Greetings group. Philips ctv model 25GX1886/75R. Tv fell off its perch face first onto the floor (around 40cm).
Power switch assembly had been dislodged. After remounting the switch, ctv still would not turn on.
With the help of a magnifying glass, I found cracks through around 18 tracks which were repaired.
CTV now turned on, but the picture could barely be seen through many vertical red/green/blue stripes right across the screen. Sound is fine.
Shorting each gun to ground did not produce only a red, green or blue screen. It only changed the strips slightly.
I suspect the shadow mask has moved inside the picture tube.
What do you think?
Thanking you, Russell Griffiths.
