IMac display connector on logic board

Does anyone know the part number or part description for the connector on the logic board that connects to the display (tdms) cable on an iMac G4? On the logic board, where the old one was, is the notation "j10". The person I got this iMac from tried upgrading the hard drive and accidentally ripped the connector off because they didn't unclip the tdms cable from the drive first.
I figure soldering a new connector on should be a pretty easy fix, but I'm not sure what part to order. I know a few places that I could probably order it from, once I know what I'm ordering.

Seems to me a similar question has appeared in these boards, and
there are a few people who are regulars, that may know the answer.
Been awhile since I've seen the posts regarding this topic, so I can't
just put a link to the correct discussion at this time. Maybe the post
could appear as part of a search; such a dragnet approach may be
daunting and the yield well beyond the scope of your needs.
A slightly different discussion than I recall, but near the neighborhood:
http://discussions.apple.com/thread.jspa?messageID=9096347
Is there a close-up picture here of the connector in question?

Good luck & happy computing!

closet on the floor, but have not gotten time to look into it.}

Run the monitor on an iMac with a dead logic board?

Can a Mac mini be used to run the monitor on an iMac with a dead logic board?

Apparently my iMac was just dirty. When the tech tried to start it today it started even though when the tech tried to start it yesterday nothing happened. So no need to fix anything.

Late 2006 24" imac - broken sata connector on logic board

How to fix broken sata port on logic board? It snapped off, apparently it wasn't soldered on very securely. Now I can only boot my machine with external usb drive. Help!

Hi Aaron
Bummer, I only see 4 options.
1. Continue to run from an External HD, FireWire 400 is faster than USB.
2. Find someone with the tools and skill to re-solder a connector back onto the logic board.
+(problem is, not to many folks can or will, because it's nearly impossibly)+
3. Buy a new Logic Board for $600+ > http://www.welovemacs.com/apim242inco26.html
+(problem is, that the iMac isn't worth $600)+
4. Buy a New or Refurbished iMac.

Personally I'd put my money on #4, instead of spending another dime on a 4 year old machine that also needs a Graphic's Chip and who knows what else.

Can an external display work if logic board is broken?

Recently I had my early 2007 24" iMac's graphics card fixed. Three weeks later the main screen went all black but my external screen works and I'm able to use the computer just fine when I mirror the display.
I gave the imac to the same repair place that changed my graphics card and they saying the logic board is broken.
I was thinking the problem was display cable or something but logic board is a much more expensive thing to repair so wanted to double check here if its even possible for the computer to work with an external display if logic board is broken?

The correct version of the AHT works just fine on all Mac's. But you need the correct version of it.
For the Late 2011 models that is only available as a Online, Internet Boot system where the computer is booted from over the Internet.
Restart the system and at the chime hold down the Option+d keys until you see a spinning globe in the center of the screen. Then once it full boots and you select a language run the test.
Also it is best to have the computer Wired to your internet router with a cable.

Help, my 3+ year old iMac has a fried logic board

I have an iMac G5 PPC 1.8GHz 20". Within the past year or so Apple replaced the power supply as my serial# fell under the G5 Repair Extension Program. It was working fine until recently when the screen would lock up and require reboots. Now it will not even boot up. I took it back to the Apple Store and was told it had a bad logic board. The tech showed me the bulging capacitors. The estimate for the repair is a whopping 600+ bucks.
I am very reluctant to invest that much dough when I was already thinking of selling this one and buying a new Intel based iMac. Besides, I need the money for gasoline for the next week! I thought I could attempt the repair myself until I found I could not get the part any cheaper than what Apple was going to charge.
This really bugs me as I've had the computer for just over 3 years. Any ideas on what I should do? Try to sell the remaining good parts? Can it even be used as a monitor? The display is still in fine shape. Hard drive is good too (250G). Thanks in advance.

My nearly 3 year old iMac died a couple months ago and after jumping through some hoops to get the date of purchase reset to what it should've been, I took my iMac in to a local service provider to get it fixed under the repair extension program.
I was then told when they diagnosed my computer that the logic board and power supply were both dead and needed replacing. When I brought up the repair extension program I was told that it only covered the power supply and not the logic board.
Should I contact Apple Customer Relations or should I go back to the people who diagnosed my computer and plead my case with them?
P.S The serial number of my computer falls into the range posted on the Repair Extension Program for the Video and Power Issues page, so I'd imagine my computer qualifies since it isn't 3 years old yet.
Thanks

Can you tell if it is a display problem or logic board problem

I have a 17 inch aluminum mac book pro. I bought it from a reseller on ebay in February. Recently I have been having some display issues. It has taken it longer and longer for screen to come back on from sleeping and the other day it did not come back on at all. I thought it could be a faulty graphics card because it is one of the models that has the faulty card in it but when I took it to my local mac authorized dealer they said that because there was damage to the hinges of screen, they thought it was a display issue and suggested I get a new screen for upwards of 900 dollars. While testing it they plugged it into an external display and the screen turned on for a few seconds. When they closed it, it did not come back on. Back at home I did a similar test and plugged in an external monitor and it worked for a while but as soon as i turned i closed the lid the display went off again and now I cant get it to display even when connected to external monitor. WHen i turn it on i can hear the chime and i can control the volume and keyboard brightness. My question is whether this is a simple display issue, a faulty graphics card issue, or a logic board issue? Please help me. I am going to fix the computer either way I would jsut like to know if it is a screen issue that I could replace myself.

If the Macbook Pro was made between 2007 and 2008 it maybe the Nvidia issue.
I suggest you take it to an Apple center and have them run the test.
The damaged hinge should not affect the test, I would think.
Be warned though, just because you have exactly the same symptoms does not mean it will fail the test or more importantly, if the test does not generate a fault code, Apple will not repair.
Did this start after the 10.5.7 update and more importantly did you run the SMC 1.3 update as well?
If you can get the machine to start properly, deleting the /var/vm/sleepimage seems to eliminate the symptoms of not waking. Before you delete is take note of it's size.
It's my opinion that this file also caused the machine to hang after the SMC 1.3 update when the lid was closed the first or second time. The machine then continued to run generating lots of heat. You may not have noticed and just found the machine with a flat battery one day.
If that is the case, damage is done and the symptoms are the same as the Nvidia extend warranty issue except not covered!

Imac G5 needs new logic board

Hi,
My imac G5 was revving up quite a bit and acted like I was downloading something all the time. I thought it might just need the fans to be cleaned but I took it into the genius bar and was told that they guy "thinks" that I need a new logic board but isn't positive and would I like to look at the new imacs. ( I love looking at the new imacs but it's not in my budget). He said it would cost close to $800.00 to repair my imac. I edit video on it and it's also become the family computer. Any suggestions? Do I put the money into replacing the logic board? Do I put money into expanding the memory on my macbook pro that only has 2 gb of memory?

Has it been shutting down unexpectedly?
There was a repair extension program for some of these iMacs which suffered from defective capacitors on the Logic Board and the Power Supply. It's been closed since Dec. 08, but I've heard of people appealing to Apple Customer Service anyway and getting the repairs covered. First you should open the computer and determine if the capacitors on the Logic Board are swelling or leaking at all. If so, you might be able to convince Apple to do the repairs. 1-800-275-2273. If at first you get turned down, ask to speak to a higher level rep.
Tell them how unfair you think it is that those who had the problem before the program closed were covered, and it was just your bad luck that your computer lasted a bit longer. You can also say that had you opened it up earlier, you probably would have seen the bad capacitor issue developing before the program closed. They are numerous little cylinders about 3/4 inch tall. The tops should be perfectly flat. No brownish gunk. Inspect it very carefully.You won't be able to look inside the Power Supply easily, though. If your iMac is not an iSight, it's very easy to open up. Just three screws at the bottom. Have a look here for illustrated instructions for your model. If it is an iSight, probably best not to try; a bit too complicated. Or you might just call the repair service and ask exactly why they thought it needed a new Logic Board. Did they see bad capacitors?

Need Info to repair broken power switch connector on logic board

Hi folks,
I had some bad luck this week. The power switch connector broke off my daughter's Ibook logic board during a HD upgrade attempt. Unfortunately, it pulled enough of the etch that I can't determine where the connections use to go.
I would like to salvage the board. So, if anyone has access to a schematic for the G3 Ibook, 14" 900Mz logic board, I would appreciate some info about the circuit. Specifically, to what components does the switch connect. I already identified one side is grounded and the other side is pulled up to 3V through a 1K resistor, but that etch also went somewhere else. I suppose the gate of a FET transistor. Any help would be greatly appreciated.
Perhaps someone with a dead logic board could trace the circuit with an ohm meter.
Regards,
Spencer

Hi spencer,
Apple doesn't make circuit diagrams available, sorry. I've done or had done component level repairs of iBook logic boards before, usually to re-attach connectors which have come off, but unlike yours, these ones have all come off leaving the trace on the board.
The fact the traces have come off isn't good, as you can probably tell. It's also a 4 layer board, so where the vias go is important. I have a couple of dead logic boards from 500,600 and 700mhz iBooks. The 14 inch logic boards are essentially the same as the 12 inch ones. These pictures are of the area of a 700mhz logic board.

My iMac got a new logic board, now my HP printer doesn't work

I have had my Intel iMac 24" using OS 10.7.5 in the shop a lot lately. One of the things they replaced was the logic board. Now my iMac seems to be working great, but my HP printer stopped working. It's and older printer, Officejet All-in-One. I tried removing the driver and software to reinstall but it says the disc will not work because the iMac is no longer a PowerPC. That's how old the printer is. Is this a techology thing, is the printer just to old, or is there something I can do to fix this. Should it at least recognize that a printer is connected. The printer is not recognized at all, that is, it says no printer is connected and even when I try to add a new printer, it does not show up in the list. So there is no way of trying to add it back, to the iMac, there is no printer connected as far as it's concerned.

How can you transfer files from an iMac with a bad logic board?

This is in reference to my "Nothing but a blue screen at startup!" post. He took his iMac to an Apple authorized repair shop and he was told that the logic board was shot. He has decided to get a new iMac but he's wondering about all the photos and other files he has on the old hard drive. What are the ways that he can get files from the old hard drive on to his new one when he gets it? Thanks in advance for your help with this!
Eric

Hi Eric!
roam's method is a very good one!
I don't know if this will work because of the bad Logic Board, but another way, may be to use Firewire Target Disk Mode.
The ailing iMac would have to be Firewire enabled, and you would need access to another Firewire Mac.
Good Luck!

Display problems, bad logic board?

Hi I'm a first timer here! I have a iBook G4 14" 1.33ghz laptop I am fixing for someone. When it boots up, the screen looks like you are watching TV with old rabbit ears. You can make out the mac logo and what not, then the screen goes blue, like the basic blue background, and it looks perfect, then once the desktop comes up, it all fuzzy again. I've replaced the LCD screen, AND the lcd cable that connects to the logic board. Same results. I guess the last part would be the logic board to replace? Does anyone have any suggestions?
Here are some links to the pictures to show you what is going on...

inverter board controls brightness, the lines in your pics look more like the logic
since you have a stick of RAM, try another module or maybe remove it if you have on-board RAM
would be good to connect to the external display if the adapter is available - it would confirm bad logic board if the same lines are on the external display, it wont completely rule out the board though if there are no lines

IMac 24inch 2.4GHz Logic Board Core 2 Duo

I have a white 24 inch Imac 2.16 ghz computer got in 2007.Having problems with mouse cursor not showing on monitor
takes 10 to 15 seconds to come back.I think it is the video card aNvidia GeForce 7300GT.Found info on google on this problem
in some sites they are saying tha apple knew of this problem buy by looks of things they let it go without telling owners .
I do not know it this true or not.
If some one has a anwser about this or knows how to contact Apple to see if they can fix this problem.

Hi Ian, it easily could be that, but let's try this...
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
PS. Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or 3rd party add-on, Check System Preferences>Accounts>Login Items window to see if it or something relevant is listed.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

IPhone 3GS display connector?

Hi guys i have big problem with iPhone 3GS display,so i need your help here,i was changing battery on my device and the when i wanted to put back display i saw that connector 1 is hard to put on on connector on motherboard so i saw that conncetor one don't havetwo pins ,i know that i need new cable or new display can you please tell me can just replacew another ribbon cable because my LCD display is not broken,if you didm't understad this is the problem,so can i do anything or i need to buy new LCD display.

Your question is a little difficult for me to understand. If you think the LCD Display connector on the Ribbon Cable #1 is damaged, the fix is to purchase a new LCD Display. The Ribbon itself is not truly a replaceable part that I know of.
When working on an iPhone 3GS the iPhone must be OFF, or you risk damaging the LCD Display or the Logic Board components that control the LCD Display.
I do not understand how you know “don’t have two pins”? I have never heard of this problem? If you really know that two pins are out, then also examine the #1 connector on the Logic Board to be certain is has not sustained damage too.

Repair of logic board

Hello. Attempted to add 2nd hard drive to mid-2011 Mac Mini 2.3(i5). Unfortunately, IR connector to logic board broke. Company that sold me 2nd hard drive & video instruction(via online) stated that they could not repair. Is this something that Apple can fix or it it lost and I have to purchase a new Mac Mini? Thank you in advance.

Talk to Apple Genius Bar. They will tell you repair cost.
No one here is a certified repair tech who is actually loking at your unit, so we can only guess at the cost.
Good luck.

Time Machine doesn't recognize old sparsebundle after new logic board

Installed new logic board in pre-Isight 20" iMac due to capacitor swelling and kernel panic. I had also erased the internal HD. I was able to restore all my files to internal HD from Time Machine backup on the 1TB Time Capsule. Now I'm trying to back up my restored iMac to Time Capsule, but there is insufficient space. Time Capsule has three sparsebundle files: one for the 20"iMac prior to new logic board, one for a Powerbook, and one for a newer 24"iMac. Time Machine wants to create a new sparsebundle for the restored iMac, but there is not enough room and I would like it use the residing sparsebundle so that I will have backups prior to the point the new logic board was installed. I tried just changing the name of the old IMac Time Capsule sparsebundle file to the new sparsebundle filename that Time Machine creates when attempting backup, but that did not work. Any suggestions?

1. I thought of just deleting the old sparsebundle in order to make room, but it was a less elegant solution because: a) I'd have to do a complete (i.e. lengthy) backup when really only a few things have changed (mostly software updates) since the restore. b)if something should go wrong with that process, then I've lost my backup file to restore the computer. True, I could archive the old sparsebundle to another drive, and then delete it from the time capsule, but somehow I think there should be a quicker, less labor intensive way that doesn't involve bringing in another hard drive.
2. I believe you can restore any Mac with any time machine backup. If you boot from the system disk, go to utilities, and select restore from time machine backup, it then allows you to pick any of the files on the disk that time machine has backed up to. After all, even though Time Machine thinks this is a new computer, the restore that I just did makes it essentially the same computer that I had before the failure of the logic board--the desktop looks exactly the same. BTW, the Apple authorized service center that did the logic board replacement had put a clean version of 10.6 on the internal hard drive, and I was unable to use that system to do the restore--it just hung up. I had to do the restore using my system disk CD (and basically downgrading to system 10.5.8)
