TV - only single, linear image with sound

Question

hello fixya,Stumbled on your website and am hoping you can help me.I bought a TV from KMart in May 2005 (hence warranty expired May 2007). It has always worked well until last week. I turned the TV on and i only saw a single, vertical line on the screen. The sound is working fine.Can you tell me how i can fix it?LeeMelbourne, Australia
