I have a Panasonic PT56DLX25. I just replaced the bulb on it today. Lasted well over 3 years, I was pleased. Anyways, there is a message that pops up everytime the tv is turned on. Please replace lamp and reset the lamp meter. I was told to Hold the volume down button on the tv and then hold mute on the remote. Don't have the original remote, but have all buttons on my ProntoPro. This method is not working. I need to reset it in order to get rid of this message. Any ideas?
