I changed the projection lamp and now my tv keeps shuting down !try to re install it and it might work for 1 night than turn on in morning than 1 min later it turns off off on off off off its driving me...


It sounds like you might have an incorrectburner /bad lamp. If the Lamp is drawing more power than it should, it will overextend the power supply and the unit will shut off to protect itself. It is advisable to stop using it and contact the company you got it from.
