The actual display CRT is bad. These are custom input conventional CRT displays that can only be repaired by an electronic Tech. These displays were actually made by ZENITH. I had the same issue but just popped my 1986 CRT into my 89. They are very easy to change. I can buy one at the local junk yard for around $40. Intresting factoid - These displays are upwordly interchangeable BUT NOT DOWNWARD. A 1986, 87, 88 display will work in your 1989 but not the other way!
