Motherboard repair - potential bent pins on the LGA

Is there anyone in the CPT area that specialises in motherboard repair?

Brother in law shipped me his old mobo and CPU (a Gigabyte GA-Z270-Gaming K3 board with an i5-7500) seems that some pins on the LGA may have been damaged / bent in transit (was all working before he sent to me). When putting the system together and booting up receive 5 long post beeps and then it resets and repeats. All indications for that post error would point to CPU / mobo and upon close inspection of the LGA it looks like there is some damage to the pins.

TIA.

Have you tried sorting them with a pin and a magnifying glass?

Unfortunately I have not got the steadiest hands and didn't want to do more harm than good. I also only have one functioning PC which is currently my source of income as I'm working from home so cant keep ripping it apart to test the new mobo etc. Was hoping someone in the CPT area had the tools and a test bench to work with etc.

To be completely honest, the test bench is likely to consist of plugging in after fiddling with the pins that look out of place to see if it's fixed.

Looks like at least two bent pins. You can try get someone to bend them back, but in most cases pins are fragile and trying to bend them back results in them breaking off entirely which then isn't really replaceable. But at this stage you don't have anything to lose to try since the board is already bust if it can't boot.

Why did he have to remove the CPU before shipping it?

Do you trust him? How do you know it wasn't FUBAR before and that's why he sent it

Check for a datasheet and figure out what signal goes to those pins. You may find you can run conductive paint on the underside of the cpu to a neighbouring 'pin' in order to connect the missing signal on the cpu to what it needs.

Nobody really does this. You need to gently fandangle those pins with a toothpick & micro tweezers, they're quite fragile.

Thanks all appreciate the feedback figured that my own manual intervention was my only option, was just hoping for a hail mary, someone who had experience / luck with fixing this sort of thing before.

Sadly the reality is the hourly rate just makes it not worth doing. I'd rather sell you replacement gear even if I make less than the 3 hours it could take to troubleshoot it. At least I can offer you a warranty on that.
