Hi Paul and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially and normally yes. However, the service fees/man-hour cost may not make the repairs economically reasonable.
...or are you considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
If yes, please post back with clear pictures of the inside circuitry of the lighted cover.
I realize that the above information may perhaps be not what was expected. Unfortunately, there is no quick-n-easy fix and neither is there a workaround; sorry for having to be the bearer of bad news.
And as my participation is strictly limited to technical & installation issues, please contact Customer Support for any payments & billing concerns; http://ww2.justanswer.com/help or call 1.***-***-****
