Help with monitor!! URGENT! - Page 2

Hailscott is right, and the only way to fix it (besides thumping the side) is to have BenQ (or certified rep) replace the backlight. 3yrs old, definitely out of warranty

Something that's pretty common in LCD monitors is that the inverter circuit which drives the CCFL backlight lamps also monitors the current of the lamp. If the current draw becomes too high, it shuts down the inverter circuit.
The most common cause of a high current lamp is age, as they get older they draw more and more current until the inverter goes into a failsafe mode to keep things from catching on fire. Replacing the inverter does nothing.

It is possible that the inverter just died, but its more likely that there is a bad lamp in there (usually 4 of them total unless you get into HUGE monitors). If you take it to a shop they will assume, and want to replace the inverter, at your cost, and it may not fix it due to the high current lamp issue.

What size monitor is it? $65 just to check it out? Probably better to just replace it and have all new parts

Another thing. Sometimes there is a fuse that is linked with the backlight, sometimes the fuse can blow. You would have to dissamble the monitor to find out though.

Chances are that the cost of repair will be close to or over the cost of a better/ new monitor. Keep in mind that when paying for repair you are paying a trained tech, who prob went to MIT and expects to earn some $. Time to get a new monitor, or try to fix it yourselff. You can poss find the same lcd on e-bay that has a cracked screen for cheap. Just make sure it is the same model#.

I don't a single computer tech who went to MIT

What size monitor?

65 to check it out? Sheesh!! Tear that puppy down and see what makes it tick!

I was able to find a backlight for an apple monitor for pretty darn cheap...but I tell you what, they made the monitor like a jigsaw puzzle. Got it apart just fine, but what a time I had putting it back together!!!! (Take notes if you have to!...or pictures)

It takes 10 mins to take a monitor apart. Then just remove and test each CCFL tube. Then use a multimeter to test the circuit. You can teach a monkey to do that.

No the purpose of high repair costs is to deter people from repairing equipment. I worked in a warranty repair shop for consumer electronics (everything, every brand) and when you consider the costs to replace the logic board on a cannon BJ-200 printer is $250, and the printer was a $90 printer, it's kind of obvious what they're going for
