I can't find a remote code for my Insignia 39" LCD TV. The model number is NS-39L240A13. I have the silver remote with the red OK button. I have tried all of the codes listed and none of them work. I even tried to find the code manually but I kept getting one long red flash after putting in the code. I found a code that works for the AUX button but it won't work for the TV button. Please help!
