Epson EMP-74 - Blinking Red Light

This projector was working fine and as far as I am aware has over 1000 hours left. I switch it on (from cold) , it powers up (green light) I see the EPSON logo projected onto the screen and the menu's, then after about 45 seconds a high speed fan comes on, the screen goes blank, and the red light flashed every 1 second (the manual says this is an internal fault) has anyone got any ideas what the fault is ? is it going to cost me an arm and a leg to repair ?

    Hi Marrie,

    The lamp looks fine. The LED that is flashing is the Lamp/Temp (red) every 1 second. The manual says blinking every 0.5 secs is lamp/heat fault, every 1 sec is internal fault, this is every 1 second and the fast fan comes on after about 45 seconds from cold so doesn't seem like an overheating issue unless there is supposed to be a primary colling fan that is faulty. Others have suggested Poss Power Ballast or fan switch fault, any ideas ?

    Thanks again Marrie,

    I took it to a local PC repair shop who maintain and deal with the local school projectors and they have said there is a problem with the main board.

    My problem is where can I get a replacement board for a decent price ?

    I was told it would be cheaper to buy a new projector but surely there must be some spare parts around ?

    Do you have any ideas where I can go, phone, email, internet for the correct bits - I seem to have hit a dead end other than ebay but in the last 2 weeks nothing has come up. . .

    Thanks in advance.

    Hi there

    Firstly keep in mind that the hours they give you is only an estimate.

    Take out the lamp and check for any irregularity on it , like shape or discoloration.

    Could you tell me which LED on the Projector flashes ? Power or Lamp or Temp. ?

Hi Sootycat

Ok , most of the time this would be the Fan.Powerboard that is faulty then and unfortunatelly it would be better to replace the part rather than having it repaired.

Repaired Powerboards normally give the same problem a couple of months down the line.

Warning lights

Just so you know guys (and this procedure is not for the faint hearted!). I had the slow one second red warning light flash. I checked the bulb, which was find and I left it powered off for 48 hours. My projector is no longer under warranty and would have cost me over £300 to have it looked at. I ventured inside to inspect the boards, once I removed the main board to check the power supply I heard movement from one of the light ducts. It took me a while to removed enough to discover the fixing screw which holds the imaging cube in place (which is between the 3 light ducts and the projector lens) had come out (!?) and was rolling around inside the unit. This would also explain why sometimes I could not focus my unit properly. I remounted the imaging cube, put the whole thing back together and PRESTO! My projector is working again.
