Trying to get my directv remote to control this TV

slide the mode switch to tv, hold down mute and select until the light blinks enter "9-9-1-------1" when the lights finish blinking start pushing push the channel up button. this is a code search. It will transmit every code it knows one at a time. when the tv turns off you've found a code that works. turn it back on, try the volume and see if it works correctly. when finished press select.
most tv/dvd and/or vcr combos won't work with tv codes.
Directv has posted many new codes on their website for combo tv's Go to [ www.directv.com/remote ]to look up the latest codes read the programming section for the remote as there are many customizable features on the remote that most people aren't aware of. good luck
