Question about AOC LM729 17" LCD Monitor
At power on normal display will appear but for a few seconds display will disappear. Cable seems to be ok. I tried another but same type of cable but still the same problem. My cpu seems to be fine if use with another CRT monitor. I'd like to resolder possible loose pins or connection inside the lcd monitor but do not know how to open the back cover. Please help if u have any idea on how to uncover the back of the lcd....tnx
It's seems you got a backling inverter busted. Need to replaced a new one or repaired it. To repaired you need to replaced a bad capacitors with a bulged on top of each caps. Not sure...just replaced all the caps...:) Ok! to open the back cover, there are 2 types to open it. First unscrew the 4 corner screws. If there are some... First type it from the back. After you had removed all the screws. Get a good grip on the bottom R/H side with both hands pulling as hard as you can on the 2 joints. 2nd type from the front bezel. Laid your monitor screen upward and placed a piece of clothes to proctect the screen from smudged. Used 2 hands to lifted up the edged of a bezel...do the same on the other side... After that just removed the screws...and that's how to open the front and back cover... Have a nice day!
