SOURCE: LCD monitor shuts down every after 2-3 seconds

dustcore025, Need a little more info here. Do you know age of monitor? Was it or did it display a "perfect' image on it the day before? Is it under warranty? How far are you willing to go to try and repair this thing? Do you know how to "part" the snap together plastic back cover from the bezel, after removing the pedestal? This sounds to me like a Switch-mode-power-supply or Inverter problem that occurs when some Electrolytic Filter Capacitors get a little bit TIRED of being constantly subjected to high temperatures near heatsinks that are used to keep semiconductors within operating limits. You can determine how bad this may be if you can do a test and remember what happens. Here is what to do. Make sure PC is fully booted displaying WIN desktop or some other screen. Next, with someone to keep hitting the CTRL or SP bar key every 20-40 seconds while you reconnect both cables of your MM17 back to the PC video port and ac outlet. Now try to turn on the monitor and note exactly what you see and for how long. Did it have a sharp clear image, even for 1-2 seconds? did the screen go black? OK! Next thing is to shine a bright flashlight onto the screen 2 inches away from where you know there was something a few seconds ago. Try it at different angles and not if you see anything. get back to me with results of test. I'm louie12fix on fixya or lmistyrel @ aol.com BYE for now.

this kind of trouble is very common to all LCD monitors. your inverter is shutting down. please check all capacitors at the power supply some are badged or blown on top due to hot pressure inside.

SOURCE: Have a dell e177fp monitor. When I power on it

You probably have failure in the inverter circuits due to shorted transistors, bad solder joints, bad caps. Please see my pictures here so you will know what to look for inside.

Hello,

This is a very common symptom of a failure of the filter capacitors in the power supply board. The monitor is repairable, you just need to replace the 7 capacitors on the power supply board. Here is information on the board and the capacitors needed to repair it.

How do you get rid of a stuck green pixel on a benq e2200hd? ive already tried software fixes


Missing pixels are common on any LCD type of TV. The only way to get rid of it is to replace the panel itself. Do you have any kind of warranty?

Monitor displays breifly then goes to blank screen


The green power light indicates that the monitor is receiving from the computer correctly. I suspect it is going into high voltage shutdown. There is a safety circuit that monitors the high voltage and shuts the monitor down if it sees anything amiss. So the monitor comes on and then shuts off. High voltage problems are generally not worth trying to repair. Another example of a worthless safety feature. High voltage failures are not dangerous, and adding the safety circuit just kills the unit when it may have some life left or worse, sometimes it is the shutdown circuit itself which fails!
Hope this helps.
