Hi: I have a Hitachi Remote Controlled t.v., for which the remote has been lost. It's Model # is CT2o75W and it's from 1988, but works very well. I need the codes for the RCA Systemlink 3 universal remote. I have tried using the search code method for the t.v, and it accepts 006, however, it won't turn on and off or channel change after the code is put in. Also, my cable company is AT&T Broadband, for which I don't find codes for, but have tried using a standard component code of 039, which it accepts, but again, won't work with the remote. After entering the codes that are suppose to be for the t.v., I get three flashes on the remote, indicating it's acceptance, but it still won't work. can you help? Thanks.
