those with extensive #crt repair experience:

i've got an Amdek V232A monochrome (amber) crt. the power light comes on, but there is no 18khz whine, no static on the glass, and no picture even at full brightness/contrast.

what would your first/most obvious troubleshooting locations be?

i've done a lot of crt pcb recapping and a few flyback transformer replacements/reflows, but i have zero diagnostic skills when it comes to crt design

thanks in advance for the help
