So I've got this Epson EX5200 here that needed repair, its issue was no power. I had no problem fixing that and the projector turns on like it should, but there is one odd problem now that is appearing.
After pressing power, the power LED switches from amber (standby) to flashing green (powering up/getting ready). All that is normal and all but the issue is it just stays blinking endlessly.
I've worked on a few of these before, and I know that once the green LED starts blinking, the auto iris "initializes", then the ballast lights the bulb and voila.
There is no auto iris movement, no fans, just this blinking LED. The only way to turn it off is to unplug it and plug it back in.
I let the LED flash until it goes back to amber color, or about a minute. As for the ballast, I have no idea what type it is... other than an Epson? lol Otherwise im sure the projector works fine if I can get it to fully power up
Well okay, sorry I didnt get back, but I did check it out , removed a cable from the mainboard at a time, no change. I also swapped the ballast and PSU out from another unit with the same 2 parts,(but not the same mainboard) that didnt change anything either. Sooo I am suspecting the mainboard. I dont suppose theres a service manual for this little guy floating around?
