Sept 2014 All fixed. Who knew. Maybe some mirror had a bad CSS file. Anyway. All better now. No clue why one of my systems was bad, and why clearing the cache and cookies didn’t fix it. Sigh… Summer lightning.
