This question is interesting to me,hope u can give me an answer.

Im talking about Dlps or any rptv that the bulb can be change.

So what cause the PQ to go bad over time?

Does it range from color wheel, internal hardware or the display can be like renew in simply replacing the bulb?

For DLPs, changing the bulb when it burns out gives you a brand new PQ again. As with other technologies, parts can go bad but are fully replaceable, for example the light engine and color wheel, but there is nothing that degrades the PQ over time, unlike plasma that does eventually go bad is not not fixable (although not until after many, many years).
