How to tune hisense tv without a remote control?

SOURCE: i need a new remote control for hisense tv flat panel, where can i buy one?

I've had very good with the Radio Shack Universal Remote. It recognized everything I had. Try that, because if it doesn't work, you can take it back for a refund.

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

follow the power cord inside the set and to begin with look at the fuse which the cord goes to--also inspect to see if puffed up caps in the power supply----see attached photo
