Removing HV / Power supply board.
Remove metal bracket from HV transformer.
Remove plastic holder along back edge of PCB
There is a red key going through the PCB near
some connectors. Turn & remove.
Remove edge connectors & 4 or 5 others on top of PCB.
Unplug anode, focus & ground straps.
Push down on 2 plastic stops at the ends of the board
& pull out........
If the board has been out before often the key & holder are missing.
That board gets LOTS of cold solder. Go over it good.
