SOURCE: TV will not turn on

Ok, you stated that you get a green for a second and then a couple of blinks and then, it turns off. This rules out the power board but, its main control partner is experiencing some trauma. Normally in the plasma TV set, the green is a go but, if the PCB(Power control board), doesn't agree, the the power board will shutdown the entire unit after giving a few blinks. Its very important to remember that, the power board and the power control board are two separate circuit boards. In your case, the PCB is down and it will need to be replaced.

Please rate and god bless.

SOURCE: The tv will not turn on with either the remote or

Hi, I own the same TV and had the same problem. It's the #1 plaguing issue with flat panel TV made by Funai corp. Emerson is made by them. Normally, when this happens, the TV goes into " Protection Mode " because of a failing circuit board.

The most common thing to go out on flat panel TVs is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board. But, I can't say it's 100% the problem because I can'tactually look at the tv over the internet. I can only make guesses with the symptom. I'm willing to bet you have the same problem like mine. One of six Inverter Transformers when bad on my Power/Backlight Inverter Supply Board. I replaced it and it works fine again.

You have a few choices:

1. You can try leaving the TV unplugged for 30 minutes so the TV can reset itself.

2. If by chance the TV is still under warranty, go that route.

3. If you have some electronic experience, if you can find and purchase a Service Manual at; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists.Usually, cost under $6. And most cases the new part cost less than $15. The service manual at the site is under LC320EM82S.

4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.

I hope I shed some light on the subject for you.

It appears like the 5VDC is low from the power supply adapter. This voltage becomes low due to defective capacitors inside the power supply.

Can set up th remote control for this tv with the direct tv cable remote

Here's how to scan for TV codes on your DIRECTV remote

1.Make sure your TV is turned on.

2.Slide the mode switch at top of remote to "TV".

3.Press and hold the MUTE button. This is located above the number 1 button.

4.While still holding down MUTE, press and hold the SELECT button until green light at the top of the remote flashes twice.

5.Then enter 991, the green light on remote should flash twice.

5b. Press 1 again (it will flash twice again), then you press the power on button at the very top right.

6.Point remote at TV and press CHANNEL UP button. Tap the CHANNEL UP button repeatedly until the TV powers off.

*If you hit channel up very fast, you risk going past the code. Pressing channel down will back it up. I alway hit channel up very fast till the tv turns off, then back it up slowly till it comes back on.

7.When the TV powers off, press and release the SELECT button.

*Note: If the green light flashes three times before TV responds, then all codes have been cycled through. Our remote controls are guaranteed to program to your DIRECTV receiver, however your TV may not be compatible with our remote control.

Well my mom was watching tv and it just shut off so then my mom turned it back on thinking she might have hit the power button accidentally. But when she turns it on it started blinking the green light for...

The flashing light red power light should only stay while the fan cool down for about 1 minute after a power off (remember to always wait before unplugging the TV so the lamp can cool down with the fan). Does that flashing start right away after plugging back the TV after an hour of letting it without AC power.

The red light should flash no longer than 10 sec. This prepare the light to be turned on. If all is OK the green should stay (no longer flashing) and the sound and picture come on.

As for the lamp flashing, i bet it's only 1 time each 5 sec? Or do it group many rapid flash each 5 sec?

Things that can be wrong:
-the fan lamp

-the lamp is not proprely inserted (wait an hour before manipulating it to be sure it cooled down, and use glove to not put body oil on it).

-Lamps is defective and is not operating properly so you can't get to the usual on screen message that recommend to change the lamp.

My Sabre LCD TV is blinking red and green on power button and will not come on

My TV just did this 2 days before Thanksgiving. I just messed with it and fixed it today. Unplug it from the power source for atleast one hour. Plug it back it. Hold the power button til constantly flashes red and green. Wait at least one minute while it continues to flash. Turn it off. Flip the big power source button on the back to off && then on. Then hit the power button on the side, and it should turn on. Worked for mine. Hope it helps.

My flatscreen emerson tv will not turn back on.

I found a way around this problem. When this happens, don't use the remote.

Walk up to the TV, then HOLD DOWN the power button and while the lights are flashing, start pushing the menu button on the TV at the SAME TIME.

Then your screen will turn on. No idea why this works. Just stumbled on it while getting ********** that this TV, I had less than a month, suddely would not come on anymore. I was about to unplug the whole thing to take back to WalMart and just started pushing button combinations and found this worked.

Insignia 42 inch TV won't turn on

The power supply is in the protect mode. There are many things in the set that can cuase this. Most likely there is a short on one of the circuit boards, or the power supply itself has failed.

You will have to have the set serviced in order to get it going again.
