Hi,

I have the same problem described here. http://home.c2i.net/tomcat/1209.htm
Now i checked the coil and it looks fine.
Is there any other component that could cause this ?

I'll give you a quick response. First have you verified its not a source problem. Put up an internal test pattern, if you have an all white or focus pattern. Are the lines still there. If so, it appears to be a horizontal problem. As far as saying what part it is, join the world of repairing electronics. You have to find the problem. Sometimes you get lucky if someone else had the same problem and can point you to there solution. Something like the other site you posted. And just remember, just cause your coil doesnt look fried like that one doesn't mean that its not bad. Happy hunting. Smile

I can repair it or swap it out with another board if you want.
