I know the differences between LCD and Plasma but what are the main advantages/disadvantages of DLP over LCD? I went into a high street shop the other day and saw sony 1080p 50"+ DLP for about £1500, that's almost a third of the price of the equivalent sony lcd! Had a contrast of 10,000 and response time of 2.5ms. Picture also looked very nice to running a blue ray demo. So how come DLP is so much cheaper than LCD and are they a better option of LCD?
Which is better LCD or DLP?

Rainbow effect is difficult to describe you need to see it for yourself, but on a single chip DLP projector (slow spinning) you might see a wash of colour, a bit like edges blurring between each other. It's hard to desbribe because it rarely shows itself, and it's over really quickly.
Screendoor is the spacing between pixels, LCD has a black grid where the gaps between the pixels are, but DLP pixels are closer together, thus elimating screen door effect.

Only if you buy a DLP that you don't see rainbow effect. 6 chips definietly won't have it, but they're quite expensive.
Best to have a demo yourself. Make sure the room is blacked out, don't view it in bright room. You can usually spot rainbow effect if you quickly look at different parts of the screen, or bob your head side to side. Once you spot it, you'll spot it all the time (if the PJ has it)

I have the Sony 55" Bravia SRXD RP 1080p set, its SRXD as opposed to DLP, so no rainbows - and an absolute steal for £999

Catch is having to replace bulbs like projectors and not really being suited for turning on and off a lot, oh and dimensions and weight I guess.

They obviously are deeper - i wouldnt say they are any heavier, i was easily able to lift my 55" onto the stand on my own - it was about the same weight as my 40" Bravia LCD (just obviously a bit tougher to manage on your own with the size).
The upsides and downsides -
upside - Better picture than either plasma or LCD, deeper richer blacks.
more bang for your buck.
downside: 8000 bulb life, bulb costing about 150 quid, however this is about 4-5 years of tv watching, when a new bulb is put in, tv looks as good as new (unlike plasmas and LCD which deteriorate over time).
Restricted viewing angle, as long as you sit roughly with your eyes in the middle the picture is fantastic, if you stand up the picture does not look good.
I have had 2 Plasmas and 2 LCD's in the past 5 months till i bought the SRXD 55 - this is the first set ive been happy with, the only downside is no 1080p on component and VGA is a bit screwey for xbox 360 (rendering it useless at the moment, hopefully a firmware upgrade will fix this). It blows the previous Bravia 40W i had out of the water in picture quality and overall viewing experience.
Does the pictures brightness fade at all as the bulbs come towards the end of there lifespan? If changing the bulbs is the only downside and considering they don't need changing that often I'm VERY temtped to go for DLP. And how exactly are they not suited to being turned on or off?

Yes they do, but so do the screens on LCD's and plasmas - however when you chuck a new bulb in, the set is back to as good as new.
Its not DLP you want, its SRXD you want - specifically the Sony Bravia SRXD 55"
You seriously wouldnt be disapointed with the set, i absolutely love mine, ive been through 5 tv's in 6 months trying to find a set that im happy with, and i now finally am - even SD stuff looks better on it that on my previous panasonic 42" Plasma and Sony 1080p 40" LCD.
I've had a DLP projector for about 2 years and initially I couldn't see the rainbow thing until I made the mistake of viewing the "THX Optimiser" that comes on some DVDs. I think it's the nature of the test patterns that increases the rainbow effect.
This really shows the effect up (for me at least) and after that I could see rainbows all the time! Over the months my susceptibility has decreased again and I hardly ever see one now.

I have the 50" Sony Bravia 3LCD Rear projection TV.
Absolutely lovely set, had it a year now and got it for £1100 with glass stand included. I have my PC hooked up to it via HDMI and play all my games at 1920X1080 and it looks fantastic. I dont watch TV, just DVD's and video games.
These sort of TV's arent really suited for short veiwing though. I would never turn it on for 10 minutes to watch the news before work for example.
For me at the time the choice was 40"LCD or 50" DLP for less money. If you have the space then DLP for the win.
