Today I was fixing PP3005S power supply. There was same poor soldering points on LED display. So what's went wrong with such simple job? My mistake was with connectors. Unfortunately I connected it wrong. Some 74HC595 registers blow up so I tested everything and except that ATMGA8A is dead. I was too tiered and it was my mistake...
Due to that I'm looking for firmware for that ATMEGA8A. There was some topics about modifications this power supply so maybe flash wasn't protected and someone has firmware?
