LCD Inverter Cables... 4?

I took my iMac 20" 2 GHz aluminum apart the other day to replace a bad optical drive and upgrade the hard drive. When I took the display off, I forgot to mark on the inverter cables which went to which. There are 2 sets on the top and 2 sets on the bottom. Does polarity matter? Should I have marked which went to which before I just unplugged them? I figured they would have had some sort of system where you couldn't plug the wrong one into the wrong socket, guess not...

Hi thebunges
According to > [iFixit|http://www.ifixit.com/Guide/Repair/Installing-iMac-Intel-20-Inch-EMC-21 33-and-2210-Inverter/999/4] it doesn't seem to matter which way they go.

I need a new inverter cable for my MacBook (5.5 years old). Can I get it replaced cheaply, or should I buy a new laptop?

Hi! I have a 5.5-year-old Macbook4.1, and I've been having problems with the display. I googled the problem and found out that I've got a wonky inverter cable. Apparently, the part itself is relatively cheap, but the labor (which involves taking nearly the whole laptop apart) means that the repair is expensive. The quote I got (in Germany, where I live) is 200 euros.
My laptop has been functioning just fine besides the display problem, but since it's already so old, it seems to make sense to buy a new laptop rather than repairing this one. However, someone told me that I should contact Apple first and see if they might cut me a deal on the repair, since I'm an existing customer and they'd want to keep me happy. I tried doing this through the Apple Support site, but I'd have to pay $50 to do that, which seems to defeat the purpose. Going to an Apple store is also prohibitively expensive, since there aren't any very close to me.
So my question is this. Does anyone see any reason why I shouldn't buy a new laptop? The one I would probably end up buying is about $550 (not a Mac), so it's more money than I'd pay for the repair, but...you know. Sunk costs, and all that. I'd be appreciative of any opinions!
Sidenote: in case anyone doubts my diagnosis, here's a description of the problem. When my screen is open, I can see a very faint picture on the display, but the screen is pretty much dark. When I slowly tilt the screen as if to close it, the picture suddenly comes back. So when the laptop is open at any angle more than about 45 degrees, the display is dark.

go on give it a go! what have you got to lose;

IBook 12 Dual USB Inverter Cable with Reed Switch

I apologise if this should go on an older thread. The last time I was trying to access what was called the angle of death thread it took so long to load I gave up.
My question is: my G3 iBook 12" 500 is working perfectly as a backup for surfing and using Word, with a fairly new replacement hard drive in it. But it has started the backlight blanking out when the screen is moved through 90 degrees. From a recent post I noticed yesterday that must have been moved, I now understood that the problem was usually, or often, to do with the need to replace the Inverter Cable with Reed Switch. I live in the UK and cannot get this done locally, but an online UK firm agrees this is usually the problem and he can fit the part and do the repair which with labour costs and postage will be not far off £100.
Is it fairly safe now to assume that this part is the root of this problem?
thanks

Thanks for the reply clarifying the matter. In fact it's now been explained to me that with postage plus vat it goes from £31 plus tax for the part, then £75 plus tax for the labour, then £15 plus tax for the postage, which comes to £142 total.
I think I'll try to keep working at 89 degrees for a bit yet then if I have to I'll buy the part and see if I can get a cheaper way to get it installed. Don't trust myself with such a job.

LCD inverter compatibility

Hello all,
I want to replace the LCD inverter of my laptop HP G61 420SL and I wanted to ask if I can use an inverter board of another
HP G61 laptop.Are all G61 models compatible with each other regarding inverter boards?
thank you

I think that is a serial number so no two will be alike. As long as the inverters are phycically the same, and REO is saying all G61s that have an inverter use the same one, you will be OK.

How to replace the inverter cable? screen gone black in MacBook

Hi
There is no apple service provider in my location. Can I replace the inverter cable without having to take the MacBook to an apple store? is it easy to do? and can I use any inverter cable? or does it have to be especially designed for Macbook?
I have a black Macbook. The screen used to go black sporadically, and now it has totally gone black, and I couldn't get it to work again.
Any advice????
Thank you

Your answer is most helpful and sincerely appreciated, Level 6
Looks like the cable in question being identical throughout "The Black Period".
Looking at it right now it seems easier to patch than waiting for a replacement. Will report back if it wasn't.
Mine is a 2.16 GHz Intel Core 2 Duo 13-inch Mid 2007, heavily hacked.

Inverter Cable problems

Hi, I have a 13 inch Macbook and recently the display has gone black at random intervals, and getting the display back up has become more and more difficult. I cracked it open and no damage was visible. I want to replace the parts I believe are malfunctioning. My understanding is the parts involved are:
-inverter cable
-inverter board
-video cord (possibly)
Now, I want to replace the cable and the board, but I'm not sure if I need to buy a new display screen as well. Any thoughts, suggestions?

I'm experiencing the same problems, my friend.
Have you gotten the chance to try different displays on it, if it's the backlight or not? Exchanged the inverter board? (if you can?) Changed the graphics card? (These can be both cheap and expensive, I have a good suggestion: Ebay and amazon)
Have you also tried a light 'tap' or 'knock' on the display panel (between the machine and the display)?
And just out of curiousity, have you ever bent your MacBook or dropped by accident? These could cause the problems as well.
If it was never dropped or such, this may be just signs of it getting old and needing to be replaced.
I don't want to bump, but I hope this helps!

LCD Inverter

Hello, the other day I dropped my laptop the HP Pavillion 17 notebook and the backlight went out, and due to some testing ive found the LCD inverter is broken. Anyone know if I can get another inverter or I have to replace the screen completly

Hi Anthoknee,
Here is the Maintenance and Service Guide for your model. There is no reference to a backlight (other then keyboard) or inverter for specific parts in the display assembly. You can replace the whole assembly there are instructions on page 65 for removing it.
You could also give us a call for repair options. You can reach HP Total Care at 1-800-474-6836 in North America or start here if you live outside of North America.

Dv7-4180 lcd flex cable

Hi, Anybody know if the LCD flex cable for thew 4180eu is the same as the flex cable for the 4180us? I'm in the US at the moment but my UK laptop needs a replacement cable.
As I can't get the UK version here, I was hoping that it's a standard cable across the versions.
Machine is as shown:-
Product number: XE274EA

PowerBook - Powerbook 17 LCD, Inverter and Video LCD Cable

Hi,
I have the following issue:
My Video LCD Cable is broken (Some of the little cables inside are broken) and i need to replace it. But i'm not sure if the Inverter is also broken. Is there a way to know that so i can buy both of them or only the LCD Cable?
If i only connect the inverter to the LCD, should there be a blank white screen at least?
How do i know I only need to buy those two parts (Inverter and LCD Cable) and it's not also my video card in the logic board that got burned? Can the Video card in the logic board get burned or broken?
When i turn on the computer, i get no video at all, no blank white screen or anything. I know it boots and loads the OS since i get some sounds at boot.
Thanks for any tips i received!
The Powerbook is a 17" 1.67MHZ.

Hi Magpie,
Well that changed with the iMac G5. Here's a quote from this Apple document...
Ethernet port (10/100 Base-T)
The iMac G5 has a built-in 10/100 Mbit/s Ethernet port. The iMac G5 computer can be connected to an Ethernet cable from a cable or DSL modem, hub, switch, or router, or to another Macintosh computer. The connected device can be either a 10Base-T or a 100Base-TX device; the port automatically detects which type of device is connected. You don't have to use an Ethernet crossover cable to connect to other Ethernet devices.
http://docs.info.apple.com/article.html?artnum=86813
I'm guessing that up to the iMac G4s you had to use a crossover cable. I just tried a crossover from my G4 tower to a Window's XP box and it worked just fine.

IMac 17" White Intel inverter cable

I've replaced the LCD screen, but the cable, that comes out of the display and plugs into the inverter connector on the main circuit board, is to short. Is there an extension cable that I can purchase and where?

Is this it? Probably have to call to be sure anyway.

Video iPod LCD Ribbon Cable

I am currently trying to replace my screen in a g5 video ipod. The only problem im having is getting the ribbon cable in its slot. Does that have a clip that opens up or does it slide in with pressure. I dont want to force anything so I thought I would ask around. Thanks in advance with any info you can provide! Take it easy.

T400 LCD Inverter Questions

Hello Everyone
I'Ve got a few questions about the LCD Inverters. First of all:
Is there a difference between 41W1479 and 41W1478? There must be, because they are different numbers, but wherein lies the difference?
Secondly, I've built in a 41W1478 card where there was a 41W1479 before. Had lots of flickering in the first try, then re-installed the card, and after that, it stopped working completely. Any idea on what i did wrong?
Looking forward to your answers

The inverter that was inside before didnt work (screen was all dark), the new one was flickering. Then i turned it off, re-connected the inverter, and when i turned it on again, the screen was all dark as well...
Are you sure its the motherboard? because replacing an expensive part isn't really the solution i was hoping to find, tbh

Macbook a1181 display blanks out replaced the lcd inverter still blanking out

Replaced inverter still blanking out.

OK--so this is an original MBP. You are in the late 2008-early 2009 section of the forum, so I am going to request that your post be relocated to the original MBP section.
Have you tried an external display? If you get good graphics on an external, it will be further conformation that the graphics chip is OK.
I am puzzled as to why the original display worked, but two separate replacements did not. I have heard of the brightness indicator getting stuck all the way to the left, so that the display remains black. Can you see the desktop at all by shining a bright light through the apple? If so, maybe you could go to System preferences>Desktop and see if the slider is stuck, and if so, move it to the right.
Good luck!

L2440X LCD DVI cable problem - Windows 7

I have been running the L2440X using a VGA connection (with KVA switch) as I transitioned from an XP system to a new Windows 7 system (which has a NVIDIA Quadro FX 380 display adapter). I have finally shut down XP and transitioned to using the digital DVI connection on the display and the display adapter). The cable shipped with the display was a bit too short so I ordered a longer DVI-D dual. However when I rebooted with the longer cable, Windows 7 could not recognize the display and went to recovery mode which failed. When I rebooted with the original cable (DVI-D single) it worked fine. I have been assured from several sources that the DVI-D dual cable should work in this configuration and it must be a display problem. Is there any way to get the DVI-D dual cable to work with the L2440X display?
A secondary question - the image properties shown on the On-Screen Display lists 3 options - D-Sub (analog), DVI (digital) and DP. What is DP???

DP is display port.
From what i know you would need to use the correct cable for the DVI-D format, so for your monitor you would have to get the DVI-D single cable.
