Back Projection and DLP (Digital Light Projection) screens.
I don't know what is going on, but I have had an influx of back projection and DLP screen repairs in the past 4 months. Although these rather large screens take up a lot of space, they can give a very nice picture once repaired and set up correctly. DLP screens use a different technology to the "old" back projection types and it is fair to say that they give a picture quality as good as if not better than their equivalent LCD and Plasma screens.At the heart of the DLP screen is a motor with a rotating coloured disk. This is called the DLP engine. This differs from the older style of back projection TV that used 3 CRT(Cathode Ray Tube) lamps that projected on to the back of the lenticular(screen). The main disadvantage of these screens were that they ran very hot and were very suceptable to poor convergence(colour separation) and resolution.
So if you have the space and don't want to take a trip down the dump in your neighbours "white van" then get it repaired and enjoy almost being at the cinema!!!
