Optoma Projector

[Steve Butler]

Hi All,

I have an Optima Digital Projector model No EP757, when powered up standby
light flashes for a minute or so then goes solid for another minute or so
before return to flashing. Fans are not coming on at all either
Brand new globe, Techo told me there is a fault with a ground connection to
the DMD (or similiar didnt quite catch it) board.If i heard him right i
think he said it was a common fault. looks like a pig of a thing to get to
the main processor board and want to avoid stripping it if i can until im
reasonably sure its the main board

Anyone have any tips on this one? possibly schematics/service manual
