Advice/suggestions on a "dead" Samsung 2693HM
Hi there,
New member doing some research into an issue with a Samsung 2693HM that I was gifted earlier today. I'm not an electronics expert or tech, just what you might consider an average Joe to some degree that's been mucking around with consumer electronics for decades. Having said that, I'll cut to the chase:
I did several hours of research on the specific problem I'm having with this 2693HM and it seems like most owners either had the "2 seconds to black" issue or the white screen issue; I haven't noted many that stated they had or have the same issue that I do so here's what's happening.
- Monitor appears to turn on when the power switch in the rear is set to On, blue power light on the front, no noise heard, no backlight "flash" of any kind, shining a flashlight onto the screen at various angles shows nothing at all
- Front panel on/off responds to touch and turns off the display one time - if I tap it again a few moments later it'll come back on but will never turn off again regardless of the number of presses/taps/touches, I have to do a full power reset with the physical switch in the rear to get that response again
- Audio subsystem is working to a point. When I plug in some source material I can hear it somewhat clearly through the speakers in the 2693HM, sad as they are. The front panel volume controls have no effect (unless I'm using them in an incorrect manner, that is
- When a VGA cable is attached to my laptop Windows will offer the "dunk dunk" sound of a device being attached, the display on the laptop kicks out to a 1024x768 resolution until I go in and alter the settings to "Extend the desktop across these displays" at which point the laptop screen returns to native resolution (1280x800) but still nothing from the 2693HM - Windows sees a monitor attached but I'm guessing that's just the sense pin on the VGA cable providing the "Hey, I'm plugged in now..." response
- Monitor doesn't seem to get warm at all no matter how long I leave it on (2 hours was the max so far, no sense in wasting more electricity)
- I disassembled it completely a short time ago and noted absolutely nothing that would indicate a problem: the power board, logic board, t-con, and inverter board all look just fine to my untrained eyes save for a tiny bit of dust buildup in various nooks and crannies
- The 2200uf 10V capacitor "looks" ok; no signs of bad caps or anything about to explode, and other capacitors look fine as well
- Put everything back together making sure to get a good proper tight fit with every connector in use but of course the situation hasn't improved (at least this time, sometimes in the past I've disassembled devices and after a rebuild they work, as odd as that is when it happens)
Now, as I stated I'm no board level or even higher level technician, I don't own a multimeter or most any of the other tools the pros use so I can't diagnose this thing any more than I already have. I figured because the power light is coming on and the audio circuit appears to be working that the power supply board is "ok" but of course I can't know just what's going on - it powers up, the audio is functional (but I can't alter the volume from the front panel controls as stated), and I'm not sure where to go from here.
I did more research before making this post and I'm just stumped. What I'd like to ask is if anyone has any advice or suggestions at this point on how to proceed - if I need to get a replacement board or two (even not knowing how something died in the first place) that's fine, I can install those without issues which is easy enough. Unfortunately I don't know precisely which one(s) to get.
Don't want to wear out my welcome with a crazy long post so I'll end this one and hope someone - anyone, actually - may have something to offer. It seems to be a great monitor, plenty of resolution (1920x1200 is my fave, 16:10 aspect ratio displays are a dying breed so this one is a keeper), speakers (don't need them but they can't hurt for some purposes), and so on.
If I can get it fixed without spending as much as a new monitor, preferably nowhere near that kind of pricing (even though I can find 20+ inch "HD" monitors for $100 these days). I'll consider this a project to see what can and will happen. I know I haven't provided the nitty gritty diagnostic info that could possibly help me, so I hope what I have provided might set me on the right course.
Thanks, and have fun, always...

Go figure. I've had it on and off all day, and it was just left on for a bit while I made this post. I make the post, turn around in my chair, reach over and turn the 2693HM off with the rear power switch and... for a 1/10th of a second I had a white screen with some other content - it wasn't a pure white complete edge to edge image, there was something else there as well. I nearly fell out of my chair when it happened.
Anyway, one last tidbit I just also discovered: the previous owner had apparently contacted Samsung at one point (he's the second owner) and stated - in a chat with their support personnel - that if he left it on for several hours it would just start working, and it would keep working until he turned it off (didn't specify front panel or the rear switch in that statement) at which point he'd have to leave it sitting for hours till it started working again.
How very odd... :p

After doing this power on - power off thing for a few minutes, it's almost like it's really trying hard to get an image displayed but it's incredibly faint when it happens, I'd describe it like someone lowering the brightness and contrast as far as possible so it's really really barely visible at all, and then wave a flag in front of it back and forth - seriously, it's this weird wavy moment where it starts to brighten just enough to know there's something there then it goes black, a 1/10 of a second later it starts again, etc, like a flicker almost.
Hey, it's progress.
psss (last one, I swear)
The monitor is "working" at this point. It went from an almost strobe-like pattern every few tenths of a second to staying on for a half second at a time, then a second, 2, 5, 10, 30, and now it's been solid for minutes. Haven't hooked it back to the laptop just yet but it is pretty crazy how it basically almost seemed to be fighting its way back to life.
I'm still interested in whatever opinions others may have, however, as I'm sure that I can't just leave it on 24/7 no matter how much I might like to do it - turning it off might "kill it forever..."
