I have been using all 3 up until now, however, both side monitors have stopped functioning correctly.

First the right side one, and then the left side one stopped working properly however they still work for a short period of time when turned on.

What happens is: After turning them on, the white POWER LED in the middle starts flashing in a sequence of 2 long blinks and a short one, it does this for about 2 to 5 minutes, then it turns OFF. Both partially functioning ones do the same. while the middle one is just fine for now ?

It appears that they go into a power saver mode, tho none of the Monitors are configured to do so, nor is Windows 10. (Performance mode, set to nothing ever turning off)

If I move one of the partially functioning ones to the middle, plug the same cables in they do the same, so I’ve concluded it’s not the DP (Display Port) connection nor the POWER BRICKS that are the cause.

There is ONE video on these Monitors having a similar issue, which has to do with its cooling fan in the base, however, when I power the Monitor on, I can clearly hear it spin up before it quiets down to normal operating volumes.

I have no idea what might be the cause and if it’s something trivial, I don’t really want to go out and buy 3 new Monitors yet.

Does anyone have any tips as to what the cause might be?

I have a new display Samsung 32¨ curved LU32R591CWUXEN. Since I have installed this display the pc never started the display at the same time.

Once the pc is switched on, the display doesn’t start with it and I have to push manually the switch button on the display if i want to see the desktop.

I have set up the Manual detection conexión instead automatic and did not work.

I have tried both cable conexion like HDMI and DisplayPort, none of them is working well. I also installed the original drivers from Samsung for both conexions, HDMI and Dp.

Before using this display I used to have two monitors Philips and they run very well with the Nvidia Geforce 2060 RTX.

I dont know what could be the issue.

I scratched it taking out the shattered screen, glass got into places. The display itself now works great but you can see the scratches on the top diffuser sheet.

I’ve looked around and made some inquiries, but it’s really difficult to purchase just that backlight.

Any suggestions?

I have a monitor where the top 1/3 of the screen is dimmer than the rest.

The kicker is, when I give the monitor a good smack or tilt it to the max, it goes back to normal.

Is this a lose cable inside? Lose CFL? or symptoms of a dying LCD panel?

Thanks,

Mike

Note: My monitor has symptoms similar to this individual's post LCD display is dim at top (see pic) pbg4

I have a problem with my Samsung T190 monitor: one day i turned it on and it was just darker in half upper screen.

I noticed a burning smell at the top rear of the device too.

Making some web search I found that my CCFL lamp should be burned.

What do you think it can be? If it is CCFL, do you have any video on how replacing it in a samsung monitor?

Thank you.

This has happened both for PC(hp laptop through HP USBC dock to DisplayPort) and Mac(M4Pro MBP through a Tripp-lite dock to HDMI1).

It feels like a software/firmware issue, but I can't find any firmware updates(if they exist, Samsung's support website is...meh).

Anyone have experience/insight?

When unused for few days, monitor flashes brightly then goes black. Passing heat over display (eg. using hair dryer) fixes but it's getting worse. I need to keep hair dryer on monitor for longer to get it working again. Once working, it displays fine once I don't stop use again for extended period.

Samsung tech repair center can't confirm cost due to uncertainty of which part needs replacing. What part could it be and how certain is this? Also, can I repair on my own? I am not an electrician but can screw in a light bulb, use a screwdriver and other handy things :)

I have no idea as to what could have happened to cause this problem.

Firstly, it does not appear to be a problem with any inputs (i.e., HDMI inputs) as the issue seems to be native to the screen itself.
I have tried unplugging all HDMI connections to the monitor, as well as leaving the monitor unplugged for a long period of time before powering it on again.

I have also tried resetting all settings on the device to no avail. The built-in trouble-shooter simply recommends to speak to Samsung about repairs. However, I would much prefer to resolve this issue myself (if possible) before I resort to the Samsung repair route.

If anyone has advice, fixes, or any suggestions it would be greatly appreciated.

Thanks,
