Put simply, the answer to this question is a resounding yes. The average age of an LCD monitor is about 12 to 13 years. Indeed many could last as long as a couple of decades if maintained and cared for well, (daily dusting for example). Until a major failure in the equipment happens; say from a transformer for example, minor components can be quite readily fixed and/or replaced. As a result, knowing how to repair LCD’s for yourself is quite a useful skill to learn, and pretty cost effective!
More than this however, most LCD monitors contain some pretty nasty chemicals and heavy metals. Extremely damaging the environment, the more we can cut down on releasing these into the world the better. And of course, the cost of responsible WEEE accredited disposal is in itself quite expensive – though many manufacturers are now helping with this, in return for you buying their latest piece of kit MaxiIM IM608.
Most commonly reported with a failing LCD, (once software failures have been ruled out), is dimming, or resolution fading. This is almost always indicative of a failing backlight, which can be replaced for around $20 quite readily. A simple procedure once you know where to put the screwdriver, the monitor can be back up and running in next to no time.
Next on the hit list for LCD problems centers, unsurprisingly, around the display itself. Whether this is regards burn out, (though quite extensive use is generally necessary for this to occur), or a simple scratch from a well aimed kids car being thrown! There are many tips you can learn to help repair minor scratches and scrapes – gentle application of petroleum jelly being one! However, split or severely cracked screens will need to be replaced.
Whilst it is possible to learn how to repair LCD screens, replacing one can still be very expensive, even if carried out by yourself. With all things considered, it could prove more cost effective to go for a whole new unit – but you may be able to get a deal, depending on the model.
Prevention being better than cure of course, there are a number of very good films that can be adhered to the screen before use. These can both help deter scratching, and improve picture quality by reducing glare. It is certainly something to consider.
