Little update :

After a lot of work on the HV board, still nothing, so I decided to send it to someone who could find the issue and repair it.

The result is beautiful, better than a new one really awesome :spaceace:

Before





After it worth every $






In the meantime I installed a fan in the cockpit.



And try to fix the sound issue too find a tms5220 - speech synthesizer used in a few atari games  - with some broken leg but still no sound after socketed and replace, I do the same with the TL084"s on the pcb board. not better some popping sound sometimes it depends how was the pcb in the interconnect board.





So after power on still on color missing



Unable to find the settings with the pot to have all the colors without seeing vectors



At this point after all this time, I thought I had a issue on one gun on the Amplione, the green, and the only last solution was to try to rejuvinate it.  :evil:

Before I check all that I could. continuity, bad contact on main harness betwween the PCB and the deflection board and I went to Atariland to test my game Pcb in another Cab.. the PCB is working fine.
Still One color missing, by why me !!!!!

Last week I decided to do another test, I was advised to try is to modify the deflection board.

The purpuse is to swap two of the color signals. swap the red and green going to the tube, and if i don"t have green on the tube, the conclusion is there this is the tube.

So I must to lift the left sides of R67 and R68 and cross them



And ....



GREEN ::::: :spaceace: :spaceace: :spaceace:







Of course colors are not so accurate I do not touch the pot, I touch nothing to tell the truth.

So very good news finally it is not the tube, but I don"t know why and i am afraid of touch anything now.

New step yesterday, swapping back R68 & R68 and crossing finger to have all colors.



now I adjust the green pot.



Better now







I need to fix the top of my home made bezel and adjust the picture on the screen (X size) but the end is near !!!  :spaceace:

Still sound issue of course.
