Hi there,
Dynex TVs can have different remote codes, depending on the model of the TV you own and the type of remote you are using. You didn't specify your specific Dynex model number, however the company only makes one 15" HD TV model. It's therefore quite likely that you own model DX-15L150A11. Even if that isn't the exact model you own, the information below should apply to all 15", 19", and 22" Dynex TV models.
Below is a list of the most common remotes, along with the corresponding IR remote code for your TV.

If you are a DirecTV or Cox subscriber, you may sync a universal remote to your television using code 1548 or 11548.

These codes are for use with the following Coby television models:
TFTV1022, TFTV1212, TFTV1513, TFTV1514, TFTV1524, TFTV1913, TFTV1923, TFTV2214, TFTV2224, TFTV2617, TFTV3217, TFTV3717, TFTV4717

If the codes do not work, or if you are not a DirecTV or Cox customer, the universal remote control manufacturer is responsible for creating and embedding a Coby-compatible code in the remote control. Please contact your cable carrier or the universal remote control manufacturer for assistance.

For the Direct White remote it is 10178
