Originally when tv is on , blue screen with blue and green dome lines appear
on the screen.
Then, when blue crt board pulled out, green screen with green dome lines
appears on the screen.
And finally when blue and green crt boards are pulled out, nothing appears
on the screen. The screen is completely black.
