I have just replaced the control circuit board in a Bosch electronic-controlled oven (HBN 730 551 B)(Part No. BSH 643 053) but the LED display is “everything showing” – all signs and symbols are illuminated and the display will not respond to any of the buttons. It was like this when I first went to it. I found blown tracks to one of the relays on the control board and assumed that replacing the board would sort out the display, but this has not happened (egg on my face!). Can anyone tell me (1) is there a “learning in” or set-up for the new PCB (I followed the instructions that Bosch included) or (2) do I just need to replace the display unit, as it has blown due to the surge? Help!
Thanks guys.
