I'm pretty new to hardware repair, only familiar with basic tasks. Recently, I bought a few GPUs at great prices, took them apart, painted them white, and sold them for a profit. Now I'm seeing a lot of 'dead' GPUs on the market, priced around $10 to $20. These sellers usually mention that the cards give no display. I've noticed many of these cards are in decent condition but just don't display output.
I have a background in disassembling cards, cleaning them, applying thermal paste, and putting everything back together. My question is: should I consider buying one of these non-working GPUs to attempt a repair? Is it feasible to do at home, or do I need special equipment? Can a GPU truly be completely irreparable, or with enough knowledge and effort, could I fix most of them? I'm looking to make this a side gig, but I don't want to waste my time on cards that are beyond help. Any advice?

Generally, repairing GPUs at home can be quite tricky. It often involves replacing chips with components from a donor card, which requires specialized equipment and skills. This isn’t always a profitable venture since the costs can add up. If you're serious about learning, I recommend checking out repair videos from Northwest Repair; they have some solid resources.
I get what you mean about using a donor card. It might work if you stick to similar models for parts. But if repairing isn't an option at home, would it be worth it to buy high-tier cards for a fraction of their price and get them fixed by a professional? It could be a good investment if the repairs go well.
