You can find the remote control codes for different brands of devices from
http://www.hifi-remote.com/ofa/codes-tv.shtml#tv

If none of the codes work then we have two other solutions:

1. Searching For Your Code

If you have tried all of the set-up codes for your brand of equipment ,or your brand is not listed, and you are still not able to get the unit to respond, try the following procedure to search for your code.
If you don't find a code that works, the remote will flash four times when you reach the end of all the codes for this device type.

1. PRESS the button for the device you want to program, (TV, VCR, CABLE, etc.), then RELEASE.
2. PRESS and HOLD the SETUP button until the red LED flashes twice, then RELEASE.
3. ENTER 9-9-1 (two blinks on the remote)
4. ALTERNATE slowly between the POWER key and the DEVICE (TV, VCR, CABLE, etc.) button until your device turns off. (On VCR, LD, and CD players use PLAY instead of POWER)
   Make sure that the remote is pointed at your device during the search, You may have to press this sequences of buttons up to 100 times to search the entire library of codes.
5. When your device turns OFF, PRESS the SETUP button and RELEASE it to lock in the code for your device.

2. Learn the buttons from the original

Line up your original remote and the head-to-head before completing the following steps.

1. PRESS and HOLD the SETUP button until the red LED flashes twice.
2. PRESS 9 - 7 - 5, the red LED will flash twice.
3. PRESS the DEVICE key where you wish to learn the function. The next 3 steps must be completed within 10 seconds.
4. PRESS the button that will receive the learned function, the LED will flash rapidly.
5. PRESS the button on the original remote to be learned.

Now you can repeat steps 3 through 5 to learn other functions onto other keys or press and hold SETUP until the Cinema's red light flashes twice to lock in your new feature. (If the red light does not blink twice, stop and repeat steps through 6).
To test the new feature, press and release the device key in which the new feature was learned followed by the key on which the feature was learned

This is how I got mine to work after weeks of struggling just trying to find a new remote (hisense is really hard to contact....).
1) Turn the TV ON. unplug the tv while still ON 2) hold down the "menu" button on the side of the TV and plug it back in. keep holding it down. the TV should turn on with the menu popping up. use the Vol <> keys and Channel <> keys to navigate the menu. go to the Vchip menu, and play around. I'm not sure what ultimately worked, but i changed the Vchip password to 1111, turned the reset menu to "on" and played around with the ratings settings (turning most of them to "u"s etc).
I went through this process several times and finally, the black background behind the menu turned to static. I played around with the channels, and the TV was unlocked. I turned the TV off, and then on again, and the channels showed up normally (no static). and it was no longer locked. I had to do the unplug thing several times, and was getting really frustrated looking for an "unlock code" in the manual (it just says press the button on the remote. so it was not really helpful).
But really, once you can just get to that menu you've made some progress, and just keep playing around with it until something works.
Best of luck!!

I, also, have the Hisense LCD 1504 and cannot turn it on with the original remote. I have to use the ON button on the side every morning. You have to hold this button in for a while then wait a while and presto, the blue button shows on the front and the picture comes on. If it fails to work the first try, just try try again. It does work for me this way. We had this same experience with the TV in our room at a Hotel where we were on vacation and the TV worked fine when we turned it on using the side ON button. It just takes a while for the picture to appear. Hope this clue will help someone.

Are you referring to the iPhone/iPad app? if yes then this is not a remote app, it's a management app made for Comcast boxes and nothing else it doesn't controls tv's.
If you are referring to the actual remote for one of the Comcast boxes then it all depends on what model of remote you have and the exact model of your tv - some will support it thru the use of a Daewoo or Samsung code, others don't.
So you have 2 options:
1 - you try every Daewoo and Samsung code you have in the manual and if that fails you do a code scan on the remote as explained in the manual:
Turn on your TV
Press the TV button on the top of the remote, then press and hold Setup until the TV light blinks twice
Enter 9-9-1 and the TV button will blink twice
Press and release 1 and the TV button will blink twice
Point the remote at the TV, press and release the Power button, then press the CH+ button multiple times until the TV turns off
Press Setup once to lock in the code and the TV button will blink twice
If even that fails - the tv doesn't shuts down - then the remote is incompatible to the tv so
2 - you get a remote that is compatible with both. The only one i could find is
