External Monitor Cannot Turn on After Short Electricity Outage

Have a dell xps laptop that i connect an external monitor to. My main screen would be the external monitor and my laptop screen would be the secondary screen.


Im located outside the us and where im at, its very common to have power outrages. Thus internet going out and also electricity going out. But when electricity goes out, it usually isn't that long. Many times it would go out for a few minutes then it would all come back etc. Theres been few times when the outage has been much longer.


I would immediately know this when my external monitor turns off and when my fans turn off. Then usually it comes back again. Well earlier this happened and everything turned off. So when this happens, the power in the refridgerator is off as well. Then the electricity seemed to have came back on.


However, I then went to power on my external monitor and nothing turns on because i notice the external monitor didn't turn back on which is almost always does.


Its an asus 24' monitor and its this one

https://www.amazon.com/ASUS-VS24AH-...8447&sr=8-1&keywords=asus+monitor+1920+x+1200



Can someone tell me how do i fix this issue? I connect my monitor to my laptop with an hdmi cable. The thing is when have the hdmi connected, on laptop screen it looks like how it should look. Basically there is nothing there. I extend both monitors where the main screen is my external monitor. I do notice that when i drag my mouse from my laptop screen to to the monitor... the mouse disappears from my laptop screen which means that my monitor should be working right?


Does anyone know what i can do here? Also as of now my electricity came back but my internet is not working. However, why is nothing showing up in my external monitor? I do have occasions where my internet would be out but now my electricity came back. So why does my monitor not turn on?

 

went to device manager and under display adapters, it shows

intel r hd graphics 530
nvidia geforce gtx 960m


when i click on each of it, both shows the device is working properly. This is when i unplugged the hdmi cable from my externall monitor. Thus right now im only using my laptop monitor as the screen since if i connect it to external monitor, i cannot type anything as the main screen would be my external monitor but it doesn't turn on. I click on the bottom buttons under this monitor and nothing turns on.


Also i like to add that i only have 2 electric outlets where my computer is located. One i used directly for the external monitor. The other one, i used a surge protector since i plug few things into it such as my laptop charger and my internet modem. Thus i need a surge protector because i dont have enough outlets.


Can someone tell me what i can do here? That should mean it has nothing to do with my graphics cards right since it does show working properly? Nothing turns on with the asus monitor. I clicked on all the buttons under it... nothing shows up...

 

I like to add, I cannot just get a new monitor. This monitor is 1920x1200 resolution and i cannot get this here where im located.

Can someone tell me what i can check here? I will most likely going to the computer repair shop here for them to take a look at this if i can't get this issue fixed.

Basically i have to get this monitor fixed even if it cost a lot of money because i cannot just order this monitor and get it because im not in the us. The monitors here are not 1920x1200 resolution. Its basically close to impossible to get one of these.

I know that electric outlet where my monitor was connected to isn't the issue because i connected something else to it and it works.

I read online that it could be something with Bios? However when i click on the power button or any of the other buttons on the asus monitor, nothing lights up. So does that mean my monitor went bad due to the short electric outage. This is very frustrating.

The other thing would be use someone else computer to see if it connects to this monitor via hdmi? However most people where im located dont have a computer so that makes it even more frustrating. Of course i could do this at a computer repair shop. But can someone tell me advice on what i can do here? The thing that bothers me is nothing lights up on my monitor. I mean, it can't be the hdmi cable going bad right? Since when its connected to it, it does show my laptop monitor as secondary monitor? Obviously if its just replacing the hdmi cable that would be very easy.

So most likely its my monitor? I have to get the monitor fixed asap and now i dont know what to do.

 

If the OSD does not dsisplay then the display has an issue like an inverter or something. This would also act without displaying anything like it is connected but o course you see nothing. for the future get an UPS or at least a good power strip as the spike during an outage can be electronic device killers.

 

Yes. As TANWare mentioned, even without anything connected to the monitor the OSD menu should still function. It can't be the backlight only, however, since it'd still show a very faint image. To make sure of that; shine a flashlight on the display while accessing the OSD menu. If there's still no image whatsoever then it is most likely a fuse on the monitor's pcb has been triggered.

Remove the display from its housing and start checking the pcb for components labeled 'F'. If there's no labels on the board, then look for white or green resistor-sized items that are letter-marked. Set the multimeter to Ohms and measure the component; if it shows infinite resistance then it has done its job and needs to be replaced or bypassed. A big blob of solder right over the fuse will work, but is, of course, a temporary solution; the monitor will now be unprotected against the next spike. An smd fuse is less than $1. Thing is, they're quite small, so soldering skills and a bit of patience are required.

 

I wonder if it is something in the monitor power supply. This should be easily repairable / replaceable by someone proficient in electronics. It might even be a blown fuze. If you are competent with a screwdriver then get the back off and look inside (with the monitor unplugged). Look for any little glass tubes near where the power cable connects to the monitor. These should have a thin wire inside. If you can't see the wire then the fuze has blown (ie the wire melts). There are also surface mounted fuzes, but leaves those for the expert.

It's quite possible that the power outage was the result of the system tripping due to a surge somewhere. It's that surge which is most likely to cause problems to connected devices, not the outage itself, and the power supplies for those devices are the most vulnerable part as they are the first to receive any nasties coming down the wires. A simple fuze is the first line of defence.

hi what do you mean osd. Nothing turns on with my monitor. The power button when i click on it doesn't turn on. When normally you turn it on, it shows blue. What do you mean shine a flashlight on the display while accessing the osd? You cannot turn on the monitor. Imagine a tv that you use a remote to turn on the tv and it doesn't turn on.

well i cannot do any complicated things to the monitor like open it up as im not computer savy at all. I was looking for simple ways to see if it could be fixed. Thus anything complicated i go to the repair shop. Thus im wondering if its something very simple. I clicked on all those power, menu buttons and hold the buttons for seconds to see if that works but it doesn't. I read online just hold the power button for x seconds then plug back in but that doesn't work.

Okay so if its a blown fuse, thats simple to fix at a computer repair shop? If its monitor power supply, that is easy as well? So based on what i described, can my monitor be repaired? Such as what reason would it be where okay you cannot fix this monitor.

 

Also can someone explain this. Why is it when i connect the hdmi cable from my laptop to my monitor now, my laptop screen acts like it does when connected to my external monitor when it works?


Again my setup is like this. My laptop is on the left side of the desk. My monitor is on the right side of my desk. I then have a keyboard that i use... not the laptop keyboard. I use my monitor as my main screen. So everything such as desktop icons and everything is on the screen. Thus my laptop screen shows just the wallpaper etc. However, i would many times drag certain prorgrams and chrome pages to the laptop screen by dragging it. I have the monitors in Extend these monitors mode if you know what i mean.


So why is it that when i connect my hdmi cable to the monitor now, why does my laptop screen show a wallpaper and all my icons apparently go to the monitor screen? Of course you can't see anything on the monitor since it cannot power on. Thus if my monitor doesn't power on, shouldn't when i connect my hdmi cable from laptop to monitor, my laptop screen should show my desktop icons and everything? Thus still act as my main screen as oppose to a secondary screen?


Someone mentioned this makes no sense at all and i didn't thought about that either. Or is this normal?

 

I suspect there is something about the way that HDMI is designed which means that the computer can sense that there is something at the end of the HDMI cable even if that device is turned off (or getting no power due to a PSU problem).

I'm 95% sure that the problem is with the monitor's power supply and it could well be just a blown fuze. Take to a competent repair place. It might only take 10 minutes to fix (if a blown fuze). And buy another surge protector while you are there.

hi there. If its a monitor power supply problem, is that fixable? I read that if its a blow fuse, that is easily fixable. But what problem could it be where okay this is not fixable.


I will go to repair shop soon but want to know all this before i go there.

 

I'm sure that the monitor power supply is fixable, but don't know the cost. Some Dell monitors use an external PSU which makes replacement easy. However, if the PSU is internal then it might either be a separate module (which is likely to be a standard part producing power at fixed voltages such as 12V and 5V) or some components on a board in which case the repair person has to check through to find what has died and then replace it.

If you live in an area with frequent power fluctuations then fixing this type of problem is likely to be a regular job for someone who has developed well-practised trouble-shooting skills.They may be willing to look inside, check the fuzes and, if that's not the cause, give you a price / time for fixing the power supply. Check the price of replacement monitor options so you can decide on your budget ceiling.

Let us know the outcome.

I went to repair shop and was told there will be a diagnostic done and i will get a call back from them early next week. I asked so do you know what are the odds it can be fixed and i was told its about 50/50. They pressed the power button and noticed it didnt power on etc.


Yes so this monitor is Asus and not a dell. So im not sure if that makes a big difference or not.


Yes where im located there are frequent power outages. Most of the time its just a few minutes, other times much longer than that. But again each time this happened and when my electricity came back, everything would turn back on. So when my monitor didn't turn back on and my fans was on, i was confused why. I then look at my fridge and it was on so thats when i noticed this.


As for the replacement monitor options, they do not have this type of monitor where im located with this resolution. That is the main issue. If i could get it, well it makes everything simple as if they can't fix it, i just order one online and have it shipped.


But here, i cannot do this. Thats my issue.


So if its the power supply, its fixable. If its a broken fuse, its fixable. But if its a what... when its not fixable?

 

Went back from repair shop. They told me they cannot fix it. Said the board is broken. Does anyone know exactly where this is in the back of the monitor? He showed me but i forgot where exactly.





I asked so its not possible to fix it... they said it isn't possible.





So that meant even replacing parts on it doesn't do anything right? I didn't ask any more questions since i figured if they could, well obviously they would try.

 

They told you this without opening up the monitor, presumably ?

Of course it's possible; anything can be fixed. First thing is checking the fuses, but if they won't even do that much ... well ...

Look, if you want it fixed then bring it to a decent repair shop. Somewhere were they have more expertise than re-installing Windows, replacing hard drives and installing RAM. You need a place where they know the difference between a resistor and their own arse.

However, if they did open it up and actually tested the pcb then they should have told you it's possible to drop in a replacement for about $25 (+1 hourly wage).

The power supply on this monitor is integrated, btw; the power socket on the rear of the monitor is a giveaway. The power circuit has its own pcb, which can also be replaced for $25, in case it really is ruined beyond (economically realistic) repair. This is an unlikely scenario since it's pretty sturdy and the few components it has are quite large and easily+cheaply replaced with a little soldering.

 

HI there. I'm pretty certain they did open up the monitor. I left it there for few days.


That is actually the best tv repair shop where im located. I went to the best one. Basically this place is fixing tvs and monitors. The first place that i went to, they recommended me this place and this place that i went to has excellent reviews.


The thing is this. They did not even charge me for the diagnostic. When you go to places to get things fixed, usually you will have to pay a fee for diagnostic. They didn't even charge me anything for that. So based on what, don't you agree well they cannot fix it then? Are you 100 percent sure its possisble for the replacement thing which you are talking about? I asked him after he said he can't fix it, is there any way at all you could fix it and he said they can't because the board is broken.


I would pay more money than the monitor cost to fix this monitor. Im sure if they could fix it, they would tell me we can but it would cost thiis much money but they didn't. So based on that, what do you think? Can they really not fix it? Or they possibly can but the price would be a lot. Because if price is a lot, im sure they would tell me what it would cost such as parts etc. I have no issue paying it.


Thanks.

 

The $25+time should be enough, provided you can find the board ( here's one for $23, but shipping non-US makes it a bit costlier). Seller also has the power board for $23, clearly both are scavenged from a broken/cracked example. Alternative is buying a defective example of the same monitor and swapping the parts.

Either way, it depends on the value of the original monitor and what it'd cost to buy an equivalent replacement (used value, of course). There's some very good used displays for a fraction of the original cost, like this UltraSharp U3011t.
