Question about Samsung SyncMaster 940MW 19" LCD Monitor

Samsung-SyncMaster-940MW power problems

The monitor takes an extremely long time to power on, and it seems to take longer depending on how long it was left off. I have to hold down the power button for a minuet or more before it turns on, and if it has been left off for hours it can take quite a while before the light even starts blinking. The speakers make a popping sound as it turns on as well. I have tried different power outlets, but not different power cables.

    Monitor took an extremely long time to power on, and now doesn't power on at all. Initially, I would have to hold down the power button for a minuet or more before it turned on and would take quite a while before the light would start blinking. The speakers make a popping sound as it turns on as well. I have checked all the power cables

On and off switch not working


Hello Michael,

The most common problem with the Samsung 940MW units that don't turn on is a failure of the power supply board. There are parts called capacitors that fail which in turn causes the power supply to not startup correctly so the monitor never powers up. Here is a link to a repair guide that should get you back watching tv and using the monitor in no time.

Hello,

The power-up problem you are having is usually caused by a failing power supply board. There are parts called capacitors that will exhibit this type of problem until they are warmed up. As time goes but after they start failing they will take longer and longer for the power supply to stabilize before you get a picture. If you can solder then you should be able to do the repair yourself. We have a step by step repair guide that should get you going posted on our site at: http://www.ccl-la.com/blog/index.php/repairing-the-samsung-940mw-lcd-tv/ If you don't want to do the repair yourself, we do offer a repair service for this model.
