Hi, I was wondering if anyone here knows of or have experience opening the 34UM95? Mine has recently started to randomly blink in and out with sometimes loud pop noises from within the display case. I suspect the control board where the plugs are located is going bad, perhaps a capacitor or the DP weakening due to pressure from the cable. However, whatever it is causing the problem does not cause a disconnect as any open apps remain as is (versus moving around like when the display goes to sleep).

I can replace the control board but was wondering about taking apart the display. It seems to be all plastic tabs (no apparent screws) but I am wary about starting in the wrong place.

Btw, LG told me I am on my own since the display is already 2 years old and most of the computer shops around my area almost laughed when I asked about repairing the display.
I am pretty handy at opening and repairing electronics but I really don't want to mess up the display more than it is.

Thanks in advance.

Hey cykes,

The display is very easy to open. Once u get that back panel off the control board is right there and easy to get to. I would recommend starting In a corner and then work your way around. Also one thing I noticed is when I was doing it with a flat head screwdriver is turn to the left to undo the clips where as turning to the right made the screwdriver dig into the soft plastic frame making ugly marks lol. Good luck!

Hi Cykes,

I have the UM95, and I actually just had it repaired at my home by an LG tech for the exact same issue you are describing. Taking the back off is very very simple. Just use something flat and somewhat wider than a flat head screw driver to pop the panel off. This will help in reducing any marks on the housing.

I had my control board replaced the first time, and then on the second visit they replaced the entire panel and the t-con board. I still get the pops on occasion though even after those replacements. What I actually suspect is it being something with the speakers that are in there. I don't know how or why, but that's the last component of my monitor that wasn't replaced by LG. Considering that everything else is new (even the power supply and DP cable), that's my last guess.

I haven't done it yet because I'm lazy -- but I'd suggest popping the housing off and disconnecting the wire for the speakers from the control board. Put it back together and give it a bit to see if you still have the issue. It just *might* save you some money from buying a new board.

Here's a picture of what things look like with the back housing off.

Thank you Shred and Blam! Your comments really help.

Blampars, was your display going off and on randomly too? That is what mine does for about a couple of seconds every other day. Sometimes it happens with the loud "pop-bzzz" that makes me think something is arcing inside, but perhaps it is one of the speakers... :/

I am going to go ahead and replace the board. Just found a replacement on eBay for $47, hopefully that will solve it. Better than getting a new one, well, less expensive. biggrin.gif

Yes, but only a few times a week will my screen just go off/on. Kind of like it lost signal or something -- I don't know what causes that. Especially since both the boards in mine have been replaced, as well as the panel.

The pop-bzzz - I get that 1 to 2 times daily, and I think that has to do with the speakers.

Don't use a screwdriver, use a putty knife if you have one, or another flat wide tool so you won't mar the bezel. Once you have it started, guitar picks work great to run along the edges and release the rest of the tabs. The popping noise usually indicates the circuit running the led backlight has an issue. I hope it's not the led strips inside the panel. I don't remember if the power supply is external or internal but I have seen bad capacitors on both types. Capacitors arebfairly easy to replace.
It's too bad all the service shops in your area suck. We would have no problem repairing that monitor for you as long as we could locate any parts that might be needed. Good luck.

So, my LG 34UM95-C is driving me crazy. Is there ANY WAY to disable/fix the problem with the constant OSD message:
Code:
Power is off in 5 minutes to save energy.
Press any button to prevent the power off.

I need to constantly press the button on the monitor to "keep it alive" and to not let it power off. And what "ANY" button is it talking about, theres only one button on the f***ing thing!
It is the most annoying **** I have ever encountered with a monitor, ever. It does not matter what I am doing, working, browsing, playing games - whatever - it just decides for f*** knows what reason, that I am AFK, I guess...
Please, tell me, there is a fix for this crap.

Otherwise, love the monitor itself.

Thanks in advance for any help.

That's bizarre. I wouldn't have thought it would do that without the computer shutting it off by removing the sync signal. Have you tried resetting it back to factory in the menu? You may also want to try another cable, especially if you are using display port. You could also try moving to a DVI Dual Link cable if your video card supports it. Any of those things may correct the problem. There could also be firmware corruption causing the issue, or even a video card driver conflict or incompatibility.

Just got my LG34UM95 monitor off another guy. This monitor is really nice! Wish he sent me the stand screws. Seems they are missing. But I had an Ergo arm I bought just for this monitor so it's not a big deal. Anyone have any recommend settings for color and stuff? I noticed DP 1.2 was turned off so I turned that on since I have that and a cable that supports it. Not sure what benefit I will get from that.

Also, I don't have a USB cable yet for the monitor, had to order one since that also didn't get sent to me by the original owner. Oh well. frown.gif

Here is a picture of it. Otherwise, screen is awesome! My EVGA 970 GTX with everything on High in BOPs 3 has no issues running at 90 fps with this monitor and the 2nd one on the side.
