Need to change the region code on panasonis SA PT850 home theatre system to all regions?

Your home theatre, because it's a BR player, has been made specifically for that region - the region for both the DVD and the BR is hard coded in the processor chip. Because of that there is no other region to switch to so you would need to replace the processor to change the region without making it region free.
Sorry, there is no way of making it region free.
