I'd be more interested in the .01 mfd across the sine wave coil. That determines the horiz frequency.

The .0015 you refer to is that the .0012 to ground, was that a typo ?

The sine wave coil on the schematic I have from ETF shows that coil as L155 unless there is another listed as L16 . The .01 cap across the sine wave coil I changed already with no improvement and I checked the coil it is not open. So it won't be easy to watch 3 images , lol . :no:

It was supposed to be .0012 . It was a typo!:scratch2:

So I did use Micas for the .0012 cap which equals 1201pf and still I have the 3 images and the sine wave coil after turning Alittle bit had no affect unless it has to be turned several times. I also checked the 6.8 meg resistor at that coil not off that much.

All times are GMT -5. The time now is 05:08 PM.
