Hi, unfortunately my beloved Beovision 7-40 (MK4) stopped working. Backlight does not get on -> likely power supply PCB4 or panel itself... By chance I could buy another MK4 nearby at good price which is working fine but it does not have the needed PUC-table updates which I need. Instead of getting a B&O technician in to do the PUC-update my idea was to swap the corresponding PCB from the non-working to the working 7-40. Does anyone know on which PCB the memory IC/EEPROM containing PUC-Table is located? Is it on PCB05, 06, 14? Many Thanks!
