Northridgefix? Tronicsfix? TheCod3r? (Louis Rossmann, of old?)
There's several of them, but it really depends on the value of the device more than the cost. A lot of what Northridgefix repairs is valuable for the data being recovered more than anything, where the value proposition isn't clear. That said, if someone's paid $2000 for a GPU, I can understand their willingness to pay $300 to get someone to painstakingly microsolder some components back on.
At $70 per hour it doesn't take long for repair to become more expensive than a new item.
