Question about Optoma DX605 Multimedia Projector
I purchased an Optoma DX605R replacement lamp and installed it and when I turned the projector on nothing happened. I usually get a OPTOMA display and then the picture appears, but now I get absolutely nothing and the light on top of the projector nesxt to the word "Lamp" flashes red once and after that, the machine eventually goes back into standby.
Ok, so forgive me, I'm going by memory. Take the top cover off (4 screws on the side). Take the top silver shield off, look at the screws and only take off the ones you need. It's ok if you take more off, but its just more screws to track. You will need to take off the back outer cover. You will need to unscrew the hexagonal screws that the vga-out port uses to screw the connector to, as these are holding the back plate on. Once you get in, the board you need to look at is on the bottom back. Look for a capacitor that has a rounded top, not flat like the others. You will need to replace this with the same voltage and capacitance. Try an electronics site on the internet to get the right replacement if you cannot find it locally. Sorry for the poor instructions, but its just been too long. As a practice, take pictures as you go (during removal of parts) and you can use them to reinstall. Hope this helps as mine is still working.

SOURCE: The optoma hd72 projector lamp
I had this exact same problem. I have changed bulbs gotten 1000 or so hours from new bulb, changed the lamp driver and gotten about 600 more hours from new lamp driver. New lamp cost me $350, lamp driver cost me $120. Then I read on a page to try and flip it right side up, because I had it ceiling mounted upside down. I flipped it right side up and it works perfectly and has been working perfectly for 2 months now. I know it sounds stupid, but it actually worked for me, and it costs you nothing to try it. For some reason, gravity effects this unit.

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
