Question about BenQ PB6100 Multimedia Projector
My lamp has only 408 hours on it and the screen is very dim. Is this a problem anyone else has had? Cannot imagine that the bulb is already bad, with less than 500 hours. Thanks.
This is most probably your lamp , I have had loads of PB6100 's that has even had less hours on the lamp than yours and needed replacement.
Keep in mind that the 2000-3000 hours they talk about on a lamp is just a rough factory estimate. The time you get on a lamp is determined by how you use the Projector - because at the end of the day the lamp is just like a globe in your home - it doesn't like being swithed on and off for short periods. This is a mistake most Projector owners make - by thinking they are saving the bulb's lifetime and switching it off for short periods.
You can take my word on this as I am a Authorised BenQ Service Technician.
I've had clients who got 10 000 hours on one bulb just because they left the unit running for longer periods.
Lamp Part No : 60.J8618.CG1
Easiest way to make 100% sure before investing in a new lamp is to take out the lamp by opening the lamp door at the bottom.
Check for any vein like looking marks in either white or black or a bubble on the shaft.
If you have any further troubles or questions , feel free to post another posting and I'll answer it for you ASAP.
