Re:
Sounds like a bad connection on or in the vertical output circuit, or the drive circuit. Could also be the vertical output IC or the surrounding componets going bad. Good Luck

Hi there! If picture is smaller top to bottom with blank section on top and bottom then check your aspect ratio settings. If blank at the bottom only the Bottom Y-Drive board may be faulty. If blank at the top The Top Y-Drive may be faulty. If blank on the Left (TOP TO Bottom) then the Right X-Drive Board and on the Right, the Left X-Drive Board. May also be bad connections on the cables or flexible ribbon cables. Best Wishes and Good Luck, JUS004

When only a half screen is produced, it is usually a upper or lower buffer board, if the top half is blank then it is the upper buffer, and of course if it's the bottom half then it's the bottom buffer board
