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/

SOURCE: my emerson tv standby light is on the power light flashes twice

Mine stayed in stanby mode and all I had to do was to switch the plug to a different outlet. The power strip it was on wasn't providing enough power. It worked fine for a month before I had a problem.

Emerson tv lc320em1f won't turn on and power and standby lights are on at same time not blinking. Stays on even if not plugged in until a loud whine. Was thinking capacitors but not sure.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Ilo LCT32HA32 tv wont turn on, no red standby light

It could be the power or main board that is giving issues...if your able pull the back off and look for a pin on connector marked PSON or PON...that is line that tells the power board to come out of sleeping and go to work, you should see a change in the voltage when the on button is pushed, if you do then the main is doing its work and its the main if you don't see a voltage change then chances are its the power board
