Tektronix 2236 Powers On but Nothing on CRT Screen

[happylife5678]

I just got my first scope it's an old tektronix 2236 scope, it powers on, power led and a trigger ready led lights up, but I don't see any lights on or around the CRT tube screen. Is there a button/dial for the screen to light up? The multimeter reads 60.000xxx also. Please help!!!
