HELP desperately needed (Philips 8807 service menu)

Hi... I was messing with the service menu becuase my geometry was
off... then at one point all my chanels were gone.. oh well, I could
live with that, I would just have to install them again.. BUT... that
wasent all... The TV can no longer to split text TV and screen, and
when clicking the "view mode" botton I can only select 4:3 and squezed
(use to be able to choose automatic, 16:9, 16:9 sub., Widescreen,
Super Zoom ETC.) Also now I cant select rthe TV's Digital Natural
Motion anymore... only Digital scan on and off is an option (as
opposed to 100hz, DNM, DS, double lines)

I REALLY need help.. I have no clue what I have pressed.. so I hope
one of you has an idea, so I no longer have a 500$ TV but rather a
1200$ TV...!! please help

it seems like a new OS has been installed really... features I once
had arent accesible from the menu... hmm... please help me!
