Hello, welcome to Just Answer, thanks for requesting me! It is most likely a bad control module. the one connected to the display...95% chance of that. There is a 5% chance that there is a bad (burnt or broken) wire connection to the printed circuit board. Tell me a lot about your technical skills background and what test instruments you have on hand so I can coach most effectively from here. .
