Question about ASUS MK241H Monitor

1 Answer

MK241H sometimes doesn't turn on

It's somewhat random.
Doesn't matter where its plugged on, its temperamental, sometimes the monitor doesn't turn on at all.
Sometimes after changing plugs it works. Sometimes after replugging power cable works. Sometimes waiting works. Sometimes its cold, sometimes hot, doesn't matter. Mashing power button nonstop doesn't work.
Tried finding something over the internet for this, but there's nothing, it seems like only me have this issue.
Still not able to find a pattern where I could tell if it would work or not without trying turning it on, because its so random.
Sometimes I lose like 20 minutes on this, sometimes 1, depends.
Thanks in advance.

    I had a previous LCD that I never had this issue with, and the computer is the same, so I doubt it's the CPU.

    Same thing happens to me. And I agree with the "random" thing. Looks like sometimes it doesn't want to switch on.
    It happened twice, the first time I just wait for the next day, and it was working; this time, looks like waiting doesn't solve the problem at all.

    I have the same problem..
    My monitor is dead.. Hmm, maybe because of temperature?

    I have the exact same problem. It is very frustrating, especially the unpredictability of the matter. It doesn't make any sense. Mine's still under warranty, so I'm thinking of returning it.

    I was very satisfied with my 20,1" ASUS monitor and had high expectations for this one too... Must say I'm very disappointed to see so many having this same issue... This is a really annoying and unnecessary problem. I expect more than this from a manufacturer like ASUS.. I'm going to get an RMA right away to return the monitor. Hope to get another revision of the product or something........

    same as me, I think its the bug of MK241h, no matter you RMA this product you will get the same

    I noticed an interesting thing.
    The power button is the rightmost one, sometimes I accidentally press the left button next to it and this issue aries. I don't know if the other buttons would act the same way, but being sure that you only press the power button before turning it on you won't have problems anymore.
    At least its still working for me.

    I tried switching it on connected to the desktop, to the laptop, not connected to any computer, with another cable, trying all combinations of HDMI-DVI-VGA... and nothing seems to work, it doesn't switch on.

    The source power comes from a UPS, so, the power line is clean and constant. I tried also to connect it directly to the power and I had the same result, doesn't switch on. No green or red light in the led, the monitor doesn't respond.

    Like I said, last time I had this issue (3 months ago), it was solved by the next day, and it worked without problems, but not this time.

    I'll try to get a new one calling Asus' support; this monitor has 3 years of warranty and it has only 8 months of use. What is really annoying is the fact that I don't have another monitor to work with... just a crappy old laptop.

Unplug the monitor from CPU Keep the monitor alone and see any problem. If not try to plug to some laptop and check again. We want to sort out the problem from monitor or CPU..

No power at all

If your monitor doesn't turn on, and you are sure of the power supply (some plug directly into the wall and some use a power adapter), then you can assume that the monitor has failed.
You can fix it (replace the power supply in the monitor itself or possibly the on/off switch), have it fixed by someone who knows how to do this, or buy a new monitor.
First, of course, be sure the problem is your monitor and not the computer. If the monitor light turns green and then yellow, you can assume it's the computer. If the monitor light doesn't go on at all, it's the monitor.

In the middle of reading e-mail the monitor went black, no flicker, no warning, no warning

First I would check to make sure it was still plugged in, you never know, things come loose sometimes.
After that check and make sure that the cable that runs from the back of the monitor to the back of your computer is still plugged in. If it's loose push it back in.
If that's still not working, try turning the monitor off and restarting your computer, and then turning it all back on.
If all that doesn't fix it, then it's probably just gone bad. So either get a new one or if it's still under warranty send it in for repair/replacement.

CRT Monitor-Compaq presario VM700

Hi Snandy, I absolutely despise monitor and computer sleep or hibernation modes. Before I started routinely disabling this on all the computers I supported my users were always having problems no matter how computer literate they were. I know this sounds simplistic and you may have already done it but have you just unplugged the monitor? If that doesn?t work maybe the PC itself has gone to sleep as well. Try moving the mouse, hitting a keyboard key. If that doesn?t work try pushing the power button on the computer to turn it on. If all else fails pull the power plug on the computer itself, plug back in and it should start up. I would suggest disabling all of this via Windows Power settings in the control panel. Let us know if you have any other questions and again please don?t forget to rate the post.
