Ok my bulb started to pulse the other night and made everything work crazy. I hope that is what was causing my LCD to flicker cause Lcd is fine now. I turned on light last night and bulb got about half lit and kicked the breaker in the house breaker box. Dont know why the breaker i got from LL store didnt kick fisrt. Anyways ever since then the bulb wont fire. How do I know which is bad ? And if it the ballast anyone know where I can get a new one besides the one at LLstore?
