took the cover off, and this is what I found. No idea what happened.
The following 5 videos from the Ali Akbar College of Music Store in California are an excellent tutorial on how to rehead a tabla. The process is the same for the baya. Highly recommended...if you follow the steps he shows you carefully, you should have success (depends on whether the head is good and the shell is round, among other things...)
Tabla workshop information below the videos. Enjoy.

Repair workshops
Broken, out of tune or otherwise unhappy tabla? I can show you how to fix it!
While I can and do repair my own tabla, I don't take on tabla repair jobs, and I won't fix your tabla for you. Sorry. It's just too hard on the hands.
I can, however, teach you how to rehead, pull (tighten) and tune your drum so you can do it yourself.
