I was perusing my Dell.com account for my laptop and looking at the build specs (Studio 1537), and noticed something that confused me a bit:
1J656HLiquid Crystal Display 15.4WXGA, Light Emitting Diode True Life, 0-2BD, Lg Philips Lcd
and
1M135CBezel, Cold Cathode FluorescentLamp, Camera, HEPURN .....
new screen/inverter/ backlight installed. NEW screen still black, but visible with flashlight. Went ahead and got ANOTHER inverter off eBay and tried that - screen still black. Haven't ever replaced a backlight, and the operation looks delicate (and expensive to HAVE done) ...
View 10 Replies View RelatedI'm looking to buy a M1530 LED WXGA+ screen (1440x900). I currently have the stock 1280x800 CCFL. I have some question that I'm hoping some of you would be able to answer:
Will the LED screen fit normally within the stock CCFL backing/bezel?
I'm looking at screen descriptions, for the LED's I don't see "inverters" listed as included but in some, though not all CCFL have it mentioned in the description, is this something that's no longer required? or is it built into the panel?
What is a good price for these panels? The panel I'm looking at is a Glossy 1440x900 LED screen for $205CAD with shipping and taxes included. Good price? bad? Is it possible to get it cheaper?
Concerning batterylife, I have a 9cell and am averaging of 3.5-4hrs of usage with wifi on and screen in one level just before full brightness on Power save mode. Will I see a very noticable increase in battery life? I keep hearing people spout "30%" are there any actual tests?
I have been pondering whether my Studio 1537 came with a LED backlit screen since Dell didn't include a Centrino 2 sticker although all of my laptop hardware meets the req. for Centrino 2. Who knew what else Dell could pull?
I decided to fire up my Studio 1537, Inspiron E1505, and Mini 9 to do a comparison with the LCD backlight on full power with Notepad maximized (lots of white).
The E1505's LCD was about a year old and is CCFL. The Mini 9 and Studio 15 are brand new and both were advertised to have LED backlighting.
The E1505 looked dim and yellow compared to the Studio 15's CRISP white color, while the Mini 9 had an almost purple tint to the white screen. I work with white light a lot and can say the E1505's LG CCFL was around 4000-4300K for color temperature while the Studio 15 was more around 5800K and the Mini 9 at 6200K or slightly higher.
The problem with white LED's is that they have a shorter lifespan (~20,000 hours) compared to red, blue, and green (usually 100,000 hours). This translates to noticeable decrease in white light output after 2.3 years of non-stop 24/7 usage.
Another major difference I observed is that the CCFL at max brightness is equivalent to the LEDs at about 40-50% brightness!
dell is sending me the led instead of the ccfl i have now so i want to know the differences....

View 7 Replies View RelatedI recently had my screen replaced by dell dispatch for my studio XPS 1340. My hinges were loose, instead of replacing just the hinges dell dispatch had replaced the whole screen. My question is can you tell a difference between CCFL and LED. My specs is LED I just want to make sure the technician, replace with the right screen. Is LED thinner than CCFL if so what is the technical spec of thickness between the two. Is there a way to check if you have a 1.3 or 2.0 webcam.
View 10 Replies View RelatedThere was a discussion on this subject before but I can't find it. Currently I own XPS 1330 with nVidia GPU and LED screen. My GPU died a while ago, was replaced.
After that I applied copper mod. But it will die some time in future again. So I'm thinking to replace my mobo with one that has integrated GPU.
A month ago I received my new laptop from Dell. After a short inspection I discovered that instead of 2 HDDs only one was appearing in device manager.
After a bios check that confirmed that only one HDD was installed I called Dell Support. The person allowed me to open the laptop and to my surprise there were 2 HDDs but one of them was not fixed with screws and it was able to move freely inside.
Those from Dell decided to replace my laptop and one week later I received a new one .....
I like repairing laptops as a hobby. I recently bought a M1330 laptop without a screen and with a small video card problem. The laptop still worked on external screen, but showed some lines.
This was due to the NVidia gpu problem. I managed to fix it by using a hot air soldering station(Youtube video). To decrease the chance that it arrises again, I also did the copper mod(description). This meant that I could finally use the laptop for my work if I could just install a LCD screen.
Since I have spend quite some time on repairing the laptop already, I decided to invest some additional money to upgrade from a CCFL to a LED backlit LCD. I ordered a new cover, screen and LED LCD cable.
When I assembled all the parts, everything fits perfectly .....
So dell didn't upgrade my screen when they replaced my lid today and still interested in buy a LED WXGA for my lappy
So I found a couple screens for the 1340 on Ebay but ... not sure on a couple of things:
I have a Arctic White Lid with a 2MP webcam and ccfl screen, is the current led screen or the one in the m1330 is compatible with my lid ?
So dell replaced my m1330 with a SXPS 1340, but they did not have any LED ones available, so they sent a CCFL.
They agreed to swap it with the WLED screen. My question is, is the casing different for the CCFL and WLED like it is on the m1330? I know the LED casing is thinner on the m1330.
I have an M1330 with LED and love the display. I came across such a good deal for a refurb Studio XPS 13 that i could not pass it up - (P8800, 4GB, 500GB 7200rpm, 512MB N10M-GS,
Wireless 1510, Bluetooth 370 for $875 shipped). Only problem is that it has a CCFL screen instead of LED.
Will the difference be really noticeable? Am i going to regret it?
I have an XPS M1330 purchased about 2 years ago.
The screen went extremely dim permanently one day when the battery reached its near absolute low. For some reason the screen came back to a brightly lit life after a system restore. The same problem occurred again and sadly after sitting on it a few weeks I did not have a restore point old enough to troubleshoot with the same solution.
Now I'm not sure if system restore really had anything to do with the monitor crapping out because I've never heard of such a scenario, but I'm just going to throw it out there on the off chance that it does .....
The CCFL WUXGA screen belongs to a precision M90 and is almost 3 years old. Keep that in mind for this review.
The RGBLED is way brighter than the CCFL; at nightime, I would only use the minimum brightness setting.........................
are there any comparison shots between the two different types of displays. i am getting a m1330 soon and would like to save as much money as i can.
View 15 Replies View RelatedI'm having a problem with the back light of my laptop. I have a Studio 15 that I bought around 1.5 years ago.
I don't know why the back light randomly stops working. When it happens I turn off the screen and turn it on again and it works fine. Any clues on what is happening?
What are the symptoms when your LCD backlight craps out? The screen on my i9300 is black but I can see images, although it is very very dark, like the lcd is working but it's not lighting up. Also when the lcd crapped out, there was a burning smell.
If I do need a new LCD, would it be worth it to replace? My laptop runs great and I'd love to keep using it.
Windows device manager recognizes the graphics card. latest drivers are installed. running Windows 7.
LCD backlight turns on, however, the screen constantly stays an offwhite colour.
when i connect the laptop to a VGA monitor or to a TV through S-video, it connects and everything is displayed perfectly on the external screen. the laptop LCD is still lit up a offwhite colour.
How do I disable (and keep disabled) the backlight on my XPS 13? I can use fn+f6 to turn it off, but it ends up turning itself back on when re-logging in or coming back from hibernating, etc. Running Windows 8.
View 4 Replies View RelatedI got my E6400 last week and I found that everything all right except the color of LED screen, it's awful.
The color of the screen is pale, i had tried to calibrated the graphic settings but it doesn't improve too much.
Also, i saw some posts here said that the LG screen is better than the Samsung screen, but I can't agree with that because my screen is LG.
Is it normal for LED backlight screen that the color is more pale than the CCFL backlight screen or just the screen of mine had some problems?
I have an issue with my XPS M1730. Intermittanly the screen will go black during use.
It is clearly the backlight going out as on very close inspection i can make out contrast of light and dark areas. Plugging in a secondary screen on duel duplicate mod works fine, but laptop remains black.
The laptop screen will suddenly come back on at random, even if left in the corner with no-one using it.
The backlight failure also happens at bootup alot. I found also that leaving the laptop overnight (when backlight failed to come on) that it will not usually come back on, but within minutes of pluggin in the secondary display it will suddenly light up and work ok. It will continue to work till put to sleep/ closed down...........................
I happen to have two M4400's on me, both have the RGB-LED. Figured I'd take some pictures to compare the bleed on both backlight's.
The one on the left was delivered this week and the one on the right was delivered two months ago.
Curious, other CCFL or RGB-LED M4400 owners, do you find your bleed patterns similar?
I have a Dell XPS M1330 and have tried to find a solution for a screen that just doesn't want to stay at it's brightest setting.
I have adjusted all Battery profiles (including the "on battery" setting) and the screen seems to adjust to lowest background light settings every time I close the lid to my laptop.
I have adjusted all known settings for this, and still no resolution to the problem! Every time I close the lid to my laptop, windows makes a dis-connect sound (notification), you know, the sound it makes when you dis-connect a thumb drive or other USB connection.
I have a Dell 17" laptop and the screen shows this blueish green vertical on startup.
After a few minutes of warming up the line goes away and the screen looks normal. The line reappears on reboot though.
Looks like this is a problem with the backlight/inverter. The laptop is almost 4 years old, but I would like to keep it going a little while longer
my work pc is a Dell inspiron 1520. it is mounted on Ram stand in my tow truck. the problem i am having is sometimes now when im driving down a bumpy road the backlight goes out.
to get it back on i either have to close the lid and open it, or shut it down and reboot.
i was thinking its the switch that tells the mother board that the lid is closed when its not. Is there any way to disable that switch so the backlight is on permantly
I will be calling Dell tomorrow to get my keyboard replaced due to the Numlock light not working.
My current keyboard has not got a backlight would it be possible to get a replacement keyboard with a blacklight?
I recently had my laptop apart to put different thermal paste on the cpu, but now my backlighting isnt working for the keyboard. does that little ribbon cable control that? Its kinda hard to get it to stay attached. If not then is this a normal thing for these keyboard lights to go bad?
View 10 Replies View RelatedMy mom's XPS 1330 just had its backlight give up the ghost and it's of course post warranty, so I'm wondering a couple of things:
1. How much that repair is going to cost and
2. Is there a place that is great for this?
I want to purchase a backlight keyboard for my dell studio 15. I cant find anywhere to purchase it and if it helps i got the stock keyboard.
