no picture condition could be caused by a problem in the horizontal deflection circuit or a power supply failure. A horizontal deflection problem often are followed by open fuses due to shorted components such as a h.o. transistor ofcourse there are a lot more componentd that constitute this circuit. Another no picture condition could be caused by defective convergence power amps. these amps usually give an clear indicator when they are about to quit(color curved or missaligned, double color images etc.) this is a common problem with projection tvs and that is where I would tell the tv tech to start looking.
