Blu Ray LG HR-550S - not showing any picture (pls help)

Gents,

I have a problem with my LG HR-550S BD player - when I try to start it it shows the LG logo and then the TV reports no signal - I tested with multiple TV / and HDMI cables (so I presume the only problem can be the player).

Can be any special settings or something ? I need to mention that I moved - and I changed the original TV (Samsung / but I cannot remember the model) currently I used a Philips (old model LCD tv) / Sony - 3d monitor / and a Samsung Monitor - with HDMI cables.

Can the factory defaults settings can be rested in blind ?

Thanks in advance for any help - I will also try to get in touch with LG service - but I wanted your advice first.

regards.
