Got another chassis ready for testing today.
Hooked it up, turned it on... no smoke... so... yay that.
But I get no picture. Brightness on the chassis itself and flyback do nothing to bring up any raster... I get no brightness control what-so-ever.
I checked Fromms flowchart... and got to the magic dead end of the flowchart... Voltage checked fine... no raster... heater is glowing... ... ... the end. That's where it stops.
I got the chassis in a bulk deal because the board was cracked. I've repaired that, fixed every trace I can think of... but I still can't get anything up on the screen.
The flyback doesn't show any signs of past explosions or anything like that... seems to be pretty sound. I'm just not getting anything on the screen.
I DID notice that the neck glows blue... there's a very light blue glow. I haven't noticed that before with the regular chassis that goes with the tube, but I just haven't really paid much attention to it... The heater still glows normal "heater color".
Anywho, any more ideas on where to go with this guy?
