Important: These transistors must be replaced in pairs. After replacing the above transistors, use
your DMM set to Ohms and check the continuity between the metal monitor chassis and the metal
case of the above transistors. If there is continuity (zero ohms), you need to replace the thin clear
plastic Mica insulator that goes between the transistor and the monitor chassis. There should be NO
continuity!
