The only vendor for this would be sharp or a authorized parts dealer. The cost of these LCD panels usually makes the repair senseless. You may get a cost estimate from sharp at 1800-besharp.

Hi,
If tv is under warranty then call Sharp or Store to provide warranty cover because it seems lcd panel has started problem by showing intermittent horizontal line and this problem will increase.
Solution is replacement of lcd panel and its price is approx 80% of new tv so warranty coverage is needed to get it fixed. Check warranty documents of tv and give call to Store or Sharp.
Thanks.

I've seen a similar looking problem and it is a bad LCD panel. It will show even on a non-used input, and will show through the menu screen and the screen saver, also. Sharp's LCD panels are very expensive,too. Over 4000 at encompassparts.
