AOC LM722 LCD repairs

January 27, 2007

100_1343.jpgOne of my real bad habbits is picking up faulty junk off trademe in hopes of me repairing them and making use of them, I just cant stand how people end up throwing away good stuff which only costs $1 to fix (no really, only $1 or even less!!!). Luckly for me, someone elses loss is my gain and also luckly for me, Ive had some good luck in this area, in this case, picking up this faulty AOC LCD Monitor for the cheap cheap price of only $45, Ofcourse, it did have this minor problem of actually being faulty.

The auction described the monitor as  “*****POWER PROBLEM WITH MONITOR, IT DOES NOT STAY ON! COULD BE AN EASY FIX FOR SOMEONE WHO KNOWS WHAT THEY ARE DOING.************”
After having it arrived at work in its original packaging (really must stress the packaging, once the screens cracked, or have dead spots, nothing left to do but dump the poor thing), I pluged it in and sure enough, the monitor would turn on for about 2 seconds and then nothing.

Suspecting the backlight as bing the issue, I grabbed a tourch and tried to see if there was a dark faint image on the screen, no luck, the monitor had actually gone on standby mode (indicated by the orange led). Further diognostics required taking the unit apart…. heres some quick notes on how to do this (without putting too much stress on the plastic and the actual lcd).
You will need only 2 screw drivers (one philips for the screws and one flat head, for best results and to avoid damaging the plastic, go for the widest flathead you can find) and a small spanner.

Ok, some pictures on removing the plastic casing.

A visual inspection quickly showed the croperit, the pluge of the bad capactors strikes again.
After a quick replacement of the cap, I quickly put the sheild back on and gave it a quick wheirl. Fixed!!!
Reassembled the casing and left the lcd running over night with a  screensaver. By morning, still running and has

been for over 3 weeks now.

Net Result? Dual Monitors!!!
