lcd monitor automatic on off

There are 4 bad capacitors involved. It may not seem bulging but one or two are leaking. These are the 4 capacitors. 2 pcs. 470 microfarads - 25v 1 pc 1000 microfarads - 25v 1 pc 1000 microfarads - 10v I replaced them all. Next is to clean the board at the back. I got 91% alcohol and toothbrush and scrub. Concetrate on the 8-pin IC which has colored yellowish paste. Scrub or use a Q-tips buds soak with alcohol and clean it. Next resolder all 4 trasformers. Two on the primary and 2 from the inverter side. Also resolder the 2 transistor/mosfet (3 legs) which is attached to the metal (heat sink). After resoldering, again clean with alcohol by scrubbing or Q-tip buds for sensitive part.
Mine is working fine now. Good luck

Resolder the leads of the four TOROID inductors, make sure to remove the old solder, clean the leads real well and resolder. Also check caps for leaking/bulging tops and bottom seals, check the transistors (c5706/5707) for shorts.

How to open the back cover of the LCD monitor

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!
