ITC 250. Plug it in power led doesn't light, press power, after waiting for unit stabilize time, led lights, then goes out three times as unit "tries" to start. Hear "pop" in speakers, no arc at spark gap in ballast power supply, lamp is new, as unit is new, never worked right out of the box. +390 volts DC to ballast supply, & tries three times. Lamp has + 65 volts approx while unit tries to start. After three tries unit show code ten then one. Ideas? Can't get manufacturer on the phone, thr B2B thompson site has no real info on that chassis. Sky.
