Steve,
If you have the means, you might try removing the two side screws, knurled nuts over phone and key jack and separate bottom cover. Remove the battery for 60 seconds. Put it all back together and set the cw vox back to 300ms our so. If that doesn’t work you may have fried the display? 12 volts max i believe.
