Depends on what that 5 incher is you are trying to use, you have not said what it is yet, if 5kv is below what it needs to have a full raster with full scan at normal operation, then obviously you won't see anything, and in phono mode, brightness is cut no matter what.

Did you unmount the focus coil? It interferes with the 5AXP4 focus

No I’ll do that

Or at least move it around as see what effect it has. Also do NOT use the ion trap magnet. You should get a glow on the CRT with 5kv

Removed the focus coil...did not have the ion trap on it and there's no change. I hate to keep coming back to this switch but, I measured the voltages on the brightness control (working...ohmed out 10 ohm to 52 Kohm) with the switch in the TV position and I turned the brightness control through the full range while measuring the voltage on all three tabs and had an invariant 135 volts DC reading. No change on the brightness control voltages.

Here's this area:

what are the voltages on the other pins of the CRT G1 and G2? you say cathode is 135 and wont change?

Short #3 on the brightness control to ground and try

yeah. go for broke! :D

that will force it full on! or at least pin 2 of the brightness control should drop to near zero when you turn it to that direction if it's good.

That did it! I have light on the screen. No horizontal deflection but there's a line down the center that responds to the brightness control.

I'll get the voltages on V19 from pin 6 of V18 in a few.

Thanks guys. You Let There Be Light!

OK the voltage weirdness is as follows. Black lead from DMM on pin 6 of V18 6SN7GT Horizontal Oscillator and voltages on V19 6BG6 Horizontal Output

Pin #: 0.0V
Pin #2: 0.0V
Pin #3: 4.6V Should be 8V DC
Pin #4: 0.0V
Pin #5: -10.0V Should be 8V DC
Pin #6: 4.7V Should be 110V DC
Pin #7: 6.3V AC
Pin #8: 240V DC Should be 260V DC

There's a jumper installed on V19 between pins 3 and 6 on my TV. Is that supposed to be there? There has been some fiddling with this TV over the years. Why isn't pin 6 over 100V DC?

No horizontal deflection but you have high voltage?!? That can only happen if the horizontal yoke is open or not connected.

Well there's good news. Tube is correctly oriented because when I adjust height, the line shortens in the vertical aspect. I'll check the connections.

The fact that you have HV, vertical sweep but no horizontal is an indication of a possible problem with the horizontal yoke windings and the path from it to the flyback. al that must be check very closely for it;s a tuned circuit, and when it gets out of wack you are lucky to get any HV at all, the fact you have vertical sweep but no horizontal is a big pointer in the direction of the problem, I dont see where it's stated that the resistance of the horizontal part of the yoke should be, but it has to be someplace, that is a good place to start.

13.5 ohms. I will check

15 ohms on the horizontal yoke. I measured from pin 6 of the 5V4 damper to the other side.
