Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
I think you will need to replace the console, period. It sounds like that degree of damage.
I could find a source for that console for you... if you will double-check and identify your Schwinn exercise machine for me. I couldn't find a '5350 P' at first effort at a search.
