ITEMS TO CHECK
The 2 very faint thin lines across the screen are normal.
They are caused by the aperture grille stabilization
filaments(Damper Wires) which are required for all
aperture grille CRTs'.
A brief vibration or hum sound that is heard just after power
up is normal. This is caused by the automatic degaussing
function. This sound will be heard each time the monitor is
powered up from a cold start and each time the manual
degauss button is used.
