I have a problem with my Minix

[Sam0703]

Me dieron un Minix pero cuando lo conecto a mi televisor no da imagen pero si prende la luz, no se si es porque le falta la antena, pero me dijeron que funcionaba sin ella, Alguien podría ayudarme.

Mod edit:
They gave me a Minix but when I connect it to my television it doesn't give a picture but if it turns on the light, I don't know if it's because the antenna is missing, but they told me that it worked without it, could someone help me.

Please look at the label on the underside of the device and tell us which device you have.

Better still post a photo of the underside of the device!

@Sam0703

Please take a picture of the model you received (as @Villa said).

Missing Antenna:
-You only need the antenna for better wifi signal

Some tests you can do:
-i see in the picture a blue light
-for now test the device with another TV/HDMI cable/another hdmi input
-check also the PSU specs and if you have another PSU change it. (It needs to be for the correct model, of course).
