Need help install DVD player sunseeker mbs

[Bigfoot11]

I just purchased a 2020 MBS sunseeker I wanted to put a DVD player To watch when hooked up to shore power. The is a Connexx media enter in it and next to that is a empty shelf with a 110 outlet a coax and hdmi plug ins . I took my Blu-ray from the house and hooked up the to the hdmi and plug it it in. It came on but no picture to the tv I played with the inputs but no luck. Suggestions any thoughts on hooking up a 110 dvd thanks

check that the HDMI is actually connected to the TV or run a separate HDMI to one of the TV inputs.
