iM 4,1-14,4 Completely broken mid-2010 Imac. Can it be saved?

[ultrawideband]

Hello everyone

A little context:
A friend of mine, owns a mid-2010 (A1311) imac.
He was lucky enough to have both the HDD and GPU fail almost at the same time
First he was presented with graphical errors
After a a few trys, it was booting

I ordered a new GPU card from ebay but it was taking too long to arrive

So he kept using the imac in that condition

At some point the HDD broke as well

He tried to disassemble it but he made things far worse
He managed to bend some pins in the CPU socket plus I also believe that a couple of pins on the edge of display ribbon cable were broken


So far we have an imac that has:

1. bend pins in the cpu socket
2. (probably broken pins on the edge of display ribbon cable)
3. broken GPU
4. broken HDD

The imac was handled to me in case I was able to save it.
The truth is that it had been collecting dust of quite a few years
But now, I am willing to make a descent try to fix it
I know that it's on old machine but I would really like to save it from the landfill

So far I have tried (and believe succeeded) in straitening the bend pins on the CPU socket, using a sewing needle

Question: It there a way to tell if the straigtening of the pins was successful without the rest of main components (gpu, hdd, display)?

When I connect the motherboard to the case (+CPU, RAM) and plug in the power cable, the 1st led stays lit while the 2nd one blinks really slow (~once every 5 sec)

The power button doesn't seem to to anythink (maybe I didn't align it correctly)

How should I proceed?
Should I buy on of those diagnostic cards?
And if so, where should I plug it? To the mini pcie port of the wifi card?

Assemble the iMac back, without GPU, HDD and LCD panel.
Try powering it up. If it chimes and the fans spin, then perhaps you have fixed the CPU socket.
But then, the cost to buy the GPU and fixing the LVDS socket will be higher than purchasing another working iMac 2010.
If you still want to re-use any parts that can be saved from the land-fill, I would like to suggest you converting the iMac to a stand-alone display with small expense.
