I have one 550 that is giving me some issues. A few weeks ago we burned out the lamp base. That has been repaired with a new base, and a new lamp has been installed. It worked great for maybe 2 weeks. Now once a day when the rig is struck it shows the LEER code and will not strike, however if I give it a hard reset it will strike up and stay on for the entire show. Does anyone have any idea on what is going on here? Any help is appreciated.
