Thanks for that Shozzer. You are right. I'm in the UK and for regulatory reasons Sony cap the max volume to a pretty low level. It is possible to service setting of the player and change the country setting to US or another country where the cap is at a higher level. Only problem is that I just cannot get my player to go into the Service mode. Apparently the instructions are: To enter service mode: "Set the "HOLD" switch on. While holding down the GROUP key instead, enter the key sequence: >>| >>| |<< |<< >>| |<< >>| |<< | | | | i.e. FF FF REW REW FF REW FF REW PAUSE PAUSE Release all keys. If you have successfully entered service mode, the display will alternately display the firmware version in the left display and a screen with all LCD segments lit at about half second intervals. " What you need to do is find the value for code 113 and change it from the European code (81) to the US code (21). You should have the remote attached as the larger screen makes this easier. As I said I just despite me trying for hours I just cannot get my player to go into the Service mode. Does anybody have any ideas?
