I asked for paid repair, paid replacement, and even about purchasing original device screen so that I can repair it myself - but Dell said no for all.

Now, I’ve found this: https://www.aliexpress.com/item/40000838... but I’m not sure if I should go with this? Also, if I do grab this, then I cannot find a single disassembly instructions for U2718Q Dell monitor.

Can someone please help me with this?

Is there any spare part to check or anything else I can do myself to get it back to work.

Greetings

What is the problem with the monitor?

⟐ Answer accepted июля 31, 2018 at 23:49 GMT-7

Unplugged all leads and power to PC to get this going.

Don't know why this occurred.

Any ideas?

My Dell E193FP Monitor goes black after about 1 second after I switch it on. This applies for when I use the "on" button, plug it into the PC, change screen resolution in display settings, etc. It always just shows a picture for 1 second and then goes completely black. The picture I see for 1 second is good and there seems to be no damages in the picture.

Now I'm thinking, if I can get a picture for 1 second, can the screen be repaired?

Cheers,

Christian

I need some help troubleshooting an issue with my monitor, and I could really use your expertise. Unlike others with the same monitor, mine doesn't have any backlight. I've already checked the fuses and visually inspected the boards for any signs of burned capacitors, ceramics, or other obvious problems, but everything looks fine.

I decided to test the power supply unit (PSU) separately, and it doesn't seem to be outputting any current through the plug. I've measured each pin individually, but I haven't detected any current on the output. The main capacitor and all the medium-sized ones are holding a charge, although I haven't removed them from the PCB, so I'm not sure if my measurements are accurate.

Here's where things get interesting. When I plug the PSU back into the main board, I hear a faint clicking sound coming from one of the boards. I can't pinpoint exactly which one it's coming from, but the rhythm of the clicks is around 90 beats per minute. This makes me think that there might be a faulty capacitor somewhere that isn't burned, but isn't functioning properly either.

I have the necessary tools for soldering, such as iron and some soldering skills, as well as a multimeter for measurements. Unfortunately, I don't have access to an oscilloscope. While I could simply order new boards, I live in Vietnam, so options like eBay and Alibaba aren't available to me. If I can identify the specific component that's broken or burned, I believe I can find a replacement and fix it, rather than replacing the entire set of boards.

I'm determined to tackle this issue, but I'm not sure where to start. If anyone has any insights or if the clicking sound gives you any ideas about a direction to follow, I would greatly appreciate your input.

Cheers!

@oldturkey03 narrowed down the sound to an area but I can't be sure 100%

I think the sound is coming from one of these 3 components - but keep in mind that the card doesn't make a sound if not connected to the rest of the boards (somehow).

This is the side missing - I shunted it before I got the multimeter and the fuse just in case. but I will remove the shunt later.

Thank's a lot for helping out - I wish I could help the community more but my skills are mainly handcraft based - I was working for Airbus and Thales at some point in my life. But I was mainly following schematics and soldering on binocular prototypes... so my electronic knowledge is basically U = I*R

For the measurement of the plugs, I tried between black wire to all the colours without reading.
when I did measure between the caps in the red square I had oscillating readings (I'm using an old-school multimeter).

Cheers!

@oldturkey03 so I did just that. measuring between fuse and ground. I do have some voltage but its really small and it also oscillates at less than 0.5v

I have also measured the big cap 450v/100uf and its reading is pretty low too if it is supposed to be at 450v it's now at 255 and fluctuating.

On this image
Red arrow big cap = 255V (oscillates)
Green arrow small cap = 4.5v (stable)

White arrow = 0.3v (oscillates)

Purple and pink Purple is the GND and coloured ones have the same voltage = 0.3v (oscillates)

the test you asked for also shows 0.3v (oscillates).

in addition, I just made another test. I remove the rest of the cards I was wondering if unconnected the Psu card would still have the same reading- so first the Psu card alone does not click.

I made the same test as above and the readings are now better 450v on the big cap with no oscillation - 4.5v on the green arrow - when I measure the pins on the connector from purple to all the colours I have now higher voltages around 20v with no oscillation.

So I turned then I unplug the Led card from the main and plugged the main board back into its PSU magic the click is back and so are the low voltages. On the right side of the main board, the caps did retain voltages but on the left side they didn't (measured the big caps none of the ceramics SMC) so I kind of want to replace them since I have no way to test them my multimeter doesn't measure capacitors, it's only 3 guys to order before I give up and try to find a replacement card that can be shipped in Vietnam which is probably impossible...

You said earlier that maybe the PSU is sleeping when nothing is connected to it, and I have 2 pins white and grey that never showed any voltages should I try to short them to see if the click comes back?

can i pull the power supply board from the 1907FPC and replace the power supply board in the 1908FPT? i'm perfectly happy sacrificing the 1280x1024 monitor to resurrect the 1920x1080 monitor if the power boards are compatible.

Thanks

Hi folks! My boss was about to bin this Dell U2717D today, but I've brought it home instead.

I realise it'd need some manual repair (Dell don't offer monitor repair AFAIK, and their services are pretty pricey anyway), so I'd hugely appreciate any advice you might have on how to begin!

I'm happy with tinkering, but have mainly repaired laptops and desktops, never tried a monitor before.

Thanks in advance,

Tom

Good day I have a Dell E2316h that starts flickering after a few hours of use for the day. After a few hours the screen starts to flicker and jump. Could it be the mainboad or the PSU? I would like to know so I can order the part and not buy the wrong part. I have uploaded a video of the monitor flicking. The monitor also flickers alot when there is alot of movement on the screen which brings me to believe that it could be the mainboard. I am not sure and I have found both part on the internet but I want to buy the right parts without wasting my money.

The buttons that scroll through the screen aren't working at all. The buttons that scroll through the screen aren't working at all. It's a mess; it doesn't scroll, it doesn't work, and the screen doesn't turn on.
