I finally had to pick between a full board swap or a deep component fix on a busted TV
A guy brought in a 65 inch Samsung that just went black, sound still worked. My meter showed a short on the main board, but the power supply was also acting weird. I had the choice: order a whole new main board for about $120 and hope that fixed it, or spend maybe two hours trying to find and replace the bad part, a tiny capacitor or chip, for pennies. I went with the deep fix because I had a hunch it was just a blown cap near the HDMI inputs. Took me an hour and a half with the hot air station, but I found it, a bulging 100uF cap. Swapped it for a new one from my bin, cost maybe 10 cents, and the screen came right back on. Felt good to actually fix it, not just swap parts. Anyone else lean towards the harder repair even when the easy swap is right there?

That reminds me of fixing my old car radio last month.
