These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Spot remover. Black marker? Maybe not. (;^D).
Really, if it's just a little white dot on the screen, it may just be a bad pixel. Those things happen. The manufacturers warranty against more than 'so many' bad pixels, but if there's just one, I doubt they would replace it. If it's a big block of white, you might be able to get it replaced.

The green blinking light of death this is called, it is the digital portion of the set trying to boot up, only one simple thing to try here, get at the front keyboard where the Tiny reset button is and unplug that board, I can tell you how if needed.

The light should if power was removed and returned blink for about 70 seconds and go out--then set can be turned on.

The common circuit problem that (other than a bad reset button) is 4 filter caps on the main power board that puff up---follow power cord to that board and look for:

The reset button is easier to look at and disconnect, the caps are usually easy to see if puffed up--if I remember this model there are 4 1000uf(microfarad) at 16 volt rated caps that go bad, if even one is puffed replace all four--kits do exist or you can buy the caps by themselves. The kits are not real expensive and may come with the pico fuse that is in that power supply.

If the model above is correct you are describing a bad optical light engine, about the most expensive part inside that set.

Check and replace damaged component/s in the audio output circuit. Just check the speaker first, and proceed. Visit the site named 'Electro-help' for more details. Click this link. View it in "Timeslide" or "Flipcard" option, which can be selected from the drop down box menu by the [Sidebar] tag, at the top left corner of the display window. You can also click the [Home] tab to see the latest updates. It will make search easy. There are more than 1350 posts to different brand TVs now.

if you can check the power supply board look for a bulging capacitor which cause of voltage drop not to turn on the relay.

Have the internal voltage regulator checked. Possible that it's failing.
