Hi:
Try this. turn on tv manually. press & hold CODE SEARCH button until light stays lit.
press TV button. press POWER button repeatedly until tv turns off. THEN PRESS THE "ENTER" button on your remote. this same system works many devices(vcr,dvd,sat,etc.) for those, you'd press, lets say, VCR button, whilevcr is on, and then repeat the above stuff (yeah, pressing the POWER button on remote MANY times can be boring, but it will eventually turn off vcr, then hit ENTER button on remote)
repeat for each device you have, changing only the device button on remote for different electronics. good luck!
