Q5A20 and its associated circuitry comprise an Arc Protect circuit. If a CRT Arcs this circuitry immedi- ately removes HV Drive.

If X-Ray Protect shuts the TV Off, pressing the Power button will turn the TV back On (it may shut Off again if the problem still exists). If Arc Protect is activated, the TV must be switched Off before it can be switched back On.
