I have a rather old Sharp Linytron that was made in the late 80's, model #25NC158. I salvaged it from some relatives that had it sitting in storage for some time. The problem is that I do not have a remote and can't seem to find a code that works for the television. I have a One For All remote, model 4021. Does anyone happen to know the code for the television or a good web site that I may go to in order to find a list of codes that might work?
