RE: SR-52 rebuild project (SR-52 942058 LTA4176)
Replacement of the Display Driver
Another step forward ... After replacing the TMC0534 and the TMC599 with no effects we have found out that one of the SN27882 had a corroded pin which broke ... Replaced that the display turns on but ... None of the numerical keys work, it goes in LRN mode and some of the keys like the first column is ok, sto and rcl seems ok with few others ... Now the question is how can we understand if it’s a keyboard problem or a TMC534 or a TMC501 issue ?? Thanks for help !!!! Edoardo & Alberto |
