Excavated with Google from Philips website: " When a letter F appears on the right hand corner of the screen it means the television is in factory mode. To exit from factory mode, press the 'VOLUME -' and ?CHANNEL -? buttons on the TV set simultaneous for 5 seconds. " Hope this helps Michael Junge

First reset to default, if don't work look for firmware upgrade, then make sure speakers are set to on.Actually there is always digital audio output when there is any TV input. However when the digital TV is used, digital bitstream format is output (for 5.1 channel sound). When any other TV input is used, digital PCM format is output. This is normal and indicated in the owner's manual.
Set the receiving decoder in the stereo system setup menu (not the TV) to automatic digital audio detection, not PCM or bitstream. This will enable digital audio when any TV input is selected

SOURCE: Had a power outage now
sounds like you may have also had a power spike and possibly fried the tv. have you tried unplugging the tv for about 30 mins and plugging it back in? some tv's have built in surge protectors that need to be re-set

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both. In your case I'd concentrate on the power input board.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.
If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.
If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).
Most of the caps that go are 10V 1000uF or 3300uF.
I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.
As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.
