Question about Optoma EP755 Multimedia Projector
Plug in turn on main power switch and standby power light flashes. Then press power button and power light will burn solid for a few seconds then goes to flashing again. No other sign of life. Can you help? What is a normal symptom if the main lamp fails to light?
Does the main lamp light at all? It sounds light a cooling fan failure. If the fan iis not working the the main lamp will not turn on and the power light will flash.

If the lamp usage time has passed 2 000 hours (when LAMP POWER has been set to NORMAL), the projector will switch to standby mode after approximately 10 minutes of operation. The resetting procedure should thus be completed within 10 minutes.
1. Insert the power cord plug into the wall outlet and then
press the MAIN POWER switch.

then press the F or G button to select the OPTION menu.

This will reset the cumulative usage time for the lamp
unit to zero.
