Optoma Theme scene HD81 will not power up. The on / stanby light on the box just keeps flashing and appears not to send any power to the projector.

you need to reset the lamp timer, usually done by holding some buttons while turning on

Most problems with the lamps are covered in the manuels for these projectors , however none user technical difficulties are not .. ie where it is needed to open the unit not recomended to the untrained as a screwdiver in the wrong place can cause irepairable harm let alone death ?
To check if it is your bulb simply take the unit to an engineer for an estimate usually free at least you will know whats wrong and can go from there .. and if you do have a working bulb an ebay replacement is probably the cheaper conclusion to your problem ... regards Vortash

Hello!

After 2 years I finnaly solved the problem. There was a flaw in the lamp´s temperature circuit. A technician disassambled my BENQ PB8253 unit and fixed the problem. Charged me US$ 75.00. I´m in Brazil.

Hope this can help.
