Alright, so I did both the option test and the "t" test. For the "t" I got a black screen for awhile and the beeps continued. Then I got a screen with a weird looking icon flashing around the screen with a battery icon on the bot…
UPDATE: After letting it sit for 5-7 minutes, I get a white/gray screen with a flashing question mark and mac logo...is it just the hard drive or could it be the ram?
Any testing I could do...??
I am not tech savvy enough to do that haha. The new logic boards are already on the way. Thanks for your help though. I am going to try to sell those boards on ebay. We shall see how they do.
So sad that the rest of the Logic board can work perfectly except the circuitry near the backlight connector. How much can I sell The logic board for AS IS or FOR PARTS?
John,
Sorry for confusing you.
I currently have 2 Macbook's on me, both black and both 2.4 GHZ Penryn Models. I also have an extra 820-2279A logic board, 2.4 GHZ that doesn't work once it hits the OS, but it does boot (perfect for testing display …
Update: was able to connect it to the external monitor and everything works fine, browsing, wireless, speakers...everything. I can now see a feint image on the LCD of the MacBook.
What should be my gameplan? Keep in mind I have another MacBook pen…
Alright, just got the laptop from Fedex.
Turned it on, got the chime but no picture. I then turned it off and reset the PRAM, got both chimes after 20ish seconds then let go of the keys and still no picture. I also tried to reset the PMU/SMC and s…
Alright, so, I opened it up and took the motherboard out. I have to say, the motherboard looked really good other than dust and I saw a tiny bit of corrosion right under the power pads on the motherboard (820-2279A). I cleaned the whole motherboard …
Will do man. I have plenty of friends that are tech guru's. I will send them on over. Hey, I just posted a new thread/problem, thought I wouldn't mix threads.
I will keep you posted on this one though come Friday
Alright, I think I have a gameplay for when the machine arrives. I will be in contact with you on Friday and tell you what is going on. Thanks for your speedy responses.
By the way, I was able to fix the other guys computer with your advice. You th…
How do you reset the PRAM? Sorry, I am still learning all this stuff and I wouldn't be back to your site if your advice didn't work the first time. I am a huge fan of your knowledge.
It is a black MacBook, I thought that is the penryn model. I will know more on Friday when I get the actual machine from FedEx. I am going to start with connecting it to an external monitor to make sure the logic board still works. If it does, then …
Re-applied the thermal paste and tried to boot it up. Same thing happened. I also tried to boot with a snow leopard disk in and got the same thing.
Looks like I will be buying a new board...unless you have any other ideas...
Also, how can I get th…
Wow, I had no idea about that. I will go ahead and scrape the old thermal paste off and apply some new paste. I also didn't secure the logic board to the case because I didn't think it was necessary for testing, but I did secure the heatsink to the …
So, I just finished installing the motherboard back in and connected all the different cables to the motherboard. I did not connect the battery or the battery connecter to the motherboard.
I plugged in a magsafe power supply to the motherboard. I …
Excellent. I will go ahead and put it back together tonight and either respond tonight or tomorrow morning.
Thanks again for your help. I will let you know how it goes. Cross your fingers!
The pins snapped off the end of the cable that connects to the motherboard. So, I will have to replace that and have already bought a cable on ebay. Should be here in a couple days.
Can I put the computer back together and power it on via the power…
I just checked on the parts. They seem dry as a bone, but last night when I was cleaning it I did dip a toothbrush into alcohol and scrub, not sure if that is considered "soaking the board in alcohol".
Also, I think you misunderstood, the…
Thanks for the speedy response. The parts are currently drying on a paper towel.
Before I took it apart, when I did plug the AC adapter into the magnet port I would get a very solid green light and then about 8 seconds later get a dim green light. …
