No signal to tv when startup - NUC6CAYH

DGreen77 Oct 12, 2017 9:13 AM

Hello all,

i have had this nuc for about 10 weeks. From the start i have had an issue with the signal to my tv.

My old nuc (from 2012) worked greate with my tv, a LG65uh664v. But my new nuc dosent give a signal out and the tv goes

to screensaver saying no video input. This happens all the times and i need to restart the nuc 5-6 times then it suddenly works.

i have disable hdmi-cec in bios, updateted to latest bios...

i have no more ides. Anyone seen this before?

You can avoid this some of the time by disabling Monitor Sleep in Windows. If you also disable System Sleep, you will never see this occur (though you will be running all the time (albeit as a low power level) as a result).

It is connected with HDMI cable.
I have tried 2 diffrent cables. Same problem with my new NUC, both cables works with my old NUC.

I will try to make a report tonight after work.

Oh, you'll still be able to power off; you just won't be able to do so via Sleep.

Thanks Daniel.

Please try running the Download HDMI 2.0 Firmware Update Tool for Intel® NUC Kit NUC7i3BN, NUC7i5BN, NUC7i7BN, NUC6CAY. One more thing, please make sure your HDMI cables are category 2, this since category 1 cables only handle 4K @ 30 Hz.

Amy C.

Hello,
I have tried the HDMI 2.0 Firmware update before. Didn't help. Also both my HDMI cables are cat 2 cables. They are both working perfect with my 4K sat box.
Last night i had to force to power down (hold the power button for 4 sec) and retry to start 6 times before i got a signal to my tv.

Thanks for your answer.
I don't really follow.. Can I power off, because that is what i do today i think? I shut down from windows 10 and the NUC turn off.
Problem is to get a signal to tv when power on again..

Daniel, thank you for your patience.

I was reviewing this matter and noticed that your Windows® 10 build version is 15063. Just for testing purposes, is there any chance to test a different one?

Hello,

Sorry don't have any more hdd to test on. But i did try a usb with mint Linux on. This usb boot perfectly on my laptop, but not on the nuc.
Same problem, no HDMI output. But i don't think it software related, cos the POST or bios dont show up.
Strange thing is that TV notice that the NUC was turned on since it ask if i whant to change input to HDMI3 (or HDMI 2, i tried both). This happens all the times but one out of 5 i get Picture.

Daniel, thank you for trying the suggestions.

The test you have done with Linux Mint now indicates us that this could be hardware related. The port on the Intel® NUC might be damage, so in order to rule our this possibility replace the unit. Please, get in contact us directly in order to check your warranty options, find our contact options here: Contact Support. Let the agent know that we had this conversation.

Let me know how it goes.

Regards,
Amy C.
