HP 48GX Died Today

[basis]

Hello all,
My trusty HP48 GX calculator of 20+ years died on me today. I’ve been using it every day, including today without any problems (except the last time). I pressed the on button, the screen flashes black, and then off. I replaced the batteries, still nothing. I tried the press the bezel trick but that doesn’t work.

Is there anything I can do that doesn’t require replacing parts that may be a quickish fix?

Thanks!
