    While i was using the computer the monitor screen just turned black.
    It is still switched on but it doesn't display anything on the screen.
    And i can hear ticking noise on it. It guess it was due to Q901 transistor.
    But i still didn't do anything, except take a look on the inside of the monitor
    searching if there is any components that smelled burned.

Open the monitor and check for cold solder and broken solder then re-solder it, you can find more of it just by looking for the brown colored pcb (pcb turned brown due to heat generated by parts soldered to it such as power transistors, power ICs).And look for the 5 pin IC then re-solder its pins. Prolong use of such monitors with that kind of problem can damaged the horizontal output transistor. So fix it first.

AOC color monitor model 5En...during power on all led lights blinks then stops blinking without display action. all led lights on no more action observed.


actually if u repair an aoc monitor alone without getting connected to cpu once u switch on the monitor all led's will lit on ( green light ) it will remain on situation until u connect the vga connector to cpu that's the time led's will lit off and only the power led will remain in green condition.some aoc 5en once u power on power led is in green condition and if not connected to cpu it will be in orange condition.hope u get some idea but i am not sure if it will work with ur monitor. but as long as LEDs lit on i think no problem with ur monitor.

AOC 53N PROBLEM


DO YOU KNOW HOW TO SOLDER. IF SO, TRY TO OPEN THE MONITR AND LOCATE THE VERTICAL SECTION AND YOU WILL FIND LOOSE SOLDERS. A SINGLE HORIZONTAL LINE MEANS THAT THERE IS A PROBLEM WITH THE VERTICAL LINEARITY OF YOUR MONITOR. FIND SOMEONE WHO KNOWS HOW TO FIX COLD SOLDERS
