I hope I'm posting this in the right place.

My questins is if there are hidden menus that aren't written in the technical manual of the TV exist. I dn't mean those menus I never use, I have enoughf experience to make a difference, but I mean the kind you have to press certain buttons or hold the longer to acces them. Or, my other question is if there is some way I could reset all my settings, tv channels, everithing, but not by remote or anything, If I could do something similar to the BIOS seset for a TV.

Now, If you're curious, this Is the way things happened:I was watching TV when I pushed some buttons on the remote and a menu I never encountered before popped up in the upper left corner of my TV screen. It had some wierd settings I never met before but I Don't remember them exactly, but you had to set some numbers, a frequency or something.

I was a little alarmed by this menu, so I tryed getting out. Shutting it down from the remote didn't work, so I managed changing ssome settings and exiting the menu somehow. Since then, no other TV programs except the one I was in when I screwed the settings work.

I'm shure I can't acces the meny any normal way, and no matter how wierd it sounds I think there are hidden settings. Please help.

Cheers.

PS: thanks for your pacience and excuse my bad grammar and limited knowledge of TV's.

When in doubt pull the plug out. You accessed the factory settings and set those to something else. A normal tech fixing this takes notes of numbers etc before attempting changes. That you have screwed it up, now it will take someone who knows the set well to fix it.
