My Philips TV 21PT2664/00 does not keep the channels anymore. Could this be due to a dead backup battery? Where can I find this on the circuit and how can I obtain a new one?

please help Sad

Could be tuner related or micro processor related.

The set still works ok, except for the pre-programmed channels.
Any idea where I have to look for a battery near the tuner of micro processor, if any?
Is there a backup battery? I checked the board but there is nothing obvious that I can find. Where can I find a circuit diagram of this Philips TV 21PT2664/00
