Hi @jk5563 ,

Here is a link to the Bose 3-2-1 service manual which should be of some help as it has the all the tests and circuit diagrams of the unit.

To download the file when the sentence below the Document preview box changes from This file is downloadable free of charge: ...processing... to This file is downloadable free of charge: Get Manual click on the Get Manual as this is the download link. Be patient it takes a little while to find the file.

On p.42 and p.46 and also p.64 it describes how to test the display panel

If you find this too daunting, I suggest that you contact a reputable, professional electronics repair service (preferably skilled in audio receiver repairs) and ask for a quote to repair the unit.
