CMV 1515 in Disguise? I can't tell...

Wow, very cool. I was waiting to see that NEC - does look rather dim though (both 15's) Hard to tell just by the pics how good/bad it is. Good to hear dissassembly wasn't too bad. I'm still struggling with the flex cables on my 152T - but I'm making progress. So you say the colours are the best on the CC1512 out of the four? Definately not bad for the price, my 152T was 440CAD after tax etc.

However the specs mystery still seems to be present 🙁

Fine job 18Wheeler...very nice! I would be on my over to Circuit City now except for the 9" of snow outside! When I do get out I'm going to buy one... the price is right, the image looks good.

I don't know how well I'll handle the strip down since I am the only man alive with 10 thumbs. No....really...don't laugh... I have documentation...10 thumbs!

When you said "a little tricky" I got scared. I'm using an enclosure, so I'll be able to use this LCD. I'm still a bit in-love with the BenQ 567s... it has 400:1 contrast ratio. Maybe the snow is a good thing...give me time to clear my head....hmmm.

I was thinking about your question whether you should keep it or not... well to me it looks good, stripped down relatively easy and the price is right. I would say keep it. I guess what really interested me was the contrast ratio. I seem to be hooked on the fact the hight the CR the better the image.

I really got some good info on your comparison shots, that was very helpful. If you find the CR is 300 or less... would you still want it?

Have you seen or have a BenQ 567s? How do you think it compares to that one? (self-serving question on my part). The best price I've found so far on the BenQ is $276 and that includes shipping. This one is $239 after rebate, even with a 5% sales tax I'll make out better price-wise. I do like that BenQ 567s though... what to do...what to do?

CMV1515 is better one if you have to keep the LCD in 90 degrees angle. If you use BenQ567s same way the light distribution is uneven and the contrast about 280:1. However, if you tilt the LCD about 12 degrees the contrast ratio of BenQ LCD will be 450:1 which is much better. Also with BenQ LCD you have to use split fresnel (two fresnels with the LCD in between).
 
Here are some pictures. They may help you to take the lcd apart

First you need to remove the base:
An externally hosted image should be here but it was not working when we last tested it.


use a flat screwdriver to pry out the cover. Then unscrew it.

Once you done that, you will see a single screw at the bottom. take it out and push the back cover upward. it should open. you may need that flat screw driver to loose it up.

An externally hosted image should be here but it was not working when we last tested it.


once back cover is off, you need to unscrew 4 screws which keep the front cover on; and the smaller screws that keep those side metal pieces. now those wires should be exposed.

An externally hosted image should be here but it was not working when we last tested it.


My camera's battery died after these shot. so:

after remove the metal piece on the top, there is another screw to keep the PCB board on frame. take it out.

unplug all the wires from the PCB board.

don't need try to remove the big gray metal piece. (I didn't realize that UNTIL spent an hour and removed it 🙁, I can tell you what inside: 3 U shape lamps in the light chamber)

turn the monitor over. There should be 4 screw at each corner. Now remove them and carefully remove the screen.

If you are going to use it on OHP, flip the lcd and put back to the original metal front bezel. dont forget to use a strip of tape to insulate the bezel.

I might skipped a couple of screws when I am telling the story. So whenever you cannot remove one of those pieces, stop and check if any screw is in the way. If you broke any piece during the process, put everything back together, walk back to CC and make sure you look totally innocent 😀

Get some batteries 🙂 I'm buying this one tomorrow! I'm building an enclosure and it sounds like this will work for an enclosure as well as OHP. Thanks for your help in making my decision... well Ace also encourged me to get this one as well.

Hi 18Wheeler:

"funny thing is I cannot find contrast ratio stated anywhere. not on the box. not on the manual. not on the CD either. "

yep

that's a 1512 alright...grab it up kids, it's a good one.

Oh yeah 18 wheeler...you say it's darker, dumb question but did you check the brightness and contrast settings on the panel? They love to revert to their defaults for some reason....they should obviously be cranked all the way up.
 
This is for CMV1512. But we don't know for sure if NEG A150X1 is the same as CMV1512, although I suspect so.

By the way, anyone want to buy this A150X1 from circuitcity and take advantage of the $70 rebate, you can buy it online and select in-store pickup. the rebate offer ends tonight.
 
another LCD also has the same lable:
polyview A150X1 518A

An externally hosted image should be here but it was not working when we last tested it.


This is the contact info I got for the company selling NEG A150X1. Note the type of businessis DISTRIBUTION. Anyone can call them to ask what the original model is. and perhaps the detail specs.

Circuit City NEG A150X1

My Circuit City NEG A150X1 arrived yesterday, and 18wheeler was correct, the depth of color is pretty amazing. I'll probably strip it down over the weekend, and if lucky I'll post some pictures of my progress...and hopefully the football game on Sunday.
 
Found UK source of 1512!!

Hi,

I've just been to a shop in the UK called the computerShop
on they have a no name monitor there that is made by chei mie looks like a 1512.

The the sticker is the same as the circuit city one.

The guy was saying that it needed a Digital connector? sounds odd

Does the 1512 need a digital connector or was he talking bo********s?


THanks
 
Re: Found UK source of 1512!!

I don't know why he said that to you. He probably meant that the A150X1 does not have a digital (DVI) input, but has only an analog (regular VGA) input.
