When looking at a projected image, if you see an unusual amount of yellow or greenish hues in the image on the screen, chances are, you're seeing Colour Decay.

Many LCD projectors can suffer from Colour Decay after extended periods of usage. DLP projectors on the other hand, have a technological advantage of guarding against Colour Decay after extended use.

Colour Decay may manifest itself on many LCD projectors after an extended period of usage (eg: 2,500-4,000 hours of on-time operation). Many manufacturers of LCD projectors limit warranty coverage between 2,000 and 3,000 hours of on-time operation (or 2 to 3 years whichever comes first).

Maintenance calculations are based on estimated parts costs, labour costs, and recommended replacement periods. DLP® projectors enable sealed optics which do not require filters.

DLP® models without filters will have "Filter-free" listed under filter replacement and cleaning fields.

Aside from "Filter-free" DLP® models, all other maintenance costs can be manually changed by typing new values in the relevant input box.

Projector filters typically cost between €5-15 depending on the brand and model.

Labour costs can range between €15-30 per hour for in-house labour and between €30-90 per hour for outsourced labour.

Empfohlener Filterwechsel (Std.) In vielen Anwenderhandbüchern für Projektoren wird empfohlen, den Filter immer dann zu ersetzen, wenn die Lampe ausgetauscht wird. In diesem Fall würde die Filterverwendungszeit im Durchschnitt zwischen 2000 und 4000 Stunden liegen.

Typical labour costs can be €15-30/hr for in-house labour to €30-90/hr for outsourced labour for filter cleaning.

Manufacturer's recommended Filter Cleaning interval (hrs) Many manufacturers recommend filter cleanings to be done every 100 hours of on time or as needed (roughly 1x a month).
