Have 2 x G05-801. One is working and one has no HV.

The non-worker has a slightly different HV PCB layout compared to the working one. The working HV (and the rest of the boards of the monitor) seems to compare to "issue 1" of the manual and maybe versions above that.

C902 on the working board is a tantalum capacitor @ 100uF (according to "issue 1 manual" whilst on the non-working board, there is a 22uF capacitor on the parts side and one on the solder side (2 x uF), but there are other differences of the layout as well. I have isolated the problem with the high voltage to the cage since when I swap in the other HV cage it works. I've tried switching the HV doubler between the cages without success as well as the 2 x chassis transistors on the HV cage has also been swapped with the working one.

I've also replaced the 3 electrolytic capacitors, C901 (47uF/50V) was open circuit.

Game board is working, spot killer is off, chatter is there, neck glow is there.

The black and white vector/x-y guide mentions a "preliminary issue of the G05-801 manual, anybody who has scan of that or a link?

The input voltage of +25V is there on the connector of the HV cage but the other voltages are missing (like +90V, +400V and focus voltage) and they are present on the working HV cage.

Measured +25V at base of Q900 (+18V on the working board).

+9V on the anode of ZD900 on both boards.

Ideas of what to troubleshoot next is appreciated! :)
