No central heating. Hot water ok. Took off Modulation circuit board and found blackened area around one of the pins on PL1.
Like to try a soldered repair but wondered if anyone can recommend best method to clean this area (wire wool?) and do you need to remove the green film that seems to cover the rear of the board in order to expose the metal to solder to?
Not had much experience with PCB's - thanks for help.
