I too have and turn knob on the side that doesn't turn it on or off any more when it was working it wouldn't dim to the lower setting and when it did it would act like it was getting ready to bust out the halogen bulb but it never did it just wouldn't come back on again after that I'd lobe to fix on my own if possible paid a decent amount for it if like to get as much use if I can? I had someone tell me it was the actuator or dimmer switch mechanism can you just buy new ones? Please help me :)
