Hi Rodskies,
There are few causes such as low B+ voltage, shorted modulation diode, shorted pincushion transistor, no signal to pincushion transistor. Without hands on assessment, I would not know what is the exact fault.

Hi Petes,

Do you mean the display tilted one side? If yes then possible the CRT Yoke already loosen and you need to unscrew the yoke and to a manual adjustment.

I have a TV with a spinned image, by that I mean that it's not fully horizontal so that the left part of the screen is a bit higher than the right part of the screen, the problem isn't very big but it's annoying, any idea of what the problem could be? The TV has no adjust potentiometers (or presets).

Hi Malik,

Did you replace with original L507 coil? How do you check that L507 is short circuit.
