Nanao MS-2931 Chassis Problems

Put everything back together and still nothing.

The monitor sounds like it is coming on from the neck area in back.  You can hear pop/static/ting.  But there is nothing on screen.  Not even any static electricity.  I am out of ideas.

If you crank up the screen on the flyback can you get a raster?
clutch:
tried that. nothing.  screen looks really dead.

I figure the chassis is good because I hear the quick pop/static/ting which I didn't before.

is it something shutting off like a protection circuit?

Update:

For clarification, I'm trying to get the 2931 to work again.

I have a WORKING 2933 chassis and tube.  I did a swap.

The 2931 'repaired' chassis with the 2933 tube exhibited the same symptoms.  Static/pop/nothing.


The 2933 chassis with the 2931 tube worked like a charm.

So...something is preventing the repaired 2931 chassis from powering up the tubes.  I guess that is fairly good news in that I now know my 2931 tube isn't in the sh#tter.

This is soooo fun.

I'm taking pics along the way, so once I'm done, I'll do a whole chassis swap tutorial with a 2933 and 2931.

what about neck glow? is the heater coming on?

after the initial crackle can you hear anything... flub flub flub or tic tic tic?

can you put a meter on the B+ line and see what it does on startup? spike up then fall off or nothing at all...
