Is the lcd still good? If so ... 1. Keep it you might need it for testing in the future. 2. Start learning how to refurbish cell phone screens and use this one as your first project. 3. Sell it to a local shop or on ebay.
No they have way to many parts with most with different motherboard connections. A1226,A1260 LED display versions both compatible 2.2, 2.4, 2.5 and 2.6 processors all will swap between each other. The A1211 A1150 compatible to each other - they use the LCD display.
Lemerise is right. That is your isight camera cable and unfortunately there is no fix for that, I repair on component level with a stereo microscope and it is nearly impossible to fix! Your only option is to pull the glass and replace the cable or buy a used display and selling the old for parts if you wanted. That's it! See within the wire there are 10 strands that are microscopic if 1 of them is not together with the rest it will not work so your working on 2 wires the outer and the inner with 10 and there is four wires total.
Trying to tell you exactly what chip needing replacing is toooo vast! It could be the chip, resistors ,caps or inductors or even shorted traces that require jumps. You need to search the net for boardview and schematic for your board and check for short to ground with multimeter youtube can help if you look right. No light on the magsafe usually means the one wire over voltage is not working , feel around on the board and see also if there is area that is super super hot obviously this means the circuit is shorted. That's all I can do this is a very simple answer to a very in depth answer. Good luck!
