LCD is replacing CRT. This happens in my company also. My company has been buying LCD monitors to replace the CRT monitors, in stages. When old CRT dies, we replace it with an LCD. No problem there. Problem arises one or two years afterwards. The LCD monitors started to die off. Actually, it's not the LCD that conked. It's the fluorescence tube behind the LCD that quit working. When we were using CRTs, it normally lasted 5 to 7 years before it gives us problem. Now with LCD monitors, the attrition rate is just too high ! I mean, after a year or two and many started to drop like flies. It's getting to the point that it ain't funny anymore. With CRT monitor, if there is any problem, most of the time we can get someone to repair it. With LCD monitor, once the fluorescence tube refuses to shine anymore, there is no way to replace it. The damn thing is fused/glued together at the back of the LCD panel in such a way that it is next to impossible to remove/replace the tube. Even if we can remove the fluorescence tube, we can't find anyone who sells a new tube ! So it's a total write-off. No remedy. No nothing. Nada. Of course we are replacing the dead LCD monitors with new LCD monitors, but I need help. I've read somewhere that some new LCD monitors got their back-lighting from LED arrays, rather than the useless fluorescence tube, and the one uses LED arrays can last longer. The thing is, when we go to buy LCD monitors, often there is no indication which brand / model uses the fluorescence tube, and which brand / model uses LED arrays. I've also heard that many manufacturers outsource their LCD monitor production to companies in China or India, and there are LCD monitors with the exact brand and model, a batch may comes with LED array backlighting, but another batch, perhaps from another plant, comes with fluorescence tube. Therefore, my question to all of you is this: How do I know **FOR SURE** which brand and/or which model of LCD monitors are equipped with LED array backlighting ? Thank you !

The fluorescent tubes can be replaced, I've done it on a number of LCD monitors. It's no walk in the park, but it's far from impossible. Yes some now have LED backlights, though high brightness LEDs don't last forever either and it remains to be seen how well they hold up in this application. LED backlight technology is relatively new, if a monitor uses it, it will probably say so prominently. Another option is to buy CRT monitors, they're a dime a dozen, I wouldn't trade mine for anything.

I just got an LCD monitor that I had hoped would last 5 yrs or more. I don't know if this will help but you can search the FCC numbers, you can get who built it and more info than the specs. https://www.part68.org/tteSearch.aspx or https://fjallfoss.fcc.gov/oetcf/eas/reports/GenericSearch.cfm A very good FCC search was www.part68.org/tte.cfm but it's 404 now

If you go with the big name brand names in monitors, you will get LCD monitors that will last a long time. We are buying the Viewsonic and NEC professional series. Most of them are lasting about 4 to 5 years. After they wear out, we replace them. We started buying them about 7 years ago when they were very expensive. The payoff was very good from these. With the LCD monitors our clients found that employees complained much less about the strain of working for long periods in front of the computers. The amount of sick days went down. There was also some savings on power usage. There is a huge savings on useable desk space. The LED backed LCD monitors are much more expensive. It will be indicated on the monitor or in its spec sheet if it is LED backed. Apparently, the LED ones have their problems, because these LED's are working at very high intensity. As for replacing the backplane lamps on LCD monitors, on some models this is possible. But, it is time and work intensive. You will also have to research what type to buy and where to buy them from for the model type that you have. The monitor manufactures will only sell service parts to their authorized service reps.

LED backlight technology is relatively new, if a monitor uses it, it will probably say so prominently. Another option is to buy CRT monitors, they're a dime a dozen, I wouldn't trade mine for anything. With 10 to 20 dead LCD monitors a week, of different brand / model, there is just no way we can pry open all of them, get the darn fluorescent tube out, look up a supplier online (seems that only the online suppliers sell the tubes), go buy from the supplier, and try putting the damn skinny tube back into that little space. No way. It's just no f*cking way ! And the darnest thing is that the LCD monitors all use DIFFERENT & INCOMPATIBLE TYPES of the fluorescent tube ! Why can't they just unify the design into one-single-type-of-fluorescent-tube so that people at least can buy the thing anywhere, and replace them when necessary? Can you imagine if the fluorescent lamp to light our house are of many different and incompatible size / _style_ / power-grading? Would you even use the fluorescent lamp in the first place ?? Why can't they just standardize that damn fluorescent tube they put at the back of the LCD monitors? That's why our warehouse is piling up with dead LCDs, almost brand new (the most 2 year old). Nowadays people are talking about GREEN STUFFS and everyday I look at the pile of dead LCD, I dunno if I would laugh or cry. They say CRT is poisonous. They say CRT ain't GREEN because it has lots of lead. Yet, CRT last up to 9 years, and in most cases, they can be repaired with ease. In other words, CRT is actually MORE green than the LCD.

The thing is, when we go to buy LCD monitors, often there is no indication which brand / model uses the fluorescence tube, and which brand / model uses LED arrays. There is an off the wall way to be offered only LED LCD monitors. The mercury in fluorescence tube are a hazardous material, you can you can turn green and demand only LED LCD monitors. Or require a MSDS for each monitor MSDS for Mercury https://fscimage.fishersci.com/msds/96252.htm I know it's off the wall.
