LCD Projector Repair
The sum total of the individual internal components of LCD projectors is more than that of DLP projectors. The propensity of an LCD machine failing is therefore higher, Also when any of the components fails; they are always costlier to replace.
One of the known issues of LCD projector is manifested as what is called; ‘Chicken Wire Effect’. This shows up noticeably on projected images in the form of grid type pixel patterns making the image appear pixelated.
Other issue is overheating. LCD projectors heat up fast. As such the fans are more powerful and they work harder to cool down the unit, hence LCD machines tend to be noisier than a DLP projector.
Still, another issue is dead pixels. These are pixels that have stopped functioning and their state is either permanently on or off. The resulting effect is the appearance of black, white or coloured spots. In isolated cases, it may be tolerable, but when they appear in clusters, the effect could be annoying.
The bright side to LCD machines are the following;
All electrical devices, projectors included, are being redesigned with the goal of reducing their impact on the depletion of the ozone layer. Hence the less the energy used for the same level of output, the better. Here LCD technology takes the lead over DLP technologies. Both consumers and businesses take this into consideration when buying a new projector

Better brightness levels LCD projectors produces brighter images, compared with a DLP projector when using lamps with the same power rating. Projected images of an LCD projector have greater saturation. this is to say that the images are brighter, more alive
-
Rainbow effect is noticeable when bright objects are shown on dark background. Image appears to have trails of multi-coloured lights. Not everyone gets bothered by this phenomenon as most people do not notice
