When i turn on my NEC LT30, it trys to start op, but after 30 sec. it goes to standby mode and the status indicator is blinking red. According to the troubleshooting in the manual, the problem is: "Lamp Error" "Lamp fails to light. Wait a full minute and then turn on again".
But this dosen't seem to work at all no matter how many minutes i wait. I've also tryet to press the "Power ON" button in 10 sec. to reset the lamp. But with no luck. The lamp dosen't seem to be broken at all when i look at it.
We have had this problem with two of these. The first one was repaired by replacing the ballast board (NEC P/N 03N-10-0763), but the second one must have other problems, as replacing this part did not help.

According to NEC technical support, if the status light flashes red six times, this could indicate a defective lamp.
If a new lamp is installed and the project still won't turn on, the projector will
I had this same problem with 2 NEC VT595 projectors. My problem was that there was a broken "tab" on the lamp cover (the plastic cover that slides in place over the lamp) that is supposed to depress a switch which insures the lamp cover is in place before operating the projector. The tab was broken in half and not making the connection there for causing the blinking status light (.5 sec on, 2.5 sec off) indicating a lamp housing or cover error.
if the status light is blinking red in 4 sec interval it means that there is something wrong with cooling system. you shold check if there is a thermostat failure or if there are any switches that are not turned on. i suggest you to open the device (using screwdriver) and check if there are any switches broken or damaged.
i had pretty much the same problem (one second interval). i took off the cover and there was a broken switch and i just short-circuit it and now it works
There are different rates at which the status light will blink to indicate various errors.
