NEC LCD2690

Meow,

If you are about to repair the display yourself, could you inform us how it went and how it is done? If you get the schematics from NEC, could you post them for us also? And maybe a photo of the part that needs to be replaced? :)

I can hold a soldering iron, but I'm not very good at locating problems... :(

Not that I'd even own the specific display yet, but if this problem isn't repairable, I will not buy this display. Just have to wait more if someone else would create a better display... I've heard some rumors that there would be a next generation of Apple Cinemas in the near future... but they're just rumors... :(

Anyway, thanks for any help you can provide!

DAMN!!! I just send back mine cause had 3 stuck pixels. Now I will get new one and probably will have problems with this noise!!! I'm gonna shoot myself for buying this junk!!! Too bad shop where I bought it doesn't have return policy and only they will change for new one if it has dead or stuck pixels. I should get EIZO. :(
 
lukx,

That's pretty good shop if it will change the display for 3 stuck pixels! Most of the shops are not willing to do that!

...and not even Eizo gives a "zero faulty pixels warranty". It has the same standard as NEC. That sucks, huh...
 
well, they have same pixel policy but with EIZO it's very rare to get panel with pixels, plus I heard that EIZO is using better panels then NEC etc.(yes in some moedls they using PVA but still they're choosing better quality ones - this is also why their more expensive).
 
That Eizo uses better panels then this NEC is a myth IMO. NEC uses only grade A panels: http://www.necdisplay.com/protectyourimage/quality.htm

Eizo also uses S-PVA and TN panels in some of their screens (not in their highend models like the CG series and the Radiforce series). If you browse a bit in this forum, you can read a bit upon the Eizo CE240W (S-PVA) and others including the NEC:

This in particular when it comes to a common issue with the CE series:

Since I did not get a call from NEC Support on Friday I called again today (Monday) and they told me again, that they never heard about this problem before. At least this time they gave me a RMA number. The problem is, that they would replace the monitor only, if a technician would come to the conclusion, that the noise is too loud. NEC Support agreed, that is is a very subjective problem. So I called the store where I got the screen from to give it back and was told, that all big screens have a high noise level. So, I really don't know what to do now, except starting to use my old CRT again.

I think the store brushed you off. Noise problems like this have been reported with a lot of screens. Dell 2405WFP, 2407WFP, 3007WFP and also other models from other companies. So its true that you can get screens with noise, but also those without noise at all. Including 2405WFP, 2407WFP, 3007WFP. My f2304 have no noise at all, but chances are that there are some out there with such noises. Make a search of a model and include high pitched noise like this:
http://www.google.no/search?hl=no&q=2407wfp+high+pitched+noise&btnG=Søk&meta=

My 2690 do have a high pitched noise with a steady buzz, but only when I put my ears into the vent on the sides or on the back. I can't hear it from front even if I put my ear into the screen. Seems like its directional, not widespread. I'm no sound engineer though, but I have unfortunately inherited migrene from my mother, so if this sound were heard from my usage distance, I'd probably lay sick already.

I don't doubt that there are NECs with sound much louder then mine (especially if you look at the search above), but there are also those without that sound. If NEC haven't heard about these issues, it could be a good sign as well. Looking at how hard it is to get one of these babies, they must have sold a lot already.

I would return it and get another if you like the screen besides sound, or get a refund if you didn't. This is a defect, not how LCD's are in general! :)
 
concerning the noise issue - I have noticed that my 2690 shows a frequency of 59.9 Hz when it is running at max resolution.

Is it normal? I found reports that the noise from monitors may be due to wrong refresh rates.

Can anyone confirm that the monitor is running @ 1920x1200x60 Hz exactly?
 
Mine have H 74kHz and V 59.9 Hz @ 1920x1200. Sound only noticable from behind with ear close to back or sidevents. No sound from front.

Edit: I just ran 1400x1050 @ 74.998Hz and sound is still there
 
I will be forwarding all of the information from this thread on to NEC Europe so hopefully they can look into the issue. Unfortunately since none of noise reports are from the US there really is nothing I can do and hopefully it was just a bad batch of units.
 
I dont' think it's only a big lcd problem, my Sony 15" crt make the high nois too, but instead my Flatron 17" is silent.

Thanks for doing this. Will NEC Europe report back to you? If not, how will we know what conclusions NEC engineers came to? It would be great if you were able to post here whatever they tell you about this problem - or at least their policy on it. We need a consolidated view - otherwise NEC will just deal with this on a case to case basis.

Thanks

Mine 2690 run also on 59.9 on the 8800 by 1920X1200 and absolutely no noise.

so the question is: did you buy your screen in europe?
by the way, the noise is clearly audible, even if you just enter the osm having the PC turned off...

This evening I took the display to the repair shop in Moscow. They didn't check it in my presence and they told me that the answer will be in max. 3 weeks.

Even if it will be repaired or changed, I will keep my old 18" IPS LG as a backup.
 
Not that this is much help since you guys are in Europe, and I'm in the States, but when my NEC 2070NX developed a buzzing sound I called NEC support and they shipped out a replacement monitor right away. They didn't qualify it by saying that a tech had to look at it first, so I'm surprised that they would say that in Europe. My experience with customer support was great, although tech support left a bit to be desired since it took 4 tries until I got a good monitor, which included a couple of screens supposedly refurbished to factory specs.
 
For all those wanting answers about noise i'm afraid i can't help, but i have been on to NEC about spectraview software. This really applies to us Europeans, as we can't download the software as it only ships with the SV 2690. However they did give me a link to a spectraview profiler which, correct me if i'm wrong, can be used with, and supports many colorimeter and spectro-photometer sensors all of which are capable of, while using the given software, adjusting and calibrating the monitors 12bit LUT, in fact the software can calibrate upto 16bit. Once you register you can download a trial version. As i don't currently have a senor i was hoping someone could check out the software and see if; 1) its any good, and 2) if it requires the sensor for all adjustments?

The link is below, click on the 'Download Area' on the right in the blue bar.

What is the physical measurements of the LCD, ie actual screen size and footprint? I'm trying to figure out how much of a screen size increase I'll have coming from a NEC FP912SB and if it's even possible to place the 2690WUXi on my desk with the a NEC CRTs flanking each side.
 
So the noise issue seems to be only affecting the European models? Bad transformers that chatter too much?

I've been holding off buying this monitor because of the noise complaints, but if the North America models are clear of these issues, then I may just give it a try and buy one and hope for the best.

Travbomb, do you know of any complaints coming to the North America NEC division directly? I also asked in a previous post, but you may have missed it: If I order the SV version, would you have an approximate turn around time is to get the monitor delivered to my door?

Software is in stock so it should not be any longer then if you ordered it from any where else. Just try and get a drop ship from our warehouse.

I have not heard of a case of the noise in North America to this point. When i brought it up to our technical support and engineering they said they had heard nothing either.

Generally service in Europe simply isn't at the same level as it is in the US. Cross shipping is basically unheard of. This is regardless of manufacturer or product.

The explanation is simple - in Europe we have 220 volts, 50 Hz
In the US - 120 volts, 60 Hz

Different voltage and frequency means a different circuitry in US models.
 
Hmm, since I'm in Canada and so far no reports of noise in North America... I just may have to give this a shot. But if there's noise SOMEONE in US/Canada tech support is going to be hearing about it! :)

I don't think that the whole circuitry have to be changed. It's like with motherboards, graphic cards etc. You can buy them in usa and use in Europe. For things like monitor only psu for it will be different I think or even no difference like with PSU. You can use PSU from USA in Europ only different cable.

yes, you can do that, but only thanks to the PSU, which feeds them with 5V, 12V

with NEC displays the situation is different - the PSU is inside and it uses different circuitry for 120 or 220 volts, hence the noise. Maybe.
 
So, the company that took care of my monitor for NEC informed me today that they shipped it back to me. Eventually the power supply was (quote) loose and they had to solder some parts that connect it. After that the monitor wasn't audible from a normal seating distance anymore. I sure hope that is true. I will report back as soon as it gets here.

Looking forward to hearing your report - the "loose" power supply sounds unlikely. I dont think the high pitched tone is a mechanical thing - it's electronic. Anyway,...it'll be interesting to hear if you find any difference. Good luck!.

to travbomb:

What's your opinion on this series--the 26" or the 24"--on their viability as a TV display. If fed with a 1080p source--and 1080p source only--can it equal or surpass the video output of, say, a Sony or Sharp 1080p display?

I'm aiming for the 24" as a Mac monitor and as a TV/DVD/HD display. Your comment will be much welcomed and appreciated.
 
O.k., the monitor is back. The tech guy left some tiny scratch marks :)mad: ) but other than that everything is fine. The really disturbing noise is gone; there is a slight high frequency noise, but it is on an acceptable level, at least when sitting in front of it. When you get behind it, it's still very noticable. But I'm fine with this now.

No need to mention the great quality of the picture ;) I watched Open Season (blu-ray) on my PS3 and it is simply jaw-dropping!
I turned down brightness all the way to zero. Sharpness is at 28,6 and colorcomp is at 3. Auto brightness is turned off. I took down the black level to 114 for Open Season (to match the cinemascope to the black borders of the display. That worked just fine (I will do some more tweaking later).

After a really bad start I am happy with this monitor. It auto syncs neatly to my MAC, the PS3 and the Denon 2930, truthfully showing the current refresh rate (60Hz, 59,xxHz, 50Hz). I wonder what it will be like when the PS3 can output 24P.

On a side note: I use it for computer work but also for watching movies. If you watch alone I think this is as good for watching HD films as any Full HD TV (if not better, due to the 92% color space as oppose to 75% that most LCDs nowadays have). If 26'' is enough you won't be disappointed!
 
I'm not sure if that's good news for me. Seems like the noise of your monitor was also acceptable for the tech guys. Well my monitors noise can be heard sitting in front of it, and is more audible behind the screen as well, but it's not acceptable for me, it gives me a headache. I should get a RMA sticker the next days to have it picked up.

Absolutly no NOISE comming from my 2690, I asked a freind and he has no noise too.Purchased in Montreal, Canada.

I just check and those monitors are dual power. I would be curious to see if the monitors boughts in North America would make noise when powerd in europe?

Yes in Europe (The Netherlands), and these have absolutely no noise from parts inside the nec.

Thank you for the insights, HDJK. I'm sold then on the 24 incher. A TV and an Mac monitor in one display. That will be sweet.

I agree about this not necessarily being good news. For me, the high pitched tone is the irritating one and it's not clear to me that NEC will necessarily do anything about it; all they have to say is that it is within normal limits. Please post your experience of getting your display changed.

Thanks for the info. I actually downloaded their PDF spec guide and got the measurements there.

I placed my order at Provantage on Wednesday afternoon, and its expected to arrive tomorrow (Friday). That's some pretty quick shipping. Got a good deal too at $1480 shipped.
 
This is either a mistake or outrageous, I just checked the prices for both the US and UK prices for the 2690 spectraview and basic editions and this is what i found on the NEC sites:

US 2690 regular: $1699.99 (£878.265)
US 2690 Spectraview: $1999.99 (£1,032.59)

UK 2690 regular: £789.00 (£927 inc VAT)
UK 2690 Spectraview: £1,149.00 ( £1350 inc VAT, excluding the colorimeter which is another £150, so in total its £1500)


The regular versions seem to actually match in price, however i dont see why the UK Spectraview is so expensive, especially that they skimped the £150 colorimeter that comes included in the US price, and instead you get a couple of cheap plastic plates as hoods, you get charged %50, that is £500 more. This really isnt fair at all... I hope that they realize that this just simply isnt acceptable.
