Silver Sony Wega 36" crt set has green screen

[zeno]

Video outs had problems. Some were 3 transistors in one case.
Shorted tube should give retrace lines then usually over
current shut down & a blink code.
Dont think its good green gun only. If so the AKB circuit
would cause blinking or blacked out video.
As a rule its not a hard problem to troubleshoot.
If you get it also resolder the vert out IC & check it good for cold joints.

Its your gamble. Its a beast to move. You also have to consider
what it may cost you to get rid of the carcass if its a junker !
