I just register here to dig up this topic about the BenQ PE8720
Excuse my English, that's why I'm French
I'm still using the projector with a lot of pleasure, I never had the wish to upgrade as I'm so happy with it.
I calibrated it with a light probe from HCFR and the results are stunning.
I never had any problem with it along those years, except one lamp.
Last Saturday, I wanted to watch the last episode of Better Call Saul.
I started it as usual but it shutdown itself after around 30s to 1 minute. The "Lamp" led being steady red.
I then checked the lamp (436hrs), the fans and the dust filter. All fine.
Retried several times, but again, it always shutdown itself.
I notice there is thermal sensor in the lamp compartment.
And I start thinking it might be faulty.
If the VP doesn't have a feedback about heat coming from the lamp, it can think the lamp is blown.
Then it shutdown and light on the red led lamp.
What do you think ?
I contacted the BenQ support through their website chat.
But the guy here didn't help at all.
Arguing the 8720 was too old and a motherboard replacement would cost as much as a new VP.
I then asked if he can give some references for this thermal sensor but he replied they don't sell spare parts and doesn't have any references.
Well ... welcome it the world of consuming.
