Hi guys, I have a new NUC6CAYH which has no video output. I have tried VGA and HDMI connections, but the screen remains blank / black.

I have attempted the BIOS recovery, but I'm not sure that it's actually doing anything. Should I see some feedback from the LED whilst the recovery is in in progress? No POST or any output at all to the monitor.

1. Are you connected to TV or to PC monitor? If it is TV, try with PC monitor or other TV.
2. What is the P/N of the RAM you have installed?

Hi Leon

I've tried two different monitors, one with HDMI, and one with VGA. Neither is a TV.

I've installed 2x 4GB DDR3-1600 PC3-12800 204-Pin SO-DIMM and tried it in different configurations and slots. Without RAM, I get the flashing power light code.

Hi @DFish11​ ,

1. You did not provided the P/N of your RAM (you provide only the type). The memory may be incompatible.
2. Here you may check of the memory checked and validated by Intel for your NUC: http://compatibleproducts.intel.com/ProductDetails?activeModule=Intel%C2%AE%20NUC#0 and http://cmtlabs.com/2012/memCertPartSearchResultsAll.asp?bNav=True&sManuf=Intel&outside=False&sMN=NUC6CAYS%2FNUC6CAYH&oSubmit=Search
3. Your NUC supports only modules with 4Gbit or 8Gbot technology (i.e for 4GB module, if the SODIMM is double sided - will have 8 SDRAM chips. While for single sided module only 4 SDRAM devices)

Hi Leon, Just to let you know that you were correct - it was the RAM incompatibility causing the issue.

Installing Crucial CT51264BF160BJ resolved the issue.

Many thanks for your input.

[LeonWaksman]

Thank you for informing me. I'm gald that your NUC works now.

Regards

Thanks for this, I will check later. However, I'd still expect some video output when booting - or am I mistaken?

[LeonWaksman]

1. The Bios/SPI is copied to RAM. Without RAM (used also as a video memory), you can't expect any video output.
2. I would suggest also to check if there is video output with minimum hardware configuration: only with one SODIMM installed and without storage drive (i.e. remove the SSD and HDD). Some time, as result failed drive, the boot process hangs.

That all sounds logical, and thanks for putting me right with regards to (1). I've already tried (2), so I'll ensure RAM compatibility before anything else.
