What is the remote control code for a Symphonic TV model number CST247FE?

Which remote control? A number of outfits post online different codes for different remotes for different sets. (Hope that made sense.) Try programming the remote to operate another set other than the Symphonic. If the remote works, fasten your seatbelt. Here's why. There are still a few "hard-headed" manufacturers who make sets that have remotes with "oddball codes" and they cannot be replaced with the universal remotes. Some Symphonic sets are like this. Buy a remote from a company that will take it back if it won't program to your set. Ask them up front about returns. Radio Shack is one such company that will take the remote back if you cannot make it work with your unit and you return it with all the stuff it came with - including the receipt.
