Samsung NP780Z5E-S01UB Replacement Screen

I have recently got some image persistence on my screen, and have tried the methods of:

reinstalling graphics drivers
leaving it on a white screensaver for a few days
leaving it on a screensaver that cycles all colors all over the screen for a few days
high contrast mode for a few days
and off for a week

Nothing has permanently worked. I can reboot and it go away, but if I open and close a window it sticks.

I was wondering where the best place to buy a replacement LCD screen would be? IAnd would I need the digitizer and LCD or just one?

I am not going through Samsung because $400 is just too much for me at the moment.

Thanks

 

Somewhere like this might be able to help.

That is exactly the site I was looking at. But do you know if the NP780Z5E-S01UB has an IPS display or not? I know its glossy, but just not if it's IPS or not.

Also, do you know how well their screens hold up? Quality, etc?

 

NP780Z5E has an MVA panel, which is similar to IPS/PLS in terms of color and viewing angles (good) but also has the issues of some image retention (bad) which is not uncommon with IPS displays. I have a 23 inch external HP monitor with an excellent IPS panel, but it, too, suffers from some image retention. It is not a persistent retention, it goes away after awhile.

 

So the image retention eventually stops altogether? Mine stops after reboot but right after I open a window it happens again

Also, as per https://www.laptopscreen.com/English/model/Samsung/NP780Z5E-S01UB/ which setup would you reccommend? Glossy/IPS ; Glossy/NonIPS ; Matte/IPS ; Matte/NonIPS?

I am not a big hardware guy and not sure which I should get. Thanks a bunch!

 

No, it's inherent to the IPS/PLS/MVA technology (though I am sure some panels more than others). What I meant is it's not like it leaves a permanent ghost image, it goes away after displaying another image for a few minutes. A solid gray black normally does wonders for clearing my screen (my external IPS, I don't have an NP780).

There is much discussion about it in the NP770/780/870/880 Owners Lounge. If you Google site:notebookreview.com/samsung NP780Z5E image retention you should get lots of hits.

I am not a hardware expert myself, so I'll leave actual recommendations to John or others.

 

Glossy gives you more reflections than matte while I would assume that non-IPS is a simple TN panels with inferior viewing angles than IPS. As noted by Dannemand, "IPS" often gets used to include other technologies that give good viewing angles.

What is unclear in the listings is whether the glossy panels (which are more expensive) also include the touchscreen technology. Most touchscreens have a glass layer on the front to (i) protect the LCD panel and (ii) provide an easy to clean surface. I would suggest you contact the supplier to get clarification of these aspects.

I would also note that your notebook may use a glued bezel that may be difficult to remove without trashing it. I couldn't see any bezels or display panels listed for your model listed at Samsungparts.com. It is possible that the bezel for a different 15.6" model would fit if the overall notebook size is the same.

I presume your notebook is out of warranty. If not, people have had displays replaced due to the image retention issue.

Depends on your general usage:

• Movies/DTP indoors > Glossy, anything else indoors or outdoors > Matte
• If you want to keep the touchscreen > IPS (et al), don't care about touchscreen > IPS/TN

Now, do mind, what you're buying from laptopscreen is a compatible screen, not a specific screen. The one you actually receive could be any of these 14 models: Panel Specification Compare - Panelook.com (provided the connector's bottom-right).

The only limitation would be your choice out of those 4 main categories. Also, as mentioned before, choosing "IPS" is choosing a patented technology, limiting your choice to LG only (for a premium). Even though the AUO's use a similar technique, only marketed differently. If you don't care about screen quality/specifications then it's fine to take that gamble ... otherwise;

• Use hwinfo to find out your current model
• Filter list for glossy/matte (glare or antiglare on panelook)
• Search reviews based on the specific models and your current one

For instance, notebookcheck has done a review on the B156HAN01.2; apparently this happened to be in the Acer Aspire V3-573G that was tested. Remember that an otherwise completely identical Acer model might have had a different lcd inside, hence the importance to note the actual lcd model when testing/reviewing (not the system builder's part nr.). If not, it's apples and oranges. When you know your current model's values (brightness/distribution/black/contrast) you can compare those with the models available and you'll know beforehand what you can expect. You may still order from a 'compatible lcd' seller, but instead ask explicitly for the part nr. you want. If it's available they'll ship that.

One more thing; since you'll want to keep the digitizer (it alone is ~$200, after all, and certainly not included with a $100 lcd), make sure you're damn careful replacing that. Fragile, those things. If you haven't done this before; make sure to look at some videos before you start.

 

The screens do NOT have the touchscreen technology. The support guy said I would also need to put the digitizer on the new screen to have the touchscreen working. He also said it might not fit correctly without putting the digitizer on the new screen, since the bezel would be taking into account both.

I am not sure about the bezel either, but I will be having a Best Buy or other computer repair place doing the repairs, so it would be up to them to do it correctly.

Also, I am out of warranty as of march, and they quote me $400 to fix the thing, which is far too expensive.

 

So if I'm correct in understanding you, I definitely want IPS to keep my touchscreen, and probably Matte for best all around (mostly indoor, coding, movies) usage?

Also, I understand its a compatible screen, and not a specific one. As for the panellook, I'm not exactly following. I can receive one of 14 of the screens on panel look, and if I want IPS I would need to narrow down the specfications, and that would limit it to fewer than 14? I should then read reviews and decide which I want from there? But how would laptopscreen know exactly which one to give me? Not sure on the whole panellook park to be honest. Sorry for being a noob about it :\. Just an out of warranty not-so-hardware guy wanting the best experience for getting my screen replaced. If you could word it maybe differently or more stupid (lol) that'd be awesome.. Thanks

 

Yes, although strictly speaking there is only one non-IPS panel that would fit your system (this TN panel would give noticeable local brightening when using the touchscreen). Choosing "IPS" would disqualify the TN as an option, but also AUO as manufacturer since the term "IPS" is patented.

Depends on your lighting conditions. All things identical; office lighting, outdoors and desk lamps will give reflections, a matte finishing will prevent this (to some extent), but at the cost of less 'vivid' colors, which you'd notice mostly in movies. However, you're best off to simply use hwinfo to find out what type of screen you are currently using; under "Monitor". Chances are it's matte; if you'd go for glossy this time you'd probably notice reflections on the screen. If, however, your current screen is a glossy and you've never noticed the reflections (or aren't bothered by them) then you definitely do not want a matte; everything will seem 'washed-out' compared to your old glossy.

So, let's say you go for IPS&Matte; the 14 compatible options drops to 7 possible screens (since all the non-IPS's and glossies are no longer valid).

Now you could leave it at that and laptopscreen may ship any one of those 7. All these are still in production, so they'll supply whatever they have in stock atm. Yet, though compatible, they're not identical. The series numbers are LP156WF4-SP.. (where .. is different). Notebookcheck has done reviews for two of these:

LP156WF4-SPH1:


LP156WF4-SPB1:


Both are pretty damn good, but the H1 has 'deeper' blacks (and higher contrast) and the B1 has a far more uniform image and higher brightness. Actually, the distribution of the H1 is pretty poor (28% brighter top-right vs. bottom-left), might be a one-off though ...

But if you haven't got a preference then that's fine too, of course. Am a bit picky with these things myself ... but, again, both are pretty good screens, so changes are the other 5 in the series are all decent lcd's too.

Maybe an analogy is in order; you could ask for a 256Gb SSD and get one, but which brand/type/technology you'll get ... it's the same with lcd's (but with less competition).

 

So when I go to my shipping info,, I should tell them (going off what I've seen) to ship me the B1 LCD otherwise cancel my order. (the support guy said I could do that for specifics).

And it will work with my touchscreen as long as the replacement process doesnt break digitizer, correct?

 

Also my current screen model number is Monitor Hardware ID: Monitor\AUO9003

 

That's the same as reviewed by notebookcheck.

It might use AUO's MVA or AHVA technology which are their alternatives to IPS.

Moninfo should be able to identify the exact panel type. Look at the Data String in the Asset Information and compare to the list on AUO's website.

Notebookcheck claims it a TN, so the one they reviewed must've been the B156HTN03.5; it's the only 15.6" 1920x1080 TN at 300 cd/m².
A black value of 0.2 ... that's not something to sneeze at. Hence also the impressive contrast value vis-à-vis the IPS's tested before; your 'zero-point' is lower, so likewise a greater range; higher maximum contrast).

Viewing angles are not those of an IPS, but not as bad as earlier TN's ... so a great screen, really. If Moninfo says your screen is indeed this one then it's a bit unfortunate; image-wise it's fantastic, but image-persistance will also be an issue with a new one out of the same series. It is still a bit strange if yours is a TN (because of the local brightening issue when 'pushing'); does your screen have this effect or not? Also, do you see this 'image-persistance' all over the place or is it more pronounced in the areas that see more frequent touchscreen use?

Anyway, since it bothers you to the extent of replacing it; look for users of the other screens and check whether they have image-persistance on their screens after x-years of use. Trouble is that happy users tend not to post, whereas those with issues do.

Exactly, but if the repair service breaks it then it's their problem to get a replacement.

 

Well its only on the top and right of the screen. Id say its literally about 3/4 the address bar (right 3/4) and when I open a windows explorer window its the right side of the window outline on my right side of the screen. So in all its top and right, but not the whole window, just address and right outline when on the far right of my screen. And I rarely ever use my touch screen. Couple times a month. Its usually off. But if I am replacing the screen, I paid for touchscreen and I might as well make sure it'll work.

And I have only had the laptop for a year, which sucks that I'm already getting image persistence. Warranty ran out in march :\

Also, I'm not sure of the brightness issue when pushing is? Can you explain that to me?

And I'm not sure what's bad about the "TN" mode, not even sure what it is. But this one http://www.auo.com/?sn=149&lang=en-US&c=34&n=299 is the B156HAN01 and its the AHVA mode. Not sure if thats better or even what it is.

 

Also moninfo tells me the same thing "AUO9003" with Serial number "8". Nothing else like the model numbers found on AUO website.

 

The AUO panel on my Dell E7440 has a data string which I interpret as meaning the B140HAN panel (14" FHD ticks the right boxes).



Can you see anything similar?

John

 

Nope. Only the plug and play ID of AUO9003. No data string

 

Thank you for checking.

If the AUO panel is AHVA like my E7440 then it's got good viewing angles. Notebookcheck's reviews are a little misleading because they usually indicate that anything that isn't IPS is TN whereas AHVA (also MVA and PLS) are technologies developed by other display manufacturers to provide enhanced viewing angles (more here).

Anyway, if your current panel is AHVA and you have problems with image retention then it's something I'll have to watch out for on my AHVA panel. However, some of the IPS panels have the same problem.

John

 

I believe image retention is particularly common on IPS panels (and similar technologies) while classic ("real") TN panels don't have that problems. The reason most people still prefer the IPS panels are the improved viewing angles etc.

 

That's unfortunate; seems too generic to tell which exact model it is (or AUO forgot to apply the final model nr.). Similar issue in this thread (Russian). Bit of a dilemma; if it's uncertain which type of display you currently have then you can't comfortably purchase a new one; if it's the same series then your image-persistence problem is likely to return.

Yes, have true TN myself; when you push on the screen (as you would when using the touchscreen) you'll see image-deformation and/or local brightening of the screen. This is more pronounced on a TN than on IPS. This might help to make an educated guess as to which type you currently have.

Still, the only way to be 100% certain is removing the lcd so you can look at the stickers on the back:

 

That's a very useful tip.

The two displays I have in front of me behave according to this guideline.

John

 

SO i ordered the B156HAN01.1 and they have sent the B156HTN03.5

Should i return? Or is this alternative ok for my lenovo y50?

 

It will work, but you've ordered an IPS-type and received a TN (for $10 extra?) ... so you have perfect grounds to send it back if you've specifically asked for the B156HAN01.1. And, though both screens are mediocre, the IPS-type is a fair bit better (especially colour space), if these near-identical-models can be trusted:

B156HTN03.6 (TN):



B156HAN01.2 (IPS)



Starting to think the "AUO9003" may refer to different, compatible model lcds; that Series 7 Chronos's is top-quality, nothing at all like these other two. You're still best off to remove your old lcd first and take a look at the stickers; if you have that Series 7 lcd you may be in for a disappointment.
