Would You Worry?

If you were going to buy a QA-2500 from someone and they told you:

I have checked the panel, it does have an S-video
Input and the input is working. The image looks good,
However there is one single pixel drop out. It is about
An inch away from the edge of the image on the right side in
The middle. It is one small dot (individual pixel) that shows
Up as blue on a black background. Other than that, the panel
Looks good and works well.


Would you worry?
 
Yeah but that's the thing, I did already buy it, lol.

It should be here on Thursday. I bought it from a surplus company. The guy told me that this only happened when he used the S-Video input, he said the composite worked without the one pixel loss.

I'm all for getting the best, I agree with you on that. The QA-2500 is definitely the best and they are extremely rare so I figured that a blue dot on a black background should'nt be too big of a problem since I'm only going to be using it for video games, NFL Football games and maybe a movie here and there. I thought hey, how many pure black backgrounds am I going to get with that routine?

So ham, my only other question would be, is what he told me a deal breaker or is it something that would'nt bother you much?

I mean it's a QA-2500 and I only paid $175 dollars for it and that's with remote, cables and the original case...........

I'm interested to know what everybody here thinks about this, I would appreciate some feedback.
 
one lonely pixel? just one? i wouldnt worry about it. most projectors, panels, and lcd monitos have stuck pixel(s)... so its not uncommon.

however, you state that he said it only happens when s-video is used and not with vga, this might mean it has a hardware issue/bad board(s) or maybe he was using a bad s-video cable. maybe tapping the panel can unstick the pixel, wiggle the wires and ribbon cables to re-seat them. that "can" sometimes fix some of these problems. remember that most people wont notice a stuck pixel expecially one off to the side, thats just us that are so anal about image quality/size/performance.


to get the very best you have to pay for it out of your (_._) and for $175.00 i dont think its a deal breaker. if anything, toss it on ebay and just state that you used it with the vga and not s-video so you werent aware of the "problem"

goodluck

apothesis, i liked the "chuck it on ebay", so honest...

but I have to say, I would 2nd his thoughts that it might be a problem with one part of the panel, and it may lead to more or maybe its just a loose component, I get that with tv tuners for some funny reason, ah well.

But yeah, its a steal at $175, and if it turns out to be bust, and you don't happen to have a conscience, then chuck it on ebay, and make a profit.

good luck , and let us know how you get on with it. By the way, what did it replace, in the way of your old projection panel.
 
Actually ham_anegg, this is my first projection panel.

I'll be sure to let everyone know how everything turned out.

I'm still just trying to weigh whether or not one small blue dot on a black background is really a big deal when there a very few times when you're going to have a pure black screen.....?

Could'nt I touch this up with a black felt tip pen?
 
Like I heard someone say above, one to three dead pixels are normal for LCDs. As for it being a problem with projection... You bet your *** it will!

If you do have a dead pixel on your LCD you better hope it's up in the border range of a widescreen movie or be prepared to go nuts every time you watch it!

Remember, one dead pixel isnt a problem with your using the LCD as a desktop monitor.... depending on where is is and what color it is you hardly notice it. But when you blow that picture up to nearly 10-20 times it's original size... that single pixel gets... HUGE!
 
Jcbklyny, I think your standards are way too high. One dead pixel isn't going to be THAT bad. Hell, I have a dead pixel towards the middle of my 640*480 panel and I hardly ever notice it. I mean, dead pixels may get in the way sometimes, but you make it sound as if a dead pixel on a projector makes it completly unusable.
 
neo851 , if all the dead pixels are on the borders you should make some kind of mask to block them from being projected to your screen. maybe even use black electrical tape... you will loose only a little of the image but in return you'll have a perfect image.

***UPDATE***

Just got my QA 2500 today.

WOW, this thing is sweet! It's got quite a few functions that big screen TV's have today most notably the picture freeze function.... Very cool.

Anyway, the Panel is in fabulous shape so far as I can see. I've been using the composite video input with my XBOX and I was playing the ESPN NFL Football demo (I'm a big Sega Football fan). It looked excellent considering that I was projecting onto a dull white wall.

I tried to make the room as dark as possible but there was still some light shing through the windows a bit.

There is also ALOT of light escaping from the insde of the projector. I'm going to build a case around it to trap it in, and build a light funnel around the lense to the LCD screen too.

I think that fact that:

1. There is alot of light escaping from the projector
2. There is still some light (only a little though) passing through my windows and curtains
3. I'm projecting on a dull white wall and not a well put together screen
4. I'm also using composite video and not S-Video

Is the reason why the image is pretty dull, washed out, and lacks sharpness and overall brightness. But, I could still see it well enough to play an entire game of the ESPN demo and be able to read some of the text, and keep in mind I'm still using that fried fresnel lense I was telling you guys about a few days ago, lol

I've got the new fresnel but I have'nt put it in the projector yet.

I'll keep you posted on how the project turns out overall, but right now I am VERY, VERY pleased with what I am seeing and I can see the potential of where the overall project can end up!
