TV won't turn on

To try to offer some help I need to know the full model number of this set.

did you try new batteries in the remote? if the tv has buttons on the side and one of them being power di you try to push that? did you push tv power or cable power holding the buttons longer? those things might work.

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, Mr. Ross.

I'll be more than happy to assist you with this and all of your other Uverse concerns.

First please write these codes down, these are the TV codes for your Mitsubishi TV,
0093, 0150, 0178, 0019 (we are going to do trial and error for these codes till we hit the correct one for your TV.)

Please turn the TV on and point your ATT remote control.
Okay, using your ATT remote control, please press and hold the TV button together with the "OK" button.
All four modes should flash twice indicating that we are programming your remote control.
Now, enter the 4 digit code and the selected mode (in our case it is the TV) should give a long flash.
Then press OK.
Try to turn your TV off and check if it would respond
If not, please redo the steps but this time use the other codes I provided earlier.

If these codes wont work we will do the automatic code finder if you are using the "black" AT&T Uverse remote control.

Using your ATT remote control, please press and hold the TV button together with the "OK" button.
Then press the "scan/ff" button repeatedly with atleast 1 second interval till it turns your TV off.
Press OK then try to turn your TV on again.

Whenever your remote won't respond, try pressing either the AT&T button on top of the remote before any other buttons or the TV button beside the ATT button.

You were attempting to perform a power scan initially. The second procedure is manually attempting to address the remote to your TV. I will give you the procedures again so you can try one more time. Emerson TV is one brand we have a low percentage of success getting our remotes to work. If it still doesn't work, we could try replacing the remote.

TV code: 623, 667, 666, 233, 516, 537, 544, 642, 655, 699, 000, 999, 888, and 720.

Remotes: Basic (Television Only)

1. Turn the Television On.
2. Press and hold the clear TV button for six seconds until the LED flashes.
3. Enter the three-digit code using the buttons on the number pad.
4. Press #. Note: The LED will flash three times.
5. Test functionality with the TV.
6. Return to Step 2 if the remote is not able to turn the TV On/Off, change the volume and mute the television.

Remote Power Scan: Basic Remote (Television Only)

1. Turn the Television On.
2. Press and hold the clear TV button for six seconds until the LED flashes.
3. Press and release the red TV Power button.
4. Press and release the Up or Down Arrow on the remote until the television turns off once every second.
5. After the television turns off, press and release the # button.
6. Test functionality with the TV.
7. Return to Step 2 if the remote is not able to turn the TV On/Off, change the volume and mute the television.

Good day.
Please check with the channel buttons of your unit. They replace the power buttons functions.

Does the same thing happen if you turn it on without the remote?

If not, it's likely a short in either the remote or the sensor on the TV that receives the remote signal. A short in either would break the power on signal into two separate signals, which the TV would interpret as you hitting the power button twice, and would thus turn on and then immediately back off. If that's your problem, I'd suggest getting ahold of another remote for your set, or a universal remote that you can program for your set. There's a good chance that will fix it, and it's much easier than trying to fix the sensor.

If the same thing is happening when you use the power button on the TV, we have an entirely different problem, most likely a short somewhere. The power supply detects the short and shuts itself off to avoid doing more damage (or causing a fire). Sort of like how a circuit breaker works. That would explain it turning on and back off immediately. If that's your problem, you'll have to have someone who's handy with electronics take a meter to it and find the short. How you fix it will depend on exactly where the short is.
