LCD projector shuts off durning use
u have not mentioned how long u have been using this projector. either the lamp life is low or the circuitry protecting the lamp temperature is defective or even the air intake of the fan is inadequate, a filter is fitted for air flow if this is clogged or blocked, lamp temp will rise and unit shuts down. if lamp indicator is yellow or red it is time to change the lamp. if it is red - lamp is totally out, if u turn on the unit four times without replacing lamp, the unit simply wont turn on. one other possibility is power cable and power connections. check power cable too.
