i have had this tv for about 3 years now. about 3 months ago i lost the video but not sound from the front inputs(the only s-video input) i switched reg. video input on the front inputs and still had no video but audio was still ok. i switched to the video and audio inputs on the rear and it has worked fine for the last three months. today i turn it on and guess what?  NO VIDEO!! audio still ok. i have looked for similar issues all across the web but have found no symptoms compareable to mine if anyone has any input it would be much appreciated, i really dont want to have to buy a new set.
