Monitor goes to standby and loses signal

Rock N Roll Rebel · Mar 27, 2018

every so often her monitor will go black and its hard to get it to come back even on a reset it won't come back on is the monitor going out or is it the video card? I had her reinstall windows 10 home 64bit there is no video driver installed yet after windows reinstall and it did the same thing so it's not the video driver.
system specs the best I can remember
AMD FX 6300
ASUS N5XX EVO R2.0 MOBO I think not sure
ASUS GTX 960 video card
Ultra 1000w power supply
500gb hdd 1tb hdd

For ex? Seems to be a fitting system.

It won't suffice if you are the middle man in this problem, you need direct access to the PC. Ask her to bring the PC to a specialist.

If it ain't the monitor itself, it could be a lot... either GPU/PSU or the board.

Toothless · Mar 27, 2018

You're pretty nice to work on an ex's rig. Is it the monitor going to standby AND the system or just one of them?

uuuaaaaaa · Mar 27, 2018

I know that this will not contribute to solve the computer issue but It must be said.
I hope that you don't fall for her traps, she will just milk you to misery.

_JP_ · Mar 27, 2018

Guys, focus on the topic at hand. The "it's my ex" is only relevant to say that OP has no direct access to the system right now.

Anyway, I've seen issues like that arise from cables that go faulty too. Yes, the monitor could be on its way out, if it just shuts-off after a random period of time, but I'm intrigued about the "no signal" as you say. Is the warning shown at the screen?

+1

Reseat the cable and/or try a new one.
Also, check the power to the card and reseat the video card.

Well the first thing you should have had her do is check to ensure cables are tight and secure. The second was to swap monitors with another computer and see if the problem moved to the 2nd computer or not. If no monitor to swap with, most TVs these days support computer input.

Since you said this problem happens "every so often" it is highly unlikely it is the operating system so reinstalling Windows should have been the last thing suggested because it rarely works, and when it does, nothing is learned to prevent recurrence. Especially with older operating systems like W7, reinstalling can put the computer years behind in security updates, and then there's all the lost data, desktop and program configurations.

This could be heat related or even a power supply problem too.

What model is the monitor...

jboydgolfer · Mar 27, 2018

my monitor (which i never turn off) will sometimes (more so recently) not come on, meaning it wont display anything unless iturn it off & on , sometimes more than a few times, then eventually it (so far) comes back , and i get display. It is my panel shitting the bed. It was built in 2004, and is dying, but i will keep it until dying turns to died.

BadFrog · Mar 27, 2018

Does the monitor wake up when it's in bios and then goes to black screen?

Bill_Bright · Mar 27, 2018

This can also be a backlighting issue. While more common with CCFL (cold-cathode florescent lamp) and inverter LCD monitors, LED LCD monitor can have backlighting issues too. Next time it is displaying a black screen, shine a flashlight into the screen and stick your nose up to the screen and see if you can see a very faint image of your desktop. If you can, the computer is working fine and the monitor has a backlighting issue.

Another common cause for black screens is the monitor's intelligence circuits are failing and having a hard time syncing up with the card. It may be stuck in analog mode when the card is sending a digital signal. Or it is failing to sync to the correct resolution.

Again - swapping in a different monitor will easily and quickly let you isolate the issue to the monitor, or something in the computer.

I can't believe the idiotic "ex gf" comments, it has no relevance to the problem at hand and shame on you for thinking that once ppl break up that they can't continue to maintain a friendship.

Rock N Roll Rebel · Mar 28, 2018

thanks for all the help I'm going to see if her roommate has a computer she can hook up the monitor too to see if the monitor does the same thing the monitor is an old Samsung 22inch monitor that uses DVI
fyi she is my ex wife and we are good friends now

AsRock · Mar 28, 2018

OOh Samsung, the ones known for bad caps, good to hear you erm she can get the monitor on another system to check it. With you saying Samsung leaving the system running when it does it she could try turning off the monitor for a few minutes and turning it back on and see if it comes back on.

Rock N Roll Rebel · Mar 28, 2018

we tried turning off the monitor then back on most the time it takes a lot of times then it will come on. I have to wait tel her next days off before we work on it again she is working alot

bobodori · Mar 28, 2018

I also think it's the caps on the power supply board.Had similar problem with an old Samsung.Thankfully the repair is fairly easy if you have some soldering skills.But i don't think it's worth it

Of course they can. My comment was in the direction of OP to not get stuck with false hopes of getting her back because of doing such favors, it can happen, it happens a lot, you know it and in the end it can lead to emotional misery.
With this said OP himself said that she is his ex-wife and they seem to get along without issues, case closed. It is offtopic yes, but there is nothing wrong with trying to give a wake up call to a fellow, even if in this case was not necessary.

Back on topic I had a similar issue with a Samsung 2233rz 120hz monitor (in 2013 iirc) that was exhibiting similar symptoms. It gave me quite the headache because it turned on sometimes, and I almost bricked my motherboard trying to blind flash the BIOS, because I could not find the problem... I only found that the samsung monitor was faulty when I hooked up another monitor...

Yeah my NEC Multisync LCD 1700V from 2001 is doing the same, some say it could be the brick even besides the backlight or control board, I have to unplug and replug it 2-3 times for it to stay lit.

Time for another-

However I'm going to attempt a repair on this one if a brick doesn't fix it first. I'm only trying because of how long it lasted me before it failed.

P.S. To everyone here I'm divorced myself, don't shame the exes we have.

Rock N Roll Rebel · Mar 28, 2018

I was over there today and I replaced the cable and it still did it. her roommate does not have a computer to test the monitor on so she ordered a refurb http://www.sears.com/aoc-international-i2757fh-fb-r-27inch-aoc-i2757fh/p-SPM8574646727 I hope it works out for her. I talked her into canceling the order I don't think a refurb would not be good

Yeah especially AOC, go to a local shop or find a friend that has one just to test

GoFigureItOut · Mar 29, 2018

Are you using an adapter? VGA to DVI? I had this same problem long time ago. My monitor would go to sleep then wake up again. I just don't remember how I fixed it.

Rock N Roll Rebel · Mar 29, 2018

it was dvi to dvi now its dvi to hdmi

Good point, I didn't remember that one. Might happen too and cause random power downs.
The power adapters are usually made within 0 to 5% margin over the power consumed by the monitor, so if it develops a failure in the power delivery, the monitor refuses to work. I've replaced my share of those too, usually by more powerful ones, than the rated for the unit.

Once you go black, there's no turning back

Every morning I fight this battle. On off on off on off on off on! Finally!!!!

Normally it doesn't take more than 15 or 20 seconds to come on. Until the monitor actually breaks ,I am far too cheap to replace the damn thing. Plus I hate to see it go, it is a great monitor , WAY ahead of its time.

It'll be missed

Insert pictures of me & my monitor, in a slideshow, slowly fade in and out during video :laugh:

FWIW, something that helped in my situation, was to take the monitor outside, and use a Shop VAC to blow the dust and Debris out of it..
