I have an atlas replacement lamp for my G-10. It has about 800 hours on it and is having a hard time to light from the start. it some times takes two cycles or about 8 strikes from when I press the operate button. Is it time to replace the lamp. I did not do any adjustments with the power board when I got he lamp new. My orginal lamp never exprience this type of problem upt ot 1500 hours before replacement.
