I have a big problem ... after entering the secret menu I accidentally changed the type of TV
once turned off the TV you are no longer turned on ... I opened the TV and unplug the board BN41-01807a the TV turns on but obviously can not see anything
doing some tests I found that leaving just connected the cable on the tv card works perfectly but are forced to use my smartphone to control the TV since its internal infrared does not work

think that I could fix with a reset eprom?

sorry for my english ... I used GoogleTranslate

grazie

Can't you still access to service menu and revert to previous values?
If not, EEPROM reset will probably help you, check wiki for how-to.
If you need original values, you can check this screenshot from a similar model:

thanks for your reply
unfortunately I do not recognize the remote control, then I do not know how to enter in the service menu
I performed a soft reset and now I can not even control it with smartphone
