There should be a green dot on the screen when powered up. I think the CRT is dead. It may repairable but I wouldn't take a chance as it may be an unobtainium made part.
Good call since the brightness control is turned up quite a ways. I have one of these & replaced the CRT with 4FP7 CRT. Dual phosphor with blue short persistence to show where the sound is, green phosphor to show where it was. And the CRT is flat face.

Cool! I may have to look into finding one of those CRT's. Mine works but has a significant amount of burn-in around the center point.
