No acess to bios on tv, sometimes no image at all

[Vorphalack]

Hi.
This wil be long, and with my poor English, I will ask for some patience.
The hardware in question is...
asrock h110m.itx (updated)
Ram 4gb crucial (tested in another pc... ok)
intel celeron g3900 with graphics hd510
tv LCD samsung
AV amplifier yamaha rx-v367

So I bought that mobo, ram and cpu, new to build an HTPC media center
conected to my desktop monitor the media center works fine.
Connected to my AV amplifier, I press f2 or DEL and no image at all, so... no acess to bios.
If I let it go to SO works fine, load SO, can run kodi, have a great sound and image.
Conected straight to TV 100%.
so... my amplifier make some delay and\or imcompatibility.
How can I solve this (if it is possible)?
thank you very much.
Rui
