If all other functions can be adjusted then most likely the eeprom data may have corrupted.

I have an Optoma projector model EP732. One of the voltage regulator in the power supply module exploded. I have no idea what the part no. is. I've tried searching schematic diagrams in the internet but to no avail. Do you have any idea what could be the part no of this voltage regulator? Appreciate your help.....Thanks

Try check all the components in primary section especially the e-caps. Make sure also the components used are from the original part number.
