MacBook :: LCD Is Dim After Replacing Inverter

Jul 16, 2009

I recently took apart my macbook to see if I could get my wifi antenna nudged to work better. It does seem to be fixed, but when I put the laptop back together the inverter cable shorted to the frame, smelled like burning electronics and stopped working. However, I put a new inverter in and it is not fixed. I was careful to note that the second inverter did not create any smell, but the screen did not even light up for a second. The LCD IS still working, as I can see everything on the screen if I shine a light on it. Except for no backlight, the computer works fine. What could possibly be wrong, and what are my options?

MacBook Pro :: Car / Airline Power Inverter?

Sep 14, 2010

Searched the forum, some useful information. Found the following : On amazon Hypershop's car charger I'd like some flexibility, so the Hypershop one is out of the question (being able to charge my android phone separately from laptop, my backup pc laptop, etc). So my question is, what inverter are you using? I found some on best buy (Cyberpower), but there's no wattage listed in their specs.

MacBook :: Change Out The Inverter - It Showed Light For About A Second Then Went Blank?

Sep 1, 2009

Found a macbook on the cheap. It boots and works via external monitor but the screen has no backlight. I've tried a couple inverters that I know to be good. When I first tried to change out the inverter it showed light for about a second then went blank. Now nothing at all. What should I look into yet?

MacBook Pro :: Sudden Blank Screen - Damaged Inverter Board / Bulb

Dec 3, 2007

To begin with, I own a MBP Intel Core Duo 2.0/2 Gigs of ram. I've had this laptop for roughly 18 months and do not have Applecare. I take extreme good care of all my stuff and still baby it till this day. I have NEVER bumped the laptop against anything, accidently dropped it too hard on the desk or anything similar along the lines. Essentially, looking new. About 2 days ago, I was working with my laptop and I closed the lid which made the computer go to sleep. Everything all normal & no appearance of anything! Around mid-night, I opened the MBP's lid to check my email. (Computer awakes, I can hear the Superdrive awake) then boom, a blank screen. The monitor did not turn on then burn out, it was always off. Similar to if you dim your monitor all the way. I can still see the desktop however, there is no light. If I take my flashlight and point it to the desktop, I can see everything. I called a few places, and they described it is the Inverter board or could be the fluorescent bulb that is damaged. My reasoning for the inverter board is faulty is because when a fluorescent bulb goes out it, it tends to flicker at first. Researching this forum, I noticed most MBP users LCD's that go out, they flicker but, mine just went out and I can still see the desktop. Where can I order the inverter board? I tried [URL] but they're out of stock. I will change the inverter board myself because it will be quicker and I need to use my laptop. It is currently hooked up to an external monitor until I can get this fixed.

Desktops :: Ibook G4 1.42 Dark Screen New Inverter

Jun 14, 2007

I got a cheap 1.42ghz 512mb RAM, 14" screen G4 ibook because it had a broken hinge. I tore apart the laptop and replaced the hinge (screen frame) and put it back together. The screen wouldn't work. I opened it back up and found that the video connector was lose, so I connected it and put it back together. BAM!! Everything worked... everything except the sleep feature when the lid is closed. So I opened it back up, took the magnet from the old frame and put it on the new frame (which was missing its magnet).

When I turned it back on the screen was blank/dark. It showed all the signs of classic inverter board burnout (dark screen, can be seen with flashlight from behind, can be seen on external monitor), so I ordered an inverter board and when it arrived, I swapped it out. Still nothing. The next idea would be the backlight, but that doesn't make sense... I'm trying to figure out what might have happened to make the inverter/backlight go from working fine to not working when all I did was removed the screen back case, screw on the magnet and close it up. I have done a bunch of digging around under the hood and am wondering if anyone knows of a possible ground wire, other connection, easily broken wire, or other issue that might have happened. I'm thinking that it might be one of the power wires that goes into the inverter. It might have broken inside the shield, or maybe I was sold another bad inverter board.

So:

Assumption 1: one or both inverter boards are good.

Are there any connections other than the inverter data/power cable from the mobo and the cable from the inverter to the backlight?

Does anything else (backlight, etc) have to be grounded? Where are these groundings?

Would anything else give the same symptoms except the inverter?

How can I test the backlight? I heard that there are two lights in these machines, so if it was one of the florescent lights, only 1/2 the screen would be dark.

Assumption 2: Neither board is good and that is the problem.

How can I test the inverter board (short of an osilascope) to see if it's working?

Is this a good assumption?

I'm about stumped right now and haven't found any direct help on forums. I'm hoping someone in the Mac community has run into this or has an idea about what could be going on. I'm really hoping that I missed something like replacing a screw that is also a ground or something along those lines.

PowerPC :: IMac G5 LCD Drawing Without The Inverter Hooked?

Apr 27, 2010

I have a tough one regarding an iMac G5 ALS 17" 2Mhz I am fixing. First I want to point out that I am familiar with the innards of these ancient beasts as I have fixed a couple 1st gen iMac G5 as well as iSights and Duos.

When I plug in the cord in the PSU, the 1st diagnostic LED comes on but when trying to start the computer the second diagnostic LED comes briefly on and then goes off. Nothing else happens, no chimes, nothing. According to Apple KB this is the sign of a faulty PSU. Yet, I have tried replacing the PSU and I get the same result.

Now the weird part is that if I unhook the LCD cable the computer starts normally (it chimes) with the display off. What is most puzzling is that it will start with the inverter hooked up but the LCD display cable off but will not start with the inverter entirely taken off but with the LCD cable on. It seems that it is the LCD itself that prevent the computer from starting. I thought the inverter would draw current but not the LCD itself so it's probably something else.

Anybody had anything similar happen to them? Could it be that the inverter is faly but it only draws when the LCD is hooked? Could it be some kind of short in the LCD or something that make it draw even with the inverter unhooked?

PowerPC :: Applecare Cover Replacement Of Back Light Bulb And Inverter Board?

May 1, 2008

Does Applecare cover the replacement of the backlight bulb and inverter board? Looking at a PowerBook that has Applecare - The screen in the listing picture is not too bright. The seller has stated that all is well with the screen, but you never know. I am prepared to go for it if the Applecare covers the screen lighting. Applecare cover on notebooks appears to be worldwide - If the screen lighting conks out overseas, I can get it fixed at the local Apple Store?

MacBook :: Replacing The LCD Screen?

May 6, 2012

My son broke the LCD screen on our older Macbook.  Only the upper screen is visible.  It looks like a LCD screen can be purchased for about $100 and is quite difficult to install.  Can I ask the forum's opinion if it is worth replacing this screen?  He will be entering college in the Fall and will need a PC.  It's the only mac that runs on 10.6 instead of 10.7.

MacBook Pro :: Logic Board Need Replacing?

Oct 12, 2010

Was watching a 720p HD movie on a plane. Movie starts to freeze up. I can move the mouse but the rest of the computer is unresponsive. I force shut down by holding the power button.

Upon restart, all seems well, I login but computer quickly becomes unresponsive again. I force shut down again.

Next restart is over 10 minutes. Gets to login screen but can't login.

I boot from install disk and run HD repair. It finds some problems and repairs them. Reboot. Same symptoms.

I decided it is the HD and archive and install. Install fails. I wipe the HD cleaned and reinstall osx.

All seems fine as I go through set up and login in. A few minutes later same unresponsiveness.

So finally I did what I shouldve done awhile ago which is swap my current hd with my old one. I do and the computer runs fine! I'm at my wits end.

Just so everyone knows, the day before all these symptoms started I swapped my stock 2x1gb ram for 2x4gb ram. I originally thought that was the problem but I've had my original ram in since I've been trying to diagnose and it's made no difference.

MacBook Pro :: Cloning/Replacing Internal Hdd

Dec 27, 2010

i need to clone and replace my internal hard drive. it's 150 GB and almost full, so I'm replacing it with a Seagate 500 GB so I can upgrade from Os x 10.4 to Snow Leopard, and generally have TONS more space

I'm attempting to do the cloning in Disk Utility- I've got the new internal hard drive connected via USB right now, however when i select it as the destination, the 'Restore' option remains greyed out...

I imagine I need to format my hard drive, however I impulsively clicked 'New Image' and it began creating a disk image of the new hard drive...

MacBook Air :: Replacing 128GB SSD Drive With HDD

Jan 23, 2009

I recently bought a MBA with the 128GB SSD. When at the store I launched Word on the SSD version as well as the SATA version and there was a noticeable difference so I decided to pay the extra $700 and go with the 1.86GHz with SSD model. I use this machine for development and my builds carry out file intensive operations that delete and generate a few thousand files (when I generate javadocs). My old Dell desktop from 5 years ago completed this operation in 90 seconds but my MBA takes 400 - 700 seconds. I did some reading and all indicators seem to point to the SSD being fast for reads but slow for writes. Is this correct? I'm not sure I can deal with this slowdown for much longer and I'm thinking a having my SSD replaced with the SATA drive. Will the mac store do this? or is there any less expensive option?

MacBook :: Replacing The Bottom Cover

Jun 22, 2009

My girlfriend's MacBook has some deep scratches on the bottom that a polish kit would not fix. I wanted to buy a new bottom cover and replace it for her. I have found quite a few on eBay, but I am not sure on which model will fit. She has the new white NVIDIA MacBook. I assume that because the motherboard is different, would she need a case specific for the NVIDIA model, or will an older Core 2 Duo case work all the same?

MacBook Pro :: Replacing Screen With Brighter One

Jul 11, 2009

I know it's ancient tech... but I've reverted to a 12" PB after selling my uni MacBook. I've owned two of these 12" PB 1.5ghz previously, both bought new (combo+60gb hd/superdrive +80gb) and the latter one cost me some bad business deal points because I was in a meeting outside in the sunlight and I could not read the screen. I sold it with Applecare to someone on MR last year. The one I bought is used, obviously, and the screen is "fine" no dead pixels or cracks or anything, it just will only be workable inside. Does anyone have any tips on the brightest or best screen replacement I can get for this? This one has a build date of August 2005 so it's been around, though in great condition. A bit "dim" and it might be worth it if I could get a new screen that is somewhat brighter.

MacBook Pro :: When Replacing The SSD Do Just Drop It In And Load Up The OS?

Aug 19, 2009

I am going to purchasing my Macbook Pro through the college student purchase program. I am planning to get the 17" 3.06Ghz 4GB MBP model. I am just getting the weak 5400 RPM hard drive because I plan to buy the Intel X-25M SSD.

I do have a couple questions that I hope can be answered here:

1. Are there any other apple rebates currently going on right now?

2. When replacing the SSD do I just drop it in and load up the OS? Or do I need to format it in a special way? Do I need any other connections?

3. Anti-Glare vs. Glossy, the age old debate. I will mainly be working inside and I will be working with graphic and code development. Which should I get?

MacBook Pro :: Replacing Broken LCD Panel

Nov 24, 2009

I have a Macbook Pro 15.4" (Model: A1211). The LCD screen is broken and Iam trying to replace it. The original panel that came with the laptop was AU Optronics (BP154W01 V.1) with native resolution of 1440x900. Since I could not get the same panel, I ordered the LG Philips, LP154W02 B1 K2, model with a native resolution of 1680x1050.

Now, when I powerup the laptop the screen remains dark and the machine does not boot up. PS: With the damaged LCD connected, I connected the laptop to an external display and everything works perfectly.

MacBook :: Replacing Logic Board RAM And HDD?

Feb 22, 2010

I bought a Macbook 32 month ago and my sister's Macbook is 8 month old. I do some RAM eating tasks, and all she does is type, iChat, and research.

I do Photoshop CS4, Keynote, multitasking, and some games.

Well, the problem is, I have Intel GMA 950, and my sister has nVidia 9400m. She has 2GB of RAM and I have 1GB. And I know what you are going to ask me, and yes, these two Macbooks are the SAME MODEL, just bumped up specs.

Ok, story over, and here is list of what you can do. Please answer as informative or short such as 'yes' or 'no'.

1. Will I be able to swap Logic Board and RAM from two Macbooks?

2. Will it be possible to just swap the HDD AND RAM and me and my sister will be able to keep all the same data, and I will be able to work on heavy multitasking and some good games?

MacBook Pro :: Replacing Optical Drive With SSD?

Apr 20, 2012

I have a time machine backup on external drive. 

I would like to:

1. clean install Lion on the new SSD (120 GB)

2. restore apps from my backup on the SSD

3. keep only data on the existing HDD 

My questions: 

What is the best way to make it? 

Can I just keep the existing system on my non-SSD HDD, and after having Lion on SSD keep just data and delete the system libraries? Or is it better to format the whole disk and restore data from time machine backup (so it is not fragmented..
