Hi all
Despite my complete lack of experience, i have managed to fix part of an LED matrix board we use for work. The LED matrix is split into 4 boards and originally, 2 of those boards were faulty. I could clearly see the problem with one of those boards so used the other as a donor to see if i could fix the problem. This worked great and is fully operational again. Im now looking to bring the final board back to life. I've narrowed the problem down to one of three chips and am looking for replacements for all 3 (pictures attached).
Could anyone help me source replacement parts for these please as i have no idea what they are or do, im only capable enough to re-solder them having watched tons of videos by Louis Rossmann
Many thanks
