You can program your GE universal remote to work with most televisions without the code but there is a procedure that needs to be followed.
First, turn on your TV and press “Code Search” until you see an indicator light.
Next input this information using the number buttons on the remote (1-6) then select Set Code by pressing Enter or OK after each digit that appears under Settings - Programming Channel Number(s).
After saving all numbers into either Codeshare mode if there are two codes available for one particular manufacturer/model set-top box cable receiver converter etc., wait patiently before testing out whether they worked!
