Check fan cable

Ok SCART is meant to be a "Standard" meaning all SCART should be the same, unfortunately they are NOT. Please have a look at the Wiki link below it will explain all. Some SCART plugs do not have all connection wired through, you must ensure your SCART cable has EVERY wire intact, we usually meter out our plugs to check, as we have been caught out too many times, usually the High end, ones are OK

I have had the same problem with 3 Sony VPL-EX1s and Sony will not answer emails regarding the problem. Hence I wont be purchasing Sony projectors again.

my sony vpl ex3 will not light up, has a lamp/cover light on all the time can somebody help

the cover switch is probably not fully made.
Ensure that the cover tangs are pushing the pin
on the miniswitches.
Try putting slight pressure on the fan or lamp cover to see if the lamp/cover light
stops flashing.
you will need to do a restart on the PJ to check this out

To reset the lamp timer:
1) With the projector plugged in and turned off, press the 'ON/STANDBY' button to put the projector in 'STANDBY' mode. NOTE: You have to press the button on the projector itself, you cannot use the remote for this step (this is not clear in manual).
2) Now, using the remote, press the following keys in order: RESET, <--, -->, ENTER.
3) Timer should now read '0'.
