Update BenQ PE8700

Hope this is not getting too old for you? I appreciate your help!
Spoke with BenQ again, still not helpful. They insist that it is the cable or something else and that there is no firmware upgrade for this or the PE 8720. Said the only reported problem was DVI to HDMI and that there was no fix at all for that.
Don't know what to do here???, I'm going to try and test it with another cable to see if it might be the cable but I bought a real high quality cable so I'm pretty sure that's not it and I know the cable isn't too long either.
This has been a real pain, I have this great projector but can't get it to work like it should.

    Hello, i have also the PE8700 and just added a Panasonic Blu-ray (BD30), connected via RGB cable (RCA connectors). The output of the bluray is initial 1080i and the native resolution of the projector is also 1080i - but it don't work like that - i have to reduce the output resolution of the player to 578i because the projector tells the player that's this is his max resolution via RGB? I think this is a firmware problem. But where can i find an upgrade for this?

Hi guys

All that needs to be done is a firmware upgrade.

This can however only be done by a BenQ Approved Service Provider because if the person doing this makes a balls-up the Projector will be dead as a doornail.

SOURCE: BenQ pe8700 projector ir sensor replace or repair

unless you dropped it, there is no damage to the sensor. it might just be dirty. blow the dust out of the projector with canned air. if there is physical damage, just replace it. if you're sure the remote works but none of the sensors do, it's a main board problem.

SOURCE: How do I replace the cooling fan in benq pe8700

There's more then one fan inside the projector. I think I counted 3 when I opened mine up. Two are easy to get to, the other is underneath. on theleft side looking from the front. You have to take off the back surround cover in onder to remove the top cover. The top cover slides back and lifts up. Be careful because there's a wire harness running to the top cover control panel. Disconnect it then you have access to the fans. Wish mine was that easy to repair.

Dear Sirs, I have a BENQ PE8700 projector. I know it's outdated, but it still suits me fine. I've already changed the lamp, and this new one is 1000 hours old. I am recently having a problem:...

If the bulb on this projector is filament less then it may be a bad ballast. If it is that kind of a bulb the ballast is like the starter on a florescent bulb that excites the internal gases for light to be emitted. If it conks out, the bulb stops emitting light even though the cooling fan stays on.

Hi there

A universal remote would do the job , as long as you make sure that the Universal Remote can learn IR codes which it uses to control the Projector.

Benq PE8700 - Won't Power Up

Hi there

Trust me that the Mainboard needs replacement.

I am very familiar with the PE8700's as I am a ASP Technician for BenQ.

Visit and look for the link to your country - you should be able to allocate a Approved Service Provider.

Must warn you that the Mainboards on these models are quite expensive.
