Above, is one of my two 17″ LCD’s made by Dell, and below is my second:
I wanted to show you guys these monitors because I’ve been using them since the 2006/2007 mark. That’s like 6-7 years. These are just the basic 17″ LCD’s you can buy for around $100 now. That’s what their prices were back then. You can usually expect them to last a long time
I remember I found a site that can look up the parts that are used in monitors of cheaper brands like Dell, Acer and so on. I looked these monitors up and there was LG parts inside, I was actually amazed. I cannot find that URL to where I looked them up, but basically it requested my Dell LCD’s manufacturing number and after entering it I got the scoop of what’s inside.
The science behind it all
The CCFL or Lamp inside the LCD monitor slowly degrades with time. Some say that the end of the life of the LCD monitor is when the Lamp gets to 50″ of it’s output lifespan, though I am not sure how you can keep track of the output percentage. Let’s just say, when your monitor is showing green lines or just going green in paticular, that is a sign that it’s nearly dead.
Most backlights for LCD screens are also either cold cathode fluorescent tubes, or garden variety fluroescent tubes. The LED’s are are usually rarely ever used (except for cell phones), which is due to their unbalanced emission spectra. Though the tubes in LCD’s do eventually degrade alot like LED’s though unlike LED’s they sometimes do just die out.
The lower output of your monitor when you are using it, as in the brightness and everything else that makes it very bright and crisp, the longer it will last. I have been using these Dell monitors long enough that the whole time in that 6-7 years, I have always just left them on standby, without turning them off, and that hasn’t decreased the lifetime by much, judging at how long it’s been so far. But once in awhile, I do shut them off.
I also owned a Samsung SyncMaster 2493HM for almost 2 1/2 years, as it was previously owned by my brother in law. This is what it looks like, but that’s not my exact monitor, same model yes. It was able to move in any direction, so from this point where it sits here in the image, I could lift it up, just by using my hands to push it up. Then I could swivel the monitor to it’s side, again by just lightly pushing the LCD to it’s side. This is an LED backlit monitor.
Anyways, the lifespan of this monitor ended about 3 weeks ago. But I think that the display itself is fine, it’s just the wiring inside the monitor that caused to screw up because of the complicated technology behind the swivel design. I used the swivel thing alot, and I also moved it around alot too.
By the time I called Samsung to ask if it was still under warranty (without knowing the actual purchase date), they obviously said it was out of warranty. It only comes with a year warranty. And Samsung said they would fix it for $120, but I noticed 20″ monitors online for $150, so I decided that it wasn’t worth it. For so long, I had this setup:
And that was, awesome. I wish I still had this setup. But anyways, I think the issue with this monitor was like I said, something to do with the swivel, which screwed it up in the long term. It seems to be a power supply issue. I found a video on Youtube that explains on how to replace it, check it out below if you want. I may actually use this tutorial eventually too.
But anyways I also read somewhere that the average lifespan of an LCD monitor is 60,000 hours. I use mine for around 1-3 hours a day. So I will just put onto a calculator, 2 hours x 7 years = 5110 hours. I can’t believe that’s so low. Well, I hope my Dell monitors last around 60,000 hours. At one point I did notice that my silver Dell 17″ LCD kind of was going green before at some point in time, then it went back. I don’t know if the monitor *decided* to keep working but, thanks Dell for implementing that feature if it is a feature that you guys implemented. If your looking for a cheap LCD monitor, go with Dell for sure!.
