Laptop repair shop recommendations

Looking for recommendations for a shop that repairs laptops, but actually does board repair. Like actually diagnose a shorted main board and repair it whether it's replacing a bad cap or shorted mosfet. Not geek squad that will confirm a shorted board and say you need a replacement board. I have a pricy gaming laptop that died. I was able to confirm a shorted board, but dont have the access to replacement parts. Suggestions appreciated.
