I have 2 EZ 20s doing similar things. No power.. Verified voltage in, not blowing fuses. One is showing an open hot but why are they not blowing fuses? I guess maybe I am new and flybacks or HOTS dont take out fuses? I tried flowchart but again no fuses are blowing. Tube is just black, no raster at all. B+ is showing a whoppin 7.5volts.

Am I tired or missing something?
 
An open part wouldn't blow a fuse, the complete opposite, actually. Shorts blow fuses.

Start going through the power supply section. Double check to make sure that the fuse is actually okay. You might have to pull it to verify with a meter. Don't rely on your eyes.
 
Test the diodes in the power section D601-D604 IIRC

Dokert yes you are correct. All Diodes check out in the power section, fuses have been checked by meter prior. Is it any clue that this is a DK cab and there is no sound either?

Thanks for the hands on fun!
