There are no indications that the flyback is shorted and you have a stable B+ and a good HOT so it's time that you connect the chassis to the tube and check the voltages that come out of the flyback.
This is what I gathered from examining your pics:
Pin 1 connected to + of electrolytic cap (- to ground) is unclear especially since the cap is rated 200V and there are no voltages that high on the secondary side of the flyback.
pin 2 flyback pulse/AFC to pin 13 of sync/V-H oscillator IC (a clone of HA11235)
pin 3 (heater voltage 6.3AC) to neckboard.
pin 4 (25V?) to vertical deflection transistors.
pin 5 (12V) to pin 6 of sync/V-H oscillator IC (a clone of HA11235)
It's unclear what pin is ABL (the other end of the EHT), either 1 or one of the grounded pins.
Check if you have something from the flyback pins. Not directly on the pins, the voltages become DC after the diodes. There are handy points on parts side if you follow the traces.
Hi
Just an update to this old post.
I have used som hours trying to fix this chassis, but without any luck.
I have solder in all the missing parts, and connected the chassis to a monitor to test.
There is only 6-7VDC at the middle leg at the HOT.
I have noticed that sometimes the HOT model BU2520DF blows.
In my mail from when i contacted min-dong about replacement parts they wrote that a BU2520DF or a 2SC5539 wold be a replacement for the HOT.
I have also the 2SC5539 so I have tried to put that in, It does not blow but the B+ is still 7-8VDC at the middle leg at the HOT.
If I remove the HOT and de solder the 200V 100UF cap from pin1 at the flyback, I can measure 115V at the middle pad at the HOT.
So my conclusion is that it must be something with the flyback...
But when i discharge the monitor, I get a big spark, so the flyback must be doing something...
Well.. I have to realize that maybe this china chassis do belong in the "unable to fix" but it will then be the first thing that I where unable to fix, also with all your great help
