The IC5 chip is an 8 pin chip 93c66n will try and source one and report back on the findings

Thank you DogP for all your wonderful insight and help, looks like I have a solid lead now to try and get this once working. Once I identify the ic at U5 I shall update and confirm if this resolves the issue! Thank you sooooo much!!!!
