With the ic in the correct way round this time. Now you're talking. Ok So I am at the first instance of $SVS so what am I looking to do now?

Right then, opened up with Hex Editor Neo on Windows 7, the file is just full of FF Using control F and trying $SVS or even just $ gives nothing. The programme said the transfer was successful so I can only guess that went successfully. Does that mean the chip is blank/faulty and dead? Thanks again

OK, what programme am I using and on a mac or a pc? Thanks again.

I started this in a previous post a couple of weeks ago at the link below: https://www.rossmanngroup.com/boards/forum/board-repair-troubleshooting/15699-is-this-more-of-a-software-thing-macbook-pro-sn-c02hng7jdv13 I have read the chip with a chip reader and now have the .bin file so what am I...

Hi, So I have .bin file read from the bios chip. What needs to be done now?

How is ASD run I have ever used it before. Download it from somewhere then run it from memory stick?

No problem, I will be looking at it when it comes in but how can ASD be run? From the computer switching on and running it from USB? As far as I know, all functions are OK when it is on. Thanks

Nice coincidence, I will be watching when I get the computer in.

820 3437 - It switches on and switches off randomly from what I am told. It has not been brought to me yet, but the person says that "someone ran something on it" and it needs a new SMC. I have not done anything with SMC's yet, but from what I know if there is a problem with the SMC in any way...

With careful placement I have managed to get the cable in despite the bent pin and now all is well. Switching on again and all fine. Movie uploading to YouTube as I type.

Oh goody, found the short only appeared when the screen was connected, looking at the connector the last pin is damaged so is that just a new cable? Does the cable go into the screen therefore the screen needs taking to pieces if that is possible?

Didn't notice there were so few, still looking for the component, but will do that tomorrow. Been at work for the last 14 hours, I have a cold and my head hurts so am going home.

Update on the no graphics issue, looking at the schematic pin 28 29 and 30 end up at U8300. Cannot find u8300 yet, but may have found U8330. Putting U8330 aside, pin 28 39 and 30 are shorted to ground, so is L8300 and, I am guessing everything that goes back to at least U8300. Looking for other...

Tried that a few hours ago with my iPhone flash. Didn't show a single ray of light through the apple symbol so I'm guessing it is the later version. It is a retina, I'm on another steep learning curve.

If I find the very same component I will use it. I don't know if it is backlight or graphics issue, but I an looking for voltages at the moment.

Hi, I got the board view file and they are different boards, but it did lead me to the faulty component. R7120 was burnt out. I replaced it from a MacBook Air board. With the board in the computer, and power connected, it gives a green then red light, logic board gets warm as though it is...

I have looked for the same component on a MacBook Air board 820 3437 and found it, looking for the same type of thing and not found it yet so still looking.

What an Engels idiot I am. I just answered the question and never thought about the answer. Ok so R7121 and R7122 and 10 Ohm each and looking at the schematic they are in series so adding them together, between pin 27 and 28 should give 20 Ohms. 0.909 is pretty much open circuit so something has...

OK probably not gonna be able to as I have just found it after finding in on a 2013 MacBook Air board then found the same component on the MacBook Pro board

I am thinking I need to look at Q7180, where abouts is it on the board?
