TV not responding to the remote control. Remote won't turn tv on. Tv has power as does remote.

try switching on tv point remote at the tv pressing the menu/exit button and holding for 10/20 seconds hope this works for you

If set turns on with the power button on set the remote is : not set to TV, not programmed for the set, has bad batteries or is bad.

If it even works one function it may need to be reprogrammed or taken apart to see if works---you can test the remote by pointing it at a digital camera with a LCD screen and pressing buttons to see if it makes the screen flash on the camera.

Test the remote first

Hello
There is a infrared light sensor inside the TV which detects the infrared rays emitted from the remote control, when we press each button on the remote control. If this sensor has got damaged, the set won't respond to any remote control handset. The sensor can be located just behind the infrared sensor window at the front panel of the TV. To access it, you have to open the TV. It is a three terminal component, will be soldered diretily to front panel circuit board, of with the main baord itslef. Will look somewhat brownish black in colour. There are so many types can be seen . Just look what type if fitted with your TV.
See some models infrared sensors. Check out which type your TV has.

leave the tv disconnected for a while because if you keep messing with it like my kids did and it will cause the bulb inside to burn out and will not even be worth fixing

Universal Remote Control Simple Setup

* Point it at a TV set and press the Mute/Power button. (Mute button if TV is already on, or Power button if the TV hasnt already been turned on)

* Keep pointing it at the TV until the TV turns on or muted, most TVs respond in about 5 seconds, the most is up to 20 seconds. (Other universal television remote you find in stores take minutes to program and enter long confusing codes)

* Once the TV is muted or turns on, simply let go of button and you have total control. You can use the remote as if you had the original remote, and responds instantly. ENJOY YOUR FREEDOM of choices with our remote!
Most remote controls require minutes of programming a universal remote code into each television while you read the confusing instruction manual.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

DON'T FORGET TO RATE:

Unplugging my TV for 15 seconds (longer actually - at least a minute) made the remote and the satellite TV remote both work again with the TV.  Thanks for the tip!

1) Turn on TV;
2) Press TV on the remote control;
3) Press and hold SETUP, until the red LED indicator blinks twice;
4) Enter 9-9-1-1 on the numeric keypad;
5) Press POWER on the remote;
6) If the TV doesn't respond, repeat #3, #4, #5.

I have the same problem. When I move the 8300HDC away from the TV, or power off the TV, the remote responds. There seems to be some kind of RF interference, which makes no sense since the TV shouldn't emit RF, and the the box should be using IR only for remote input. My TV is a 46" LCD Samsung. Try turning off the TV and see if the 8300HDC responds to powering on and off with the remote.
