Take Apart CRT/Video Board - 58
Replacement Note: Raised lettering on the CRT socket
indicates the location of the focus wires. “Red” indicates the
lock for the red wire; “Black” represents the lock for the
white wire.
With the lock open, push the wire all the way in as far as it
will go. Close the lock and tug at the wire to make sure it is
secure. If there is any movement, open the lock and reinsert
the wire until it is securely connected.
