Hello evry1,
I'm hoping I can get some help on this problem.......

I've had my Viewsonic PJ501 for almost 3 yrs with over 2600 hrs on the bulb. The bulb blew the other day. There's a power indicator lite that emits yellow when in standby, green when in operation, and red when there's a problem. There's also a lamp indicator lite with the same functions. When the bulb blew both power & lamp lite went red.

I replaced the bulb yesterday and it worked great, like a new projector. We had watched a movie & played games for about 4 hrs.

Today I turned on the projector and the two (power & lamp) indicator lites were red. I checked the new bulb and it still intact.

Is there a manual reset switch?

Does anybody know anything about the internals?

Is there a site/forum/help dedicated to viewsonics?

Thanks in advance to all those that can help! =)

Thx 4 reply but.........

I already did that when I installed the new lamp. I thought maybe there's a manual pin switch somewhere on the projector.

Here's a video link to show what the problem is:

In case you haven't done it already I would pull the bulb out and put it back it in order to reseat it. Then reset the counter again. It doesn't seem like a ballast problem since it did fire up initially and ran for four hours...maybe a firmware problem where it's not retaining the reset value. Maybe someone else has an answer.

By the way, your video of the problem was an ingenious way to allow people to see what you are experiencing. Maybe it will start a trend.

Edit: You should check that your filter is clean and not restricting the airflow that cools the projector. Check page 22 (Table 11) in your user guide for the blinking light sequence.
