Waw, this topic still exists.
I just red the thing about the red flashing light club. I hope i'm still out of it but....i have some troubles with it.
First, my projector is the européan version called EH-TW4400 (don't know if it make any kind of difference).
Purchased a new lamp (généric structure, original bulb).
First replacement so far, first lamp lasted 2000h approx (small explosion, no glass shattered, cleaned it to be sure)
Cleaned dust, air filter, replaced lamp.
Nice picture. It's cool. After 25h, lamp stops, projector fan(s) turned to max for 30 sec, then turns off. Red blinking led (of sadness) at the lamp sign.
Thought it was the heat or something so i let it cool down 24h unplugged.
Turned it on, 30 seconds of light, goes of and the evil red dot cycle gets back.
After 3 tries = same failure.
Getting a new lamp soon.
My projector is about 4 years old. Never had a problem until replacing the lamp.
Any clues ? Am i part of the blinking hellred club ?
Thanks, really appreciated and sorry for the mistakes.
