this is an error when the back lights fail to work five times (until the count is zeroed). You might get luck if you press the [volume down] and the [input] on the TV keyboard then press the [power]. Once the indicator turns green then release the buttons. If it comes on then the TV section might be fixable.
Every time I have worked on this error it's caused by the "main" board in the display section. This board is not available as a new board, it must be sent in to be rebuilt. The cost for the part repair is over $500 plus labor to install. I did find a harvested board (I have not had any luck with these boards): http://www.encompassparts.com/item/8502950/Green_Choice/DUNTKB453FE04/Sharp_Duntkb453fe04_Main_Board_For_Lc-37hv4u
