Something strange happens in this Philips TV

[Giulio Maiocco]

Hi Eckhard,

At the moment I don't have an EHT probe, so I don't know how much EHT I have... I think it could be very low, as I don't need to discharge the CRT when I have to remove the EHT cup, you don't hear the tipical sound of the CRT charging.

You could only see a very dim raster on the screen if you turn almost fully up the brightness and contrast control, otherwise the screen is completely blank... When you crank the brightness and/or the contrast fully up, you notice a blooming in the vertical direction.

I have the width control set to the minimum and the screen is completely filled in the horizontal direction....This tells me that the EHT is quite low, on mine I must keep the width control at the maximum to have the raster fill completely the screen...

Best regards

Giulio Maiocco

In these cases I have taken the high voltage from another well-operating set to test the crt.
