When I power on my KV-27FS100 I find green screen with almost horizontal zigzag lines. If I turn the tv off/on I see bright horizontal beam and within seconds whole screen turns to green with whiter lines. If I slap on top-left or top-right side picture comes perfectly and stays as long as I keep the tv on. As soon as I turn off the tv and turn on after 10-30 minutes , same problem happens. Also when the picture is ok, I see the right side color is distorted. What could be the problem?

Re: Green screen with almost horizontal zigzag lines
Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.

I would look for a Vertical circuit failure. Most likely is the vertical output IC and or open resistor off the hv transformer. Definitely look for any loose solder connections around the Vertical output IC.
Hope this helps,
Due to vertical section failure horizontal line apprears. You did not mention about picture. Green horizontal line means with picture or without picture. With picture means there is some leakage. Without picture only singe horizontal line means vertical section totally not working. Particularly green horizontal line means maybe leads to jungle ic failure. Please mention your simptom clearly what you get and what you will not get both video and audio. It will be helpful to answer. Based on your question this is my small information.
