My PC has got no video signal on its 3 ports: DP1, DP2, HDMI. I tried an adapter USB/HDMI, too: no success. Any solution? https://www.amazon.it/photos/share/wlvL8PYndRoxujzv7WFD5UP710DOL7F2Ln68HQgMMMl

I was unable to determine a "match" to some of the connector layout on the left of the picture. DC IN1 appears to be a barrel power connector. PWR4P1 appears to be an ATX 12V 2x2 connector. The FP1 front panel connector is not hooked up. Check for cable assemblies trapped in there somewhere. Also, check box contents for "sub-assemblies" yet to be put into place. The wall adapter could be a 12VDC unit. I suspect there is a powering problem of some sort. Does it have a fan ? Does the fan spin ? Paul

I cannot find a user manual or hardware manual on the site.
This is one of the first "must have" items before purchase.
If a manufacturer offers no PDF, I do not buy.

I would verify the 12V @ 5A adapter is working correctly first.
With the cover off the box, as you have done, take your multimeter
to the 2x2 ATX 12V, as you can monitor whether 12V power is present,
using the pins within the 2x2 connector (while the adapter is
connected to the barrel power input).

Power Adapter 12V Power Input, supply 12V 5A power adapter within the package
Auto Power On Support Auto Power On Function
So the missing connection to the FP connector does not matter,
as it powers up when +12V @ 5A is present. The "SW" appears to be
a "blank" or hole-filler.
There would seem to be no thermal tape for the unit. Heat travels through
the air inside the casing, to the Aluminum chassis fins.
The monitor output should be on the HDMI connector. Connect a 1920x1080
monitor with HDMI input to that connector, apply power to the unit, and
see if you can enter the BIOS.
