I have no ''tv/catv'' button on my Philips universal remote

I don't think you will get that to work, you have two units in one box

'Z11' doesn't seem to be the correct alpha numerical model number.

phillips universal remote with orion 1326 tv.
ned code

Lost my remote codes for my philips remote. I need the combo codes for a tv, vcr,and dvd.

YOU CAN USE EMERSON CODES FOR YOUR ADMIRAL TV AND TV / VCR COMBOS, MY COMCAST REMOTE ACCEPTED 11911. SOME REMOTES NEED FIVE NUMBERS AND MY ADMIRAL ONLY HAS THREE. SO I USED AN EMERSON CODE AND IT WORKED MOST OF THE BELLS, NOT ALL WHISTLES WORKED BUT I DIDN'T HAVE TO GET UP TO TURN IT ON, CHANGE THE CHANNEL OR THE VOLUME. MY KIDS WON'T DO IT ANY MORE!!
GOOD LUCK!!!!!

The code for the TV is 0623 but to use the TV/VCR button to change mode from line to TV the code is one of the following 0179, 0451, 0463, 0624 or 0278. The 0623 only activates the menu but doesn´t let you change Air/Cable mode without first changing the Line/TV mode by pressing the TV/VCR or Line input button on your universalk remote with one of the other codes.

Try www.remotecodelist.com .........T.

Go to http://www.jvcremotes.com/ or any similar site and order the original remote. That way you are sure to get a remote capable of doing whatever you need. The alternative is to keep buying universals until you get lucky and find one that works all functions on that set.

I had this problem with my TV/VCR combo unit (Samsung CXC1972) after losing the remote while in the dorms. I tried a few different universal remotes and dozens of codes before I tried the Philips 3 device universal remote as pictured below with code 037 programmed into the VCR/DVD button. I can't change the volume with this code but the input key switches between line in and tv. You can also change the channel, access the menu and operate the VCR functions with the code. I bought the remote for less than $10 at Walmart so it might be worth a try, and if it doesn't work you can always bring it back. Hope this helps.
