The number of individual internal components of LCD projectors are more than that of DLP projectors. Consequently, failure of LCD machine tends to be more expensive to repair.
Issues affecting LCD projectors are;
- Chicken Wire Effect; This shows up noticeably on projected images in the form of grid type pixel patterns making the image appear pixelated.
- Burnt LCD Panels; This may result in pinkish, yellowish or bluish or a combination of any of these colors.
- Overheating; LCD projectors heat up fast. As such the fans are more powerful and they work harder to cool down the unit, hence fan failure.
- Ballast, main board and power board failure. All these are due to overheating.

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
