There are two possible causes for this problem, either back light inverter board stop working thus screen goes black as lcd screen needs back light to show its image OR if sound remains while screen goes black then it seems firmware issue.
Let me know is it Insignia NS-LCD42HD tv or any other model?
Do you get sound in tv while no picture?
Does screen show any on-screen display when tv lose picture?
Above info will help me to diagnose problem in tv and to suggest some solution.
