Will hoovering inside my tv bring final my blue shaft of light inside the tube?
Answers: Hoovering it will most plausible cause SHORTS to go on, then you'll really hold some major problems !
A loss of blue could be simple, resembling the screen control adjustment, or an start heater circuit.
Get it serviced by a qualified TV
It is extremely unlikely unless there is some loose conductive textile shorting out the contacts to the blue cathode on the cathode ray tube.
What you necessitate to do is take the TV to a TV technician who can adjust it for you and make clear to you if the tube can be rejuvinated to make the blue gun work again.
Two possibilities here !
Could be blue gun low rays but usually in that satchel there is still some blue.
Not Cathode short as this turns blue FULL ON not OFF Mr Broadcast.
Only one space heater for all three TV Tech !
Correction three fillaments within series ! Loose one loose em all !
Most possible the blue video amp transistor has spoilt or anything in the blue video tie up leading up to the Tube.
Best course of behaviour !! take set to w/shop for an estimate .
PS Hoovering will be futile !
