Y50-70 4k lcd panel replacement - yellow issue

Hi guys,
It has been 4 months since I bought my y50 with 4k display and still no solution for the yellow issue. I tried to call support and also to send it back and change it with the full HD model without any success as I bought it from john lewis store.
I'm really disappointed about all the support system..I'm going to fix it by myself.
Does anybody know where can I get a 4k compatible LCD panel replacement online??
Thanks loads

hi marcolino86,
Thanks for being civil and sorry to hear about your trouble.
Besides the SAMSUNG, 15.6 inch, LTN156FL02-L01 screen that's being used on the Y50-70 (see page 93 of the Y50-70 HMM), the only compatible UHD (3840×2160) panel that I've found is the SHARP, 15.6 inch, LQ156D1JX01 which uses the same Embedded DisplayPort (eDP) 4 lanes signal type but I haven't seen one went with this upgrade.
- List of 15.6" 3840x2160 displays
Seing that you have the Y50-70 FHD model, you will also need to change the eDP cable to support UHD if you're planning to go for the upgrade.

Alternatively, you may also want to consider doing what others users did on their Y50 FHD model where they changed the stock TN display to an IPS display (see this thread)

No. I just got two of my X201 on my side and none of them have a gap in the bezels. And one of these two was a guinea pig for a panel swap so I ended removing and re-installing the bezel too many times. Still sits perfectly flat and with no flex or gap at all:

That's more normal.

Can you take a photo of the damage? Once before I saw an LCD that arrived truly internally cracked. The ink was in a perfect circle, writing off any user fault.
In the worst case situation, it might be worthwhile to call Lenovo and purchase a new screen. If you purchase one through them, you can get warranty support for the new screen. I realize that is a terrible alternative, as you should not have to invest more money, but it is the cheapest route to get a functioning LCD.

Z61m: LCD panel replacement (WSXGA+ to WUXGA)

I own ThinkPad Z61m (Type 9450-HAG). Unfortunately the LCD panel does not work any more (only top third of display works).
I consider replacing of the LCD panel (WSXGA+, FRU no.: 13N7020).
Is it possible to replace the original panel with WUXGA panel - 13N7198 or 13N7178?
If it is possible, is it enough just to exchange the panels or it is also needed to replace other parts of notebook and/or upgrade BIOS or other software?
Solved!
Go to Solution.

It should work no problems. In fact, you could probably use your old inverter. CCFL backlit LCD screens use a two pin connector from the inverter to the LCD. This connector is the same accross most if not all manufacturers.
I tried replacing a 15.4" WXGA LED backlit LCD with a WXGA+ CCFL backlit LCD. Now you might ask yourself, can I convert to LED backlit LCD. While it may be possible, I don't want to say yes just yet. Anyways, what I had to do is disassemble the LCD and remove the screen. I disassembled the original WXGA LCD and replaced it with the WXGA+ LCD. Too bad it didn't work. It wasn't because I had damaged it. The LCD originally didn't work. It had an awful display. I just wanted to know if it was possible.
The conclusion is that these parts are quite interchangeable. CCFL backlit LCDs generally use the same connectors for both the backlight and display. I am not sure about LED backlit LCDs, but it would be understandable that the manufacturers maintain some kind of uniformity. After all, they produce these LCDs for all the laptop manufacturers.

IBM Thinkpad T30 lcd panel..replacement in due?

My lcd display panel is blurry (i.e. brightness level is not as expected though pressing Ctrl+Home)...
Maybe should entire unit be replaced? In this case, how to locate the correct version as (2) types, XGA and SXGA are
available..
Where can i find panel FRU number?
If you fool me once, shame on you...
If you fool me twice, shame on me!

Welcome to the forum!
A couple of things come to mind here:
a) Go into BIOS>Configuration>Display and make sure it's set on "high". Press F10 to save and exit.
b) Is the LCD slightly reddish/pinkish on initial boot? If yes, your backlight is dying and need to be replaced. Most people prefer to replace the whole LCD panel, though.
c) If your LCD is not red or pink on boot, your inverter may be on its way out. Replacing it is a cheap and easy job, and that's where I would begin.
All the FRU numbers and instructions on "how to" can be found in the HMM that can be downloaded here:

IBook has no backlight even after LCD Panel and Inverter Board Replacement,

I just got hold of an iBook G3 800mhz that works excellently aside from the fact that it has no backlight. Usually, I can figure this stuff out pretty well, and I had some parts around, so I replaced the inverter board and LCD panel. Still no backlight. I reset the PMU and NVRAM, and of course turned up the brightness in System Preferences. I can't figure this out. What else could it be?

Hi Guy,
As Rhonda suggests it's probably the inverter cable. I've repaired two recently both were broken at the hinge point where the cable is wrapped in this silver flex tape. One was the red wire, the other I forget. I diagnosed this by pushing the wires together at the hinge. Once I found the broken one and isolated the point that it was broken I soldered it together and used shrink tube to repair it.

Replacing the LCD panel in my 23" Apply Cinema monitor (A1082)

Hi,
I have a 23" cinema screen (A1082) which has a cracked LCD panel. I've order a replacement LCD panel but how do I take my existing monitor apart in order to change the LCD panel out? There doesn't appear to be any screws to dismantle the screen...... thanks

1) Using a thin tool like a screwdiver, pry off the side plastic strips from the top down. Older units are harder as the glue is applied more generously. It helps if you warm it first, lets say with a blowdryer.
2) It is easier if you remove the stand hinge pins using a 6mm allen wrench. You can probably get away skipping this step if you don't mind more work later.
3) With a small phillips head, remove the side retainer brackets.
4) At the bottom where the clamshell joins, pull a small tab which slides a hooked retainer releasing the clamshell. Older units may have one on each end, newer units have one at only one end.
5) Pop apart the clamshell and slide the guts out.
Good luck finding replacement parts for these. Mine has a logic board that died in a power failure and I am stuck with finding a broken display and buying it for the working parts. Unfortunately Apple does not sell the parts to end users.

Replacement LCD panel - good source

Who would be a good dealer for the LCD panel only? I don't want one in a housing, cost way too much.
I will be working on a white 2ghz core 2 duo. can be matte or glossy.
I'm doing this for a project & want to learn more about doing this type of work, so please don't advise sending it in.
Thanks!

I've used powerbookmedic once before, busted a key off my old powerbook one time. It showed up scratched & I was grumpy about it, wrote them a not very nice email. They did try to contact me & make it right tho, so in their defense. The broken key was in really good shape & used the suspension, which was the reason it was broke, so really, it all worked out.
I will keep them in mind, looks like with a coupon code & cheaper shipping rates, better price than ifixit right now. Thanks!
Anyone else have input please share!

What's the latest Jan. 2010 spec LCD panel model #? (e.g. 9CBD, 9CA0, etc.)

Just wondering if anyone who has a 2010 assembled 13" MBP or recently warrantied MBP can confirm the latest Apple display spec model # (e.g. My MBP was built in Sept.09 and has a 9CBD panel) that is being used?
Got the dreaded light leak developing on the side and hinge edges of my MBP -- but considering that my colours/calibration are pretty much bang on for my eyes as well as the fact that I've painstakingly applied an Anti-Glare film 100% free of lint bubbles LOL -- my conundrum if the latest spec'd panels are really any better or if it's still a lottery on whether you get a good panel if replaced under warranty. The last thing I want is to go backwards in quality!
Also if you've gone through the warranty process I'm curious on whether you have any say on whether it is another 9CBD that goes in or if you can specify to them that you're only satisfied if a Jan. 2010 9CA0 (or whatever # it is) is put in?
I am planning to wait to see if Apple quietly updates the LCD panels in the MBP line at the Jan. 27 iTablet/iPhone OS4.0 event before taking it in anyways, but hopefully someone can shed some light into how Apple have been going about dealing with the light leak issues. Thanks again.

Thanks for your kind cmments matrixxzero. I agree rockykoston I will replace my keyboard eventually myself too, with all the stories here I'm terrified to hand my laptop into service, apart from not having the spare time, Idon't want it to come back scatched, damaged and/or unfixed. That doesn't augur well for Lenovo guarantees. I am fully cpable of servicing it myself but many customers aren't and shouldn't have to.
As I say the other issue is model lines. Our Chinese friends have proven they can maintain quality and innovate now but their shere manufacturing muscle means it's all too easy to have too many models and too many variants with too much crossover.
Why drop a great design like the Z710, only let down by a middling to poor Nvidia chip and introduce new 17.3" models with absolutely no maintenance covers and sealed batteries!! They should have upped the Nvidia chip (the same as the Y50) and a better WLAN card. Same with the 15.6" models - evolve the Z510 to have a case like the Z50 but the same or better components again. Similarly the Y50 should have been an evolution of the Y510 not a step down.
Lenovo has definitely gone cheap in the upper end of the consumer range, when they needn't as there are tons of cheap laptops from the brand.
Most of the reviews I came across for the Z510 described it as having very good build quality and since I changed laptops three times from the same store within my purchase period I had chance to compare closely, with at least Toshiba and Acer. I would not agree with these reviews it's OK but not great. The metal upper case fooled me a bit but it's less sturdy than a cheap i3 HP laptop it replaced. Again for around a $1000 it should be better.

Weird scratches in lcd panel (23" acd)

Well, i'm back. This 23" is the third one I got from Apple, the two previouso one's exhibited ghosting & the pink issue.
This one doesn't have these, only some backlight leaking when viewing black images fullscreen.
The thing is, the build quality on this one is below par, I think.
1 - If I tap the lcd panel itself on the right top corner, it moves about a mm. It's a little loose, and I can 'push' it inwards about 1 mm.
2 - There is 1 stuck pixel (red) in the bottom left corner, that doesn't bother me that much actually.
3 - There seem to be 2 scratches in my lcd panel. I can't describe it very good, but a picture will do the trick. Here are 2 of them. They're not stuck pixels, the shape doesn't match up right.
http://users.skynet.be/bk318948/screen4.jpg (the largest scratch)
http://users.skynet.be/bk318948/screen2.jpg (small one in the bottom)
Should I take this back again? The build quality doesn't resemble my 2500 euro I paid for it back, in july 2004.
This is my third replacement though, and I don't want to go through that process again, so either they give me a complete refund, or they compensate me in any way for this lower build quality.
Am I overreacting with this issue or not?

Are T4X0s lcd panels a complete fail?

At first we had the "vertical band" in our displays:
http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/t410s-vertical-band-in-my-LCD/td-p/245040 (12 pages)
And now, people are coming up with bright spots on their displays. Some of the users already replaced their displays before due to the "vertical band"!
http://forums.lenovo.com/t5/T4-T5-und-neuere-T-Serie/T410s-Wei%C3%9Fe-Flecken-auf-dem-Display/td-p/4... (german)
I know those T4X0s series ThinkPads are thin as hell. But they break much too often. Lenovo has to find a solution for this. A friend owns his T410s for 5 months now and it's the second time he has to carry in his ThinkPad due to display issues.
Just wondering, when the first thread with desperate T420s owners will emerge... Is this really such a hopeless situation?

My T400 has had a bright spot since about the first week, so issues might not just be with T4x0s. I haven't had a chance to ship it back yet to have it fixed (ship it as it is under 3yr warranty) as the machine is in constant use.
While my T420 was being worked on recently (on-site service) I asked the tech about display issues. He also services Sony and other models. According to the tech, he sees display problems more often in other brands of laptops. He said that it generally happens to students or other highly mobile people, and they notice it after the machine is removed from a backpack or other bag. He finds these odd as the lcd panel will be spiderwebbed or have other issues but the glass/ plastic in front of the panel will have no damage. He blames the trend of thin & floppy displays for these issues.

LCD Problem -- Replace display or use MBP as desktop?

Internal video is usually dead on my MBP 3,1 -- dark grey screen (but not black) with various vertical stripes. External display works fine. Internal display periodically comes back to life for no apparent reason but then fades back to its usual unhelpful state over time or if it is touched, however lightly. Per Apple, I do not have a defective nVidia card. Initally, Apple proposed their $310 fix which I've had twice before (paid by Amex)-- once for a SuperDrive another time for a logic board. Then noticing two slight dings in the case, the Apple genius said that the machine wasn't eligible for the $310 deal, as such machines had to be pristine. This notwithstanding the fact that Apple had previous logged the dings as cosmetic. At that point, the new display went up to $700 and I was told that I'd need a new logic board if I wanted a meaningful warranty. Obviously, I'm not spending $1200 on a three year old laptop. So I decided to do it myself, something the Apple genius conceded made sense.
I've replaced the data cable with no success. My next step is to replace the inverter cable, although I doubt this will do anything because the brightness controls on my dead LCD seem to work fine. That leaves me with inverter (unlikely) and the actual LCD to replace.
Do I go ahead with the LCD which runs from $150-250. If it succeeds, I may get several more months out of my Mac. If I don't, I'm looking at a new logic board which I won't buy, leaving me out $300.
I'd be tempted to suck it up and pay too much for a new Mac but I really need a 15" model with an Expresscard adapter slot -- something that no longer exists. If I buy a new laptop which would be hardship right now, it would likely be a Lenovo W510 (i7 processor, 500gb hard drive, good display for photo editing, etc.) all for $1785. My preference though is to keep this laptop going and put those funds toward a Mac desktop which I also need.
Any suggestions on the display replacement? Shall I go out and do it? What is the likelihood that I'll do it but won't succeed. Could the fault lie with the motherboard, as well?
Thanks for your suggestions.

ps - Time is of the essence. I need to resolve this over the next week.

Thanks for the clear-headed analysis. Ordinarily, I would agree with you especially since I never actually sell old electronics. I just give them to friends and family who are behind me on the technology curve. Here's some additional information.
I've been using the MBP primarily for Photoshop but am finding with CS5 that it is slow. It's my only real computer. I have a Lenovo S10e that runs OSX but that's for fun. I have four external hard drives that use eSATA connectors (I shot 600gb of photos last year alone.) I'm starting to work with video and the MBP stutters on playback. So I've accepted that a MacPro or something like that with a high-end monitor is in my near future. I have to travel next week for an assignment with a working laptop.
I've priced the current line of MBP's and am looking at $3000 which I'd rather put toward my desktop. I can come up with the money but that will set back the desktop project and leave me with a laptop that isn't cut out for the bulk of my work. The 17" which accepts ExpressCards doesn't come in an i7 configuration and isn't very portable. If I go with a 15" model, I still need to keep my old machine around to transfer files on an as-needed basis to a Firewire hard drive.
I've seen many posts in these forums about the nVidia issue with users describing symptoms similar to my own. The solutions have included replacing the data cable, inverter cable, inverter, display and (less often and usually at Apple's expense) the motherboard. Assuming that I can live with the consequences that something else will inevitably break, the question I'd like to find an answer to is whether based upon:
the display occasionally functioning perfectly;
(ii) the external display working perfectly; and
(iii) the graphics card passing Apple's diagnostic test
I can assume that the motherboard is ok - for the moment. (I realize that every time I reopen the case to change wires, disassemble the display, etc. I'm increasing the likelihood that one day the motherboard won't be ok.)
Any thoughts?
Thanks again for your help.

Purchased a LG FHD LCD panel and broken.

Hello everyone, I am using T520 4242- RU2 model in Thailand. I tried to upgrade my LCD panel from 1366*768 to 1920*1080. I bought a panel in e-bay and I replaced by myself. After few months, it becomes yellowish color on white image. So I removed it and replace default one. Well, I would like to buy a new FHD panel again. Do you know which one is recommend? AUO or LG or Chimei or whatelse...?? if you have recommended P/N or FRU, could you let me know? thanks and best regards,

Hi, I have a 3 year old Macbook Pro 13" and I accidentally cracked the outer screen of my mac book, however the LCD panel is fine and works well. Please advise what to do

Hi, I have a 3 year old Macbook Pro 13" and I accidentally cracked the outer screen of my mac book, however the LCD panel is fine and works well. Please advise what to do. I live in India and I have gone to authorised Apple technicians and they infomed me that I will have to replace the LCD panel as well even though it is not cracked, is this really true or can I just change the outer shell? Also they say that they cannot do it in India... can I do it myself at home?

Since it is 3 years old find a local repair shop that can replace the glass Only. you may have to send it out to a Non Local shop for that but there are some that specialize in doiing that on Mac notebooks.
Apple will ony replace the complete screen enclosure with all normal parts included, LCD, Camera, Aluminum housing and glass as one unit. Which is very expensive. Or you could just use it as a desktop system with external monitor and buy a new notebook.

DSC-HX90V LCD panel shows images upside down

I bought the DSC-HX90V for my wife in late June, and we promptly took it on a three-week cruise and visit to Italy. The camera performed well, even in low light, and the telephoto worked phenomenally: Thanks to the 5-axis OIS, we were able to take 30X zoom images with exceptional clarity and no blurring (even when shooting distant ferries, containerships, etc. from the deck of a cruise ship). The viewfinder was a great convenience, and it was easier to use than we might have guessed (popping it up and flicking the back element of the finder out quickly became an instinctive process). But--and this is really weird--the camera developed a fluke after several days of use: the LCD began displaying images upside down, in both shooting and review modes. At first this happened sporadically, then it happened all the time, and finally--in the past few days--it reverted to displaying images correctly. Fortunately, there were two workarounds when the LCD was acting goofy: We could use use the viewfinder (which was immune from "upside down syndrome") or pull the bottom of the LCD panel out an eighth of an inch or so, which resulted in upside down giving way to right side up. I haven't yet called Sony's warranty service about this, but I'm guessing the problem is in the LCD's "selfie" position sensor. It would be great if it could be solved with a firmware update or system reset, but that's probably too much to hope for. In summary: Great camera, but with an annoying flaw that will need to be fixed.

Hello Imboden,
Sorry to know that you are experiencing this issue with your camera. Please try to reset the settings in the camera by pressing MENU then Setup then Setting Reset. You can also do a Power Reset by turning the camera off, removing the battery. Press and Hold the On/Off button for a minute and then release it and reinsert battery. Turn on the camera and test the LCD screen.
If the LCD panel still does not work properly, I would recommend sending the camera in to http://repair-camera.com/SonyRepairHome.aspx for evaluation and repairs.
If my post answers your question, please mark it as "Accept as Solution".

Zander
