I have replaced the WB27X10858 Display Control Board thinking that might fix my problems but no real change. We have been having the screen flicker and show random glitches but still functioning. Today the screen is locked up on “push start for more” and is unresponsive to pressing any of the buttons.

Hello, glitchy displays are always hard to pin point. I can recommend going over all the connections with it plugged in and CAREFULLY checking to see if the issue changes when you touch certain plugs or wires. if you are not comfortable doing this I understand. You may want to contact a local service company and let them investigate. Anything beyond doing this is just a guess, and a expensive guess at that.
