Hmm, now that previous water damage has entered the picture and corrosion was found on the interior, I would proceed with caution. We may be looking at the beginning of cascading failures depending on the condition.
I would bring device replacement onto the table now.
The display or maybe even some other circuitry may be all you need to replace, but water damage is a fickle beast.
