hi folks,just a quick,probably daft question.I was wondering if the nec multisync 1510+ is the same as 1510v+?? and if they are the same does anyone have the specs for this panel?,cheers lots Dunc_

Hey mate you would have thought so but it isn't

The NEC 1510 and 1510+ are hopeless for us guys, there are FFC cables all over the place! I think the + refers to 2 extra CCFL lamps (same in the V version).

Definately one to pass by, see if you can get a 1510V+, it's a great panel as the driver boards are very small and there's no messing around with FFC extensions, it will also work with that LCD panel i'm sending.

[dunc_42]

would the lcd from the 1510v work with the 1510+? just aquired a 1510+ working but loadsa dead pixels.cheers dunc_

I don't think it will, as far as i remember the 1510+ is totally different to the V version although it looks the same. Might be worth taking the back off and having a look at how it compares to the pics i've taken of the 1510V

hi,recieved the 1510+,stripped it and there isnt really any major ffc issues,there are two ffc connectors which are on different edges the offending ffc has around 10 tracks in it but i think 3 or 4 arent used,new soldering iron here we come! the main ffc splits into two connectors that go into the same socket,like a "Y" shape if you can picture it,i have taken photos of the strip if anyone wants to see?? The only lcd i have used to date is a psone and this one has a reflective coating on the rear like a mirror ,if you hold the rear next to a 60w bulb you can just make out a light in no more but cant see a thing if you turn the lcd aaround is it ment to be as dark as this? my psone you could see through it.
cheers dunc_

read a post on one of the american sites about this reflective layer and they took it off,who am i to be different,lol so i ripped it off too.it needed no soaking was able to pick the corners and peel,this took forever and it was reallllly well stuck and needed a great deal of force to remove which wasnt too handy but with a bit of persuading it eventually came off,the lcd is now bare with just the ag and polarizer left,the monitor when i got it had several lines of dead pixels,i have read somewhere about a possible cure for this but sounds sketchy,anyone any info on this? or where i can find a controller for 1510v lcd ?? cheers dunc_

not more crazy people ripping their panels apart!

On both of the NEC panels I've used in my PJ (including the one you've now got) i've had a single column of subpixels which decided to turn on all the time. I gently squeezed the flat connector with my fingers and found they went away, and in both cases worked indefinately, my current panel having done over 200 hours. Worth a try i suppose...

As for the NEC 1510V, you quite often get busted ones turning up on eBay. The people who are selling the power supply on eBay, on the link D2D posted up often get them in. Also look for the + model with smaller circuits..

hi,have seen a 1510 v+ reasonably cheep on e-bay but has no signs of life at all,the guy assures me that the psu works as he is using it to power another lcd,is there an on board fuse on these things and are the pcbs easy to work on the 1510v+(they dont look too crowded anyway),anyone know any other nec models that look do-able,dont mind extending a ffc as long as it aint millions of pins,the 1510 i have i was able to extend ffc but has that many dead pixels its like join the dots to get a picture!

[doug]

Alright Dunc, nice work with extending the FFC as i know that's a pretty hard job unless you buy parts.

I've had a NEC 1510V+ before which wouldn't turn on with a working PSU and there is an internal fuse but in my case it was working. The power distribution board is pretty simple, just a few transistors and capacitors but i destroyed it with my ham fisted attempt at replacing parts with a *quality* woolworths soldering iron i bought in a rush to fix it

Something was up with power not getting across the board, it looked like some sort of trigger wasn't turning on. Not impossible for someone with skills. In the end i got a new board and it fixed the problem Oh yeah it's all surface mount stuff but not crowded

[dunc_42]

got 1510v+ yesterday,was described in listing as totally dead,no signs of life,i was hoping it was a simple psu problem or internal fuse,i opened box(box looked like it had been used for a quick game of five aside curtosy of royal mail,lol. it said in listing not original stand,lol,the base was made of mdf and the upright was a chunk of 3x2 whitewood sprayed off white!!,lol.when i plugged it in with no signal instead of being dead the screen stayed blank and the backlight flashed on and off 6 or so times then went dead,after having a quick check of the lcd i seen someone had been there before me(i unscrewd the stand and the lcd fell into 3 parts ) but after changing the front switch panel for the one i got in the 1510+ i could get the orange/green led on front,tried it with pc but inveerter knackered,can only get picture for a few seconds before ccfl flash on and off then pic dissapears,but if i bring up lcd menu i can just make it out so its looking good for a 15 incher pj! yay!.

cheers dunc_

Yep! looks like you have a live, dead one there!
When i got mine, the inverter actually worked, but i ripped it out of there! ha ha ha!
Just be careful of the short ribbons, they unplug/unclip anyway.

This is how i started with my 1510v, (not sure if it was a + or not...)
Good luck!

chucked it together last night using the monitor front panel as a frame and used glue gun to hold pcb s in place while i tried it,worked first time,picture is huge,at not even half way across my living room the picture was about a foot wider than the opposite wall which is 15 feet!,was pretty good for brightness and fairly even although the corners werent brilliantly focused(dont notice with video just desktop/text etc),any tips on setting up the lcds own menu for a better pic? tried cars and into the blue on it,looks good to me,if a little on the huge side!

cheers,dunc_

Alright there Dunc! make sure that you have set the refresh rate to 75hz, as this gives a totally steady picture, 60 hz makes the picture flicker slightly, well, i say flicker, it just seems that it cant decide on which pixel to use when running at 60 hz.
75 hz is the native refresh rate for the LCD, so blah, blah, blah!
I could go on saying the same thing in many different ways! LOL
the only way to get a smaller image is to move yor PJ closer to the screen and re-focus it.
To get the corners better focused, you need to adjust the lamp/reflector height, and try to find the sweet spot where the focus is as even as you can get it.
