SOURCE: my flat screen tv does not have a picture or

I've had the same problem with a 32" model LC320EM82S. All the Emerson TV ( no matter what size ) are having the same issue.
I'm sure with your TV, the green light is blinking before the TV automatically turns OFF. Basically, the TV is trying to power up the screen and has failed. Protection mode turns the TV OFF to prevent other parts from being damaged inside.
My solution for fixing my TV was replacing one bad inverter transformer of six on the Backlight Inverter/Power Board. Here is what my board looks like: 767c946.jpg
You can see the six inverter transformer on the bottom of the board. It's what supplies power to the screen. Your board may look similar. You can sometimes find a whole replacement board over the internet for a good price. Shopjimmy.com is a good place to start. Just start searching by your TV model number.
If you have some electronic experience, you can repair the board itself by finding a Service Manual over the internet for less than $20. It will have all the part numbers, schematics, and diagrams you need. I would investigate the inverter transformer for your problem.
I hope I helped you out with your problem.

SOURCE: Television Not Powering Up Intermittently

Hi Check the standby power supplies, then the run supplies, then the h-driver circuit, then the H.O.T and flyback circuit. And in general look for bad transistors, diodes, capacitors, resistors, faulty solder connections and etc. BE ADVICE!!! if you don't have any repair experience and electronics knowledge leave it. Take it to an experienced tech or a service shop. Good luck

Hi, If all else fails, try do a hard reset. You can verify from your manual, but in some units, this is merely unplugging the unit from mains for a couple of hours. Try again, if it still shows error codes (blinking lights) you probably have to seek the services of a qualified professional. Hope this be of some help/idea. Good luck and kind regards.

SOURCE: power led blinks but no picture or sound

Had the same problem myself. Took some doing but I managed to find a service bulletin that I downloaded. The problem is with the siene module and all you need to do is unplug connector JP63A from the main board and your TV will work again.
Take the back off the TV (there are a lot of screws) and look on the left hand side of the main circuit board that is mounted in the center of the TV. You will see a small white connector that is labelled JP63A, simply unplug it. Plug the TV back in and let it reboot. That's it, should be able to watch immediately.

Green power light comes on for a split second, then red.


The power supply (AC adapter) is bad. It has enough power to light the red LED, but not enough to power the TV.http://shop.ebay.com/?_from=R40&_trksid=m38&_nkw=12+volt+5+amp+power+supply&_sacat=See-All-Categories

LCT 2662 after caps replaced I loose backlight.


make sure the caps you installed are the exact replacements. Changing voltage capacity or timing will cause the circuit to fail.

No Picture & No sound. Red LED, Green LED, Red LED.


If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.
