help!!! keep destroying ceiling mount projector

forknuggler · 02-05-2007, 12:43 PM

Im using a sony vplhs-60 lcd projector, a yamaha htr6090 receiver, and xbox 360 hd dvd drive. The xbox is connected to the receiver with component inputs and then to the projector through the hdmi input. After about 3 days using this set up i noticed a light purple blob the size of a baseball in the lower corner of the 96" screen. I tried cleaning the lens but it did nothing. no matter if you were playing a game or watching a movie it was always there, so i took it back and got another no more than 2 days later the new projector stopped displaying red and yellow colors. I decided to try to hook up the xbox straight into the component inputs on the back of the projector, thinking that there might be a problem with hdmi connection. It still wouldnt display red or yellow. So then i thought it must be the xbox. I hooked it up to my sony 42" lcd and there was no problem. So now i have returned another projector and am awaiting my 3rd in about a week.
Would the way i have this hooked up be damaging the projectors. I can't understand why it would but i am out of ideas. Is it possible this projector is crap. Ive had vplhs10 and vplhs20 and never had any problems
please help!!!!!!!!!!!!!!!!!!!

It's got nothing to do with your hookups. The first problem sounds like a dust blob on the inside of your projector. The second color problem may be the LCD panels. Are you against a DLP projector for some reason?

is there a dlp projector that is similar in performance and price. the sony claims to have a 10000:1 contrast ratio and is also very quiet

Jim Mcc · 02-05-2007, 08:43 PM

That 10,000:1 contrast ratio is a bunch of BS. What is your budget? Do you have any special problems like a low ceiling, etc?

i don't want to spend more than 2200.00. I have standard 8' ceilings.
I really appreciate the fact that your taking time to help me out.
Also would the sharp dt500 be comparable

It sounds like you've been getting bad samples - unless the entire product run is junk, but that seems a trifle unlikely. I've seen LCDs do the blob-thing before, but usually on the blue channel, though once it was magenta.

Loss of red is one thing; loss of yellow is something else. Are you sure that only reds and yellows were gone, and not reds and GREENs that make up yellow? But no, going blue-only is different...

Anyway, the first issue we usually see after a fair amount of time and is caused, in part, by heat on the optical block and damaging the LCDs themselves - but then we're doing architectural installations, where the projector'll be running 8-10 hours/day, non-stop, and it usually shows up somewhere between 1k and 5k hours - not, say, 30!
