That usually means a problem in the start up or deflection circuits. Diode, Horizontal ouput or driver transformer. What Chassis is this set, and I will be ableto give you some better information. Rca , GE and phillips need to be diagnosedwith the chassis number. Let me know the chassis.

Good Day, you all;
The front panel light on Hitachi TV does not really tell you much. To see what the TV is doing or better said NOT doing is remove back from the set.
If you are not a technical type person, it would be better to consult an authorized service center, but if you are perform this; 1. Remove back
2. Observe led and notice which once light, there are as many as 9 LED's.
Now that will tell you what area of the TV's circuits are to be concerned about.
Let me know, Good Luck, big IRISH.

Long story short:
Had the same problem with my Soyo.
Thought it was the power supply board problem that everyone else was reporting.
ordered one. Plugged it in. Did not work.
Inspected the Main/Logic board and found what looked like a black button that could be depressed. It is located to the right of main processor on the board. You can't really miss it.
With the TV plugged in, I pressed the suspect button. The TV made a buzzing/clicking noise for a few moments and the stuck blue illuminated power button faded away.
Curious by this, I pressed the power button and low and behold the TV comes to life!
Looks like I found a "reset" button which seems to have fixed my problem.
Thanks Soyo for not bothering to mention that such a button exists.
I hope the rest of you have the same good luck. In the event you are still in need of a power supply board, email me. I have a spare now it seems. ;)

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:
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.
