Samsung NP700Z5C Screen Upgrade Attempt

okay i got the screen today (yay, one day early)
i took the screen out, bezel is done (throw away)

but here is the bad part, i ordered LP156WF4(SL)(B1) matte screen it is slim enough to fit back in the housing.
but the bracket is different (i could use double adhesive tape to solve this)
but but but when i boot it up, led lights up, but but but screen goes blank......
so i put the original screen back in and the screen works fine.

did i get a bad screen? or is it firmware related????

any thoughts?

 

I may have solve my own problem regarding this screen.
I believe that LG and Samsung use different LED inverter to power up the screen.
So the new LG screen might be receiving too little or too power from the 40 pin cable.
This is my only conclusion I could think off.

I tried to take the Samsung LED inverter off, but three coil like things are attach to the screen? (this could be the light bulb?)

Is there a website that shows how does LED screen look? diagram?? disassemble?

 

Samsung Ltn156kt06-801

active area 344.16 x 193.59 mm (WxH)
bezel area 349.03 x 198.24 mm (WxH)
outline dimension 359.3 x 222.45 mm (WxH)
outline depth 4.0 mm <-- this is important
lamp shape 4 strings

LG Lp156wf4-slb1

active area 344.16 x 193.59 mm (WxH)
bezel area 347.55 x 196.9 mm (WxH) <-- note difference
outline dimension 359.5 x 218.53 mm (WxH) <-- note difference
outline depth 3.4 mm
lamp shape 6 strings <-- note difference

this is the major difference i could find on both screens.
do you think that lamp shape has to do something?
Samsung being 4 strings and LG being 6 strings

That's it for tonight, let me know your thoughts.

 

i found the reason why the LG screen doesn't work with np700z5c.

The min volt require for the LG screen is 7.0
while Samsung's min volt is 6.0
Because of that the LG screen doesn't fully power up.

any work around for this?

I did find a LG screen that has the same spec with min volt of 6.0.

Hopefully this will work, going to order this on the weekend and I should receive it by sometime next week.

 

ohhh...this is disappointing. Thank you for sharing....

I don't know which model they ship for the samsung NP780Z5E-S02US here... but maybe that one is compatible...

What is the other model you are going to order?

Perhaps samsung screens are the way to go instead of LG. Have you seen the LTN156HT02-B01 ?
Looks like that one is used in the NP780Z5E-S02US ...

Good Luck!

 

i also thought about the np780z5e screen (LTN156HT02-B01), but i can't located the exact spec on this. I could try this too, but how the quality??? according the np780z5e forum here, people say that screen is washed too?
(i want to see the screen quality, before i gamble on samsung lol)

the part i'm going to order is N156HGE-LG1 is made by innolux. but the actual panel is made by LG and it meets all the requirement as the current samsung screen. (6.0 volt min)

N156HGE-LG1 has 60 % gamut color and viewing angle of 70/70/60/60.
LTN156KT06-801 has 45 % gamut color and viewing angle of 45/45/15/35.
(samsung suck really bad)
LP156WF4-SLB1 has 60% gamut color and viewing angle of 80/80/80/80.
(its the one i ordered)

hopefully better luck on the next screen

 

fingers crossed

 

Also since the bezel essentially gets trashed whenever it's removed, when you finally settle on a screen you can find a new bezel on eBay from China for ~$50 USD.
np700z5 bezel | eBay

I need to order one eventually, I just don't want to spend the money.

 

thanks for the tip... i can see 1 for $40 but still expensive for some plastic....

can't wait for the results of Elf4U ...

 

I just got an email from the vendor saying no matte screen for N156HGE-LG1.
They only have gloss screen.

What should I do....

 

You could try the

N156HGE-LB1

or

N156HGE-LA1

 

No matte screen for both model too. >.<

is matte screen something we can live without???

Does the signal category make difference?
whats the difference between LVDS & eDP??

-------------------------------------
N156HGE-LG1 is shipped, it will be at my door on Wednesday. Hopefully everything goes well with this one.

 

matte screen and glosy have nothing to do with the signal or the connector to pass the signal.
So you can choose for the glossy and it will work.

Difference between glossy and matte is just a mater of personal choice...

LVDS and eDP differ in the hardware (signaling and connector). With cable and hardware hacks it is possible to get an eDP screen working but trust me... you don't want to go that route...

The N156HGE-L11 seems to be available in matte but i don't know if is is the same quality as the LB1, LA1 and LG1 .....

 

N156HGE-L11 has outline depth of 5.2mm, in order to work in the np700z5c the outline depth has to be under 4.0mm. because of that it's very limited. T.T

the part i ordered is suppose to be a matte screen, so when it comes i could say it for sure.

thanks for the info on LVDS & eDP.

 

You ordered N156HGE-LG1 matte? Where?

 

i ordered it from laptopscreen.
hopefully they are sending the matte screen.

--------------------------------------------------
update

i just received the screen from fedex.
but they send it me different one.
I ordered the N156HGE-LG1, but they send me N156HGE-LB1.

 

i connected the screen to the laptop and it does power up.
but, its flashing red, blue, white....... i don't get it
any thoughts???
if i reinstall the samsung screen, it works fine.

----------------------------------------------------

after searching around, i saw that this might be cause by a bad gpu, so i dig further and saw that this manufacturer has an factory burn in test and it seems that this screen is stuck in the factory mode. i saw the solution for regular desktop monitors (by accessing menu), but how do i do this for a laptop screen.

i have sent an email to support and waiting for their response.

----------------------------------------------------------

response from the vendor is reinstall gpu driver. take the battery out and reinstall. -.-
one thing i found is that N156HGE-LB1 is used by Sony Vaio SV-T1511M1E/S and according to notebookcheck this screen is touch screen.

i been thinking, does all 40 pin screen has the same layout? meaning is it possible for each different company to set different pin to their own??
ex. samsung pin 15 is power on while lg pin 15 is ground?

 

That's the first thing I thought. Usually when a screen flashes an array of colors it's a factory burn in test. I'm not sure how you could turn it off, but maybe it's programmed to run for a certain amount of time? You could try leaving it running for a while and see if anything changes.

 

RGB flash still going~!!! <--- at least no dead pixie that i can see

https://picasaweb.google.com/lh/photo/SCekHrEkz_Mqaj4RF2cMK9MTjNZETYmyPJy0liipFm0?feat=directlink

i think i might open the bottom case up and reset the cmos and the battery..
do you think it might help??

i'm open to suggestion

 

after further testing the screen (still running the burn in mode).
i have say that i believe our screen has single channel lvds. (as it is share with the webcam)
i found a used series 7 gamer lvds cable from ebay (thank you Brinings), hopefully that will help, since series 7 gamer use 1080p screen..
i will keep updating as soon as i have more updates.......

 

I responded in the other thread, not too sure that cable will work for you.

 

i know what you mean, its worth a try. since that will be the last option i could do.
the reason i wanted to have a 1080p lvds cable was i read it some thread in the HP DV???? notebook section and they were saying that lvds cable was different with lower resolution and 1080p resolution. (different part number in the same model, since 1080p was an option)

i took the laptop apart completely and tested with reset cmos, no hard drive and still the new screen is flashing RGB.
the samsung screen work.

so before i send the screen back to the vendor for defect??? i would like to try the 1080p lvds cable in the other samsung notebook.
i'm just hoping that the connector is the same in the motherboard. (cross my fingers)

 

i suspicion was right.
current cable in np700z5c doesn't use all 40 pins.
https://picasaweb.google.com/lh/photo/mgUIIFQHmgqNGlR-OQ08aNMTjNZETYmyPJy0liipFm0?feat=directlink
looks like about 5 pins are missing.
i will update more later..

 

What was your original rsolution? 1366 or 1600?
The first uses 1ch lvds the second uses 2 ch which can be reused for 1080p which normaly is 2 ch....

 

original resolution is 1600x900

 

and? any news?

 

Any news od that?

 

original screen has unique pin layout, whats why none of the screens worked, check data on pdf before buying any screen to compare which one is easier to modify lvds cable for.

Slim LCD screen for Asus Zenbook UX51VZ WUXGA IPS LED laptop display 15.6" I cant find model nr to check full details of that screen, but I was told by ebay seller:
sorry answer you late because of the weekend here.
Yes, this screen can compatibel for ltn156kt06-801 upgrade, you can be sure buy it

and it was a lye its eDP port on LP156WF4-SPB1

 

Perhaps the newer screens from the NP780s or the 800s for example would be a better bet? They're cheap on the 'bay and as the rest of the laptop looks about the same, will possibly fit. Unless Samsung have completely redesigned their connectors and internals... I also have wondered about the possibility of a 1920x1080!

 

If you have an NP700Z5C (2012 model) I would NOT assume that a panel from the NP770/870 (2013 Series 7 / Ativ Book 8) is compatible. Of course I cannot rule it out, but they are quite different in so many ways.

 

Yes, I'd agree with your scepticism, but as the OP seemed to be getting a lot of screens and then sending back ones that didn't work, it seemed like a possibility!

 

Oh, I see. Got it.

 

Are there any news about this issue?
i am VERY interested!!!

I want to upgrade my screen, too.
Does the 770z5e model work?

 

As previously posted, NP700Z5C and NP770Z5E are quite different in many ways. It was a redesign, not just a small refresh. Hence I would be surprised if the screens are compatible. I haven't seen any post confirming or denying it, though.

 

Reading this thread got me rather worried...
I personally have a HP EliteBook 8560w which has a Samsung LTN156KT02-301 HD+ screen.
According to panelook this screen has a 1 channel 6 bit 40p lvds connector.
Does this mean that just like you guys I'm stuck with this @!!## screen forever, or can I still upgrade to AUO / LG? I cant open the pdf on panelook cause I'm broke on p coins...
So I don't know if the pinout is different.
I really need advice on this matter.
