Changing startup logo LG/Zenith

I am trying to change the startup logo on my m4200 television, any ideas on how to do this?
thanks

I would love to do that to my 42" PDP. The big LG in the center does a bit of IR from time to time (goes away, of course) as I am still in the break in period.
Probably have to access it through the service menu.
