Intel NUC7PJYH2: HDMI Firmware Bug

[LeCaNo]

Hey there,

i have a Intel NUC7PJYH2 since a year and i have the problem that i have no picture when i start the NUC and the TV will be turn on from the NUC. If the TV on and i start the NUC then the problem not exists.

On some blog comments and on Reddit some users say thats a HDMI Firmware Update was needed but the HDMI Firmware Update doesn't come for die NUC7PJYH only NUCs with Intel-Core-i get this update like e.g. NUC8i5BEH or NUC10i5FNH. I don't know if it's true but it seems legit. I also doesn't knew if i can as a new user can post some links.

The problem is known by Intel. I hope that a HDMI Firmware Update comes someday.

If these informations are needed:

• Latest BIOS
• Problem exists under Windows (20H1 and 20H2) and Linux (Ubuntu 20.04 and Arch Linux)
• Testes with the following TVs
  • Xiaomi Mi TV 4S 43"
  • Telefunken 40" (don't know the exact model)
  • Samsung 65" (don't know the exact model)

I find it a pity that this problem is known for a long time but is not fixed by Intel

First of all, there is nothing about your two problems that I think point to there being a LSPcon F/W bug. Based on my experience, there is a higher probability of there being BIOS bugs that are responsible for these issues rather than there being LSPcon IC F/W bugs. LSPcon IC bugs are problems like screens flashing or flickering or something like that.

Secondly, the fact that there is a LSPcon F/W update for some other NUC doesn't mean that there are any for the LSPcon IC used on this NUC. They could be totally different ICs. Even in cases where it is the same IC, because NUC release dates vary, a LSPcon IC F/W update might have had to be released for one NUC but this updated F/W update shipped installed in other NUC models.

I have to say, I am not happy seeing people putting in Subject strings like this where it hasn't even been proven to be the case. The problem with this is that one person's speculation can become another person's fact.

Thanks for your answer.

I would like to apologize herewith. When I wrote this post I was very frustrated because this problem has been bugging me since I got the NUC.

I have therefore not considered a BIOS bug, since this problem would be probably already been fixed.

A shortened, translated comment from the review on elefacts.de

"Apparently the firmware (not BIOS!) of the HDMI chip has a quirk. I almost always have to turn off my TV after booting and turn on again otherwise I have no picture.

[…]

Intel sells totally bugged boxes, hope something will happen. For the expensive i models there is a HDMI firmware fix exactly for this problem, unfortunately not for the cheap J5005 models. In the Intel support forum the Intelmods don't really help either, they annoy with pointless questions and suggestions. Although they themselves know that it is a firmware bug with the HDMI problem, the net is full of them."

Turn the TV off after booting and turn on again doesn't help always. probably the comment is very general and was applied to the NUC7PJYH.

Hello LeCaNo,

Thanks for your response with some resolutions from your end.

I want to start by saying that this specific NUC model does not have an HDMI firmware version to download since this unit doesn't need it, reason why there are no available versions on the downloadcenter.intel.com

• Recommendations from our will be to first perform a BIOS Recovery https://www.intel.com/content/www/us/en/support/articles/000005636/intel-nuc.html
• BIOS version: JY0058.bio https://downloadcenter.intel.com/download/30156/BIOS-Update-JYGLKCPX-

• Test with other HDMI 2.0a cables.

• If the issue persists could be related to a hardware-related port issue. In that case I suggest you to contact us directly to assist you with the warranty through chat, phone or web portal below you will find the number and work days/time. You can use this thread link as a reference.

You just told him to update his BIOS to the newest version which is 58 and he runs Linux. You just told him to brick his device. Check the other thread! Intel needs to get this BIOS update fixed immediately!
