We have a 22" Polaroid flat screen combo TV model #TDAC-02212 and the remote IERC03 does not work. Can I get another remote - the TV works with the built-in controls.

Use code search on your GE URC to find something that works. You may need separate codes for TV and DVD player. If a search through all codes stored in the URC fails, try a different one.

Check the remote control for its infra-red emission. Check it with fresh batteries. Check by pressing all the buttons on it; and see whether all of it generates infrared signal while pressing. If it is found OK, check and replace the infrared sensor inside the TV. If you wish to get some details; check the site linked here. It has details about how to check a remote control; by one among the post. Surf the site with patience.

May be suitable for your model; it is nearly identical.
Also, try contacting the maker directly.

should be under warranty but the remote itself can be tested by any shop--also some digital cameras when remote pointed at them in a dim room will react on their display screen with a flash when remote pointed at camera and buttons pressed on the remote.
