I've found several bad solder joints on the neck board of my JVC 32' leading to the exact same issues as yours. Inspect the Driver resistor solder on the neck board.

JVC AV-32FA44 32" - No Picture, but sound OK

You could have a power supply problem as parts do go bad. Why your set faile is a mystery.. Of course if your not a technician, a TV set is NO place to be experimenting with. It only about a year old you say But get the papers on this set if you can find them and make sure as there is a 12 month warranty on this model. You should contact JVC At 1-800-252-5722 or online at Good Luck
