These tv units definitely have remotes when you first purchased them, if you lost the remote or broke it, ask the assistance of a tv technician for a replacement or compatible universal remote control. If you have a universal remote at hand you may try setting it but it will be definitely time consuming but it will be the only way to fix your problem. Here's how: On the universal remote , follow the instructions on how to set the remote, but this time when asked for the 3 or 4 digit number code you will be starting from 000 or 0000. then gradually add 1 to code such as 001 or 0001, continue adding until you come across a combination that your tv or the cd-dvd unit will respond to, write down these numbers and identify to which device on tv it responds to, then continue on until you get the codes for the whole system.....it may be redundant or time consuming but this will be your last resort if ever you still want to use that TV, if unit is returnable to where you bought it , dos so return it and buy one unit with a remote...

Buy a used remote from ebay, max $20.
