Having problems with your AOC LM729 17" LCD Monitor ?

Monitor problem Monitor powers on and displays an image for 10-20 seconds then screen goes black but power light stays on.


Answers :

You are experiencing an inverter board failure. You will need to replace or repair the inverter. The inverter drives the CCFL lamps that illuminate the screen if the lamps draw to much current or components on the board are overheating it will shut down the backlights. Some monitors have cold solder joints on the toroidal coils of the inverter that causes this problem, very typical with HP monitors, If you are handy with a solder iron you may try just re-soldering board and replacing push-pull transistors for a few more years of use. Provide make and model and I can be more specific about probable cause and solution.
Its looks Bad CCFL lamps or a faulty TL1451 smd IC when power shutdown in 2 to 5 5 sec.
