Well the lamp bug has resurfaced again after a quiet time. Projector wouldn't start this evening and the fan wouldn't turn properly - sort of jerking backwards and forwards. Turned it off, waited, tried again. Lamp wouldn't start. Did the same for approx five goes in succession. Lamp still wouldn't start (lamp/cover light on). Finally unplugged it totally and left it for 10 minutes. Tried again. Lamp started OK. Lamp has 150hrs on it. Is it my imagination or is this getting worse???
