I have a Philips 19'monitor from 2007 which has a tuner, pc input hdmi, scart and av. When I start the monitor from power outlet it goes to channel 1 of the tuner. Now I have this monitor enclosed in a unit as I am using it as display for an arcade machine and it is a pain to change the source every time, even because the remote will not work because the monitor is behind a wooden frame. Is there a way that I can set the monitor to start by default on PC (VGA connection) which is the port that it is connected. I managed to get to the service menu but I do not think I can set from there. Can someone around help me please?
