No. i think you have a power problem the switching power supply of your tv is damaged. But you can try to reset it if you know how.

The power supply regulator board to your TV is now working fine, and has no problems at all, as, there is standby light. Check all the other voltages comes out from the power board, to main board. If all of it found OK, the fault should be at its main board.
About blinking of standby/power light;
These blinks (flashes) are fault indication. By the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit stage inside the TV. Count the blinks occur at one time switch ON, carefully. Do it once again, and make sure about the number of blinks. If the flashes are continious, non-stop, the main system control IC should be suspected. If you wish to get more details, check the site linked here. It has blinking codes detail to many brand TVs. Pull up older posts. Check the site in 'Mosaic' view. It will make search easy. http://electronicshelponline.blogspot.com/

It sounds that the main digital board has damaged. 12 blinks indicates it. if you wish to know more check this link for more details about 12 blinks to Emerson TVs

Please ignore the first solution as that blink code definition is for a Sony CRT based set, NOT an Emerson.

Carefully examine the LCD panel itself with a flashlight and look for small cracks. Based upon your description of events, I think that the panel is actually cracked. This usually only prevents a picture from showing. The red lights are an indication of an internal problem and the set is in shutdown to prevent further damage.

Without seeing the actual unit, I cannot make a definite diagnosis, but I would initially suspect a power supply problem that may be relatively cheap to fix. If the set is relatively new, I'd invest in a detailed repair estimate. Post the info here from that estimate and we may be able to walk you through the actual repair.
