Question about BenQ Projector Lamp for MX760 MX761 MX812ST

1 Answer

Benq MX761 stays on for only 2 minutes and then shuts down after genuine Benq lamp replacement. Picture flickers colour just before shutdown. Lamp timer has been reset to zero.

I'm sure the lamp is okay as I have tried it in another MX761. Its difficult to get it to start up after power-up. I do this by holding down the mode enter button.

Many LED TVs and other electronics have bad capacitors on their power supply boards. You can visually inspect them by opening the TV and looking for capacitors with bulging tops. If you see any, replace them all in the power board section. Check to see if your TV is still under warranty first though.

Testimonial: "Thanks for your reply, I have got to the root of the problem since i posted my initial query and established the following:- Initially i found it difficult to establish if it was a hardware or software problem but on further investigation on the hardware side I found a fault in the ballast circuit which drives the lamp so in summary the ballast circuit was able to fire up the lamp but wasn't able to hold it so the lamp cut out after two minutes. Thank you John"

The monitor is going down. If I take out the current and put it back then it works but only for a limited (irregular) time then shutting down again


You may have a faulty inverter board or defective CCFL lamp. A faulty CCFL lamp may have the following symptom: Screen flashes on and off or displays reddish pink hue. Picture stays on in red and slowly be come normal. Picture flickering and/or with dim display or appear black. Picture flickers on and off. Usually the CCFL lamp fails before the inverter.
The inverter board can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

Lamp is not coming on. It was replaced recently Benq 8720


Check in your instruction Manual about pressing a button sequence while starting up. Some projectors do not actually know when you have changed the lamp, so you have to reset the lamp timer by pressing a button sequence. Often a genuine replacement lamp will have an instruction set which comes with the new lamp ( If you still have it !! :) You may have replaced the lamp but not reset the counter and it has shutdown because the counter has reached a critical umber of hours.

My benq projector turns on for a few minutes (light and fan going strong), then it shuts down.


if it goes through shut down mode (lamp first and fans run a while), reset the settings to factory default. while you're in the menu, check the lamp hours (under settings). if they're close to 2000 hours, replace the lamp. if the projector shuts down immediately, fans and all, you have a power supply problem. you'll need to replace it.

Lamp will not stay on more that a minute or so. Why? All of the fans are working and none of the vents are clogged but it is like a thermal switch shuts the lamp off.


if the projector is overheating, it will shut down. blow out the projector with canned air. the dust keeps in the heat that the fans are trying to expell. if it has shut down from heat to often, you'll need to replace the thermosensor. if you are not sure it's temp related, check the lamp for bulges and black spots. replace lamp if necessary.

BenQ fp567 goes on a flicker mode and will not respond


The fault could be a faulty inverter or a faulty CCFL lamp.
The inverter supplies high voltage to the CCFL lamp, if faulty the CCFL lamp can flicker or not light up. The CCFL lamp is a mini fluro lamp, and flicks on and off when faulty especially as it ages.

Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
