BENQ TFT monitor T905 doesn't work

Hello,

I have a BENQ TFT monitor T905 from a few years. Yesterday I turn on the monitor but It does't work. When I turn on the monitor the LED is green for a while (but doesn't appear the welcome message), after some seconds the LED turns yellow. If I turn on the PC the LED turns green again and maintain this state.

First of all I need help to open the monitor.

Thankyou in advance

Fist check the fuse on the inverter board if it is blown replace it if not you need another inverter board as it has fried. But I looked and was unable to find a new/replacement inverter online so I wish you the best of luck

Check for blown MOSFET IRFU9024N and transistors C5707/5706, and fuse in the inverter circuits section. Also look for bad caps with bulging top/seal. See some pictures of failed Dell monitors (BenQ made alot of monitors for Dell), http://s807.photobucket.com/home/budm/allalbums

I have a 15 inch BenQ FP731 monitor and its been working all fine for the past year, until yesterday. I have an Acer laptop hooked up to the monitor as its screen was wrecked so I just kept the display on...


This because your ACER laptop having higher resolution than your monitor. Please lower your ACER laptop resolution as low as possible then try again.

I received a benq t905 from my parents the other day and i just hooked it up to my computer and it won't work. everytime i press the on button it blinks green and makes a quiet beeping noise and then...


On rereading that post, I note that it shut itself off; perhaps it is time to open it up and fix it (if you're up on your electronics safety) per the _stinks_ note, below; you get to resolder some stuff running the backlight and replace a couple of standard capacitors and transistors, from what I can tell.

Things sound sort of normal for a driver being finicky about DVI modes; did the monitor driver not install, or just not bring visible results? You set your OS to 1280x1024 having booted to VESA (safe mode,) right? Normally when the resolution/sync is out of range, the status light is green constantly and you get a little note; maybe it's just too far out of the 56-76Hz video rate for that.

It's also possible that your backlight is failing (they fail short, as in too few ohms) or the monitor settings are set incompatibly...DMI or VGA cable? Does it stink?

Try to plug into another computer and wait to see.
If it turn up to be same it somewhere defect from the main board of the lcd.
If if not the same turn up to be, you should reinstall the OS because the software is corrupted or your display card problem.

Benq FP71G+S NOt starting.


Hello
I have had this problem twice once at my school and once with my BenQ FP71G Monitor. At my school the monitor ( HP ) just stopped working and smelt like burnt popcorn.(though is think this is due to some kids chucking a soccer(football) ball at it! With my BenQ it has the same problem though i nownthink it is because of the monitor has been on for excessive hours ( 3-4 ) and just shut down because of overheating. I will see in a couple of hours if it works !
