Non-functional HP 33E
I have an HP 33E that isn't working properly. Here's a video:

As it shows, the display lights briefly with zeros after turning on, then flickers, displays some random characters, and dies.

Any suggestions what could be causing this? Is it a bad chip, or something I might be able to repair if I take the circuit apart?
