I fixed my broken monitor with a hair dryer
The core analysis seems to be:> A common issue with these types of components is that the quiescent current which ensures for the internal circuitry to work properly depends on the ambient temperature. If it’s too low and the regular doesn’t have enough supply current left the output appears to be dead.Which honestly makes very little sense to me, and also reads a bit like a terminology tombola. A quick googling did not turn up more material on the idea that voltage regulators depend on the temperature like that, and it would be surprising (generally electronics performs better when cooled).I would expect the problem to be due to a bad solder joint, which would explain why heating it helps since it might make the solder flow a little bit back into making connection (although hair dryer temperatures at 200°F/93°C) are too low to properly reflow solder). Or it might just make components and/or solder expand enough to make contact (which is kind of the same thing but different).All real hardware experts, please explain. :)
