    My LG L194WT monitor does not come back of stand-by mode. When I try to wake the monitor up, the LED in the monitor faceplate flashes in blue color in a very irregular rhythm.

It is probably indicative of a switched mode powersupply trying to start then seeing a short and then trying to start again...this will cycle continuously until fault is rectified..any component that can drain the powersupply is the culprit...you need some way of detaching the powersupply from the load (monitor) to see if the power supply its self is the cause and also check if there is a loop back (a pulse) for continuous running.

My L194WT -SF WONT WORK NO POWER USED SAME POWER LEAD ON DIFFERENT MONITOR NO PROBLEM


Hello Steve,

The most common problem with the L194WT monitors is a failure of the power supply board. There are parts called capacitors that fail and can cause the issue you have. Sometimes the power light will just flash, sometimes it takes several minutes to display a picture or even a wavy picture, all of these issues indicate a failing power supply board. These boards can be repaired if you can do a little soldering. The L194WT uses the same power board as the L196WTQ and we have a step by step repair guide with dis-assembly instructions available at http://www.ccl-la.com/blog/index.php/lg-l196wtq-bf-lcd-monitor-repair/ Look over the guide and check your board to see if your capacitors have bulged and need to be replaced.

I hope this helps, if so please rate our solution.

Hi, I turned my computer and monitor off as I normally do last night and when I came downstairs this morning to turn my computer and monitor on, my monitor didn't turn on. I pressed the power button on...


You need your monitor repaired or replaced.
Unlike a computer, there is not much troubleshooting beyond making sure it is plugged into a live outlet and turned on which you did already.
Good luck!

My monitor does not turn on and the power button light keeps blinking ... <my Gateway monitor light blinks blue slowly but the screen is blank


This is usually a sign that there is no signal going to your monitor, check all your cables and then reboot.

Hp cpus power supply green light constantly blinking


As always verify all cords are plugged in properly. After that it sounds like you power supply went out. It is not that hard to replace. Make sure you unplug power cord. After you remove the pc cover, Usually you just need to unscrew 4 screws for the power supply. Somewhere on the power supply it should say how much watts it is. Anywhere from 200 watts and up. Just replace with exact wattage.
