just after turning on the television, press 3-1-9-7-5-3 and after that the "Mute" button. u have to do this steady but quickly. it will bring up the installation menu. there you can find auto tuning and manual tuning. do not, under any circumstances put the "Security" option to "High" when default is "Low" because it will not respond to above key combination.
or else you can log for assistance from philips support center (first link when you google 25HT2212/69R keyword). then they will contact you with a support personal of your area. and get disable the "Hotel Mode". then it will work as normal TV. good luck
