hi i have a problem with my tv there was no picture nor sound, when i took out the resistors r241 and r242 and replaces with one other resistors which i had, the picture was there as well as the sound. but picture had horizontal lines over it and kind of enlarged when changing channels, also when i press menu button the picture enlarges a lot and is hard to see you know what the problem might be? thankss would anyone have a schematic? thankss
