I just bought a, insignia flatscreen (NS-20CLTV)...clearance, on display from bestbuy, so I didn't get the original remote, they gave me some rca universal remote. I have gone through so many codes my head is spinning and nothing has worked. I can't do the "learning" thing because I don't have the original remote. I don't know what to do, I can't turn it on/off, or anything. I don't want it for directv or anything, I just want it for tv/dvd use like volume, channel, input, on/off. Why is this so complicated? Please help.
