Those 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.

I would suspect a problem in either the backlight assembly, or the power supply that drives it. If it's the power supply, the part may be over $100.

Most likely the set has lost vertical sweep or the feedback from that circuit. This will shut the set down to prevent a horizontal line from burning the face of the CRT. This will have to be looked at by a technician.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

I had the same problem and finally figured out what was wrong and fixed
it. If the TV is making clicking sound, 95% the problem is the main
power supply board (PSB). The easy fix is to replace the new PSB which
can be ordered online from $80 to $100 (model # PSPF 501A01A), or you
can buy it straight from Samsung for $129.95. If you are a little handy
in electronic, knowing how to solder and troubleshoot electronic
components, you can fixed it for a little cost around $30. It was
$1.77+ shipping for my case, I guess I'm lucky.
I have read and research a lot of info on the internet forums and here
is what I learned about this clicking problem. The clicking noise you
hear when turning on the TV is the sound coming from the switching
relay. It's the power protection circuit which senses a short somewhere
in the system and trying to shut it down. The short can also be from
other boards connecting to the main PSB, or within the PSB itself. Of
course I'm not certified or TV repair man, but if it is something minor
and can be fixed by a handyman, I'll try it first. If it is beyond the
basic, a major problem or you have no idea about electronic at all, have
it serviced at a certified TV repair shop.
For my case, here are the steps I took to troubleshoot it:
1. Unplug all 4 connectors on the main PSB. Use a Voltmeter to check
the voltage on pin 10 of
CN804-1 (read the print on the board where it said SB 5V), this is the
standby 5V supply. If the voltage is low, not present, or spike on and
off, the issue is the power supply.
If the TV is totally dead after the clicking stage, this stand by
voltage should be 0V or spiking up and down. For my case, the Power
thermistor is dead.
2. Visual Inspection: Visually inspect the PSB for any damaged
component, especially all the ESR capacitors. Look in the back of the
PSB to see if all the solder traces are ok, no crack or black
stain causing from burned components. If you find any damaged
component, replace it.
3. If everything look good on the main PSB, then the problem is likely
on somewhere else, may be the Y-board. At this stage, you should
consult with a certified TV repair person.
Here is what happened to me:
Symptom:
-First stage: When turn on the TV, it was clicking for less than one minute then back to normal.
-Second stage: After 3 days, the clicking last longer to about 4 minutes then back to normal.
-Third stage: After 1 week, the power button's blue light is flashing
when the TV is off. But "might" turn on after clicking for about 8-10
minutes.
-Fourth stage: No flashing blue light, no response. The TV is totally DEAD!
Solution:
-Visually inspected the PSB. Everything look good except I found an NTC
Power Thermistor (next to the switching relay) was bad. It was burned
and opened. The number on it is SCK 206.
-I checked the stand by voltage at pin 10 of
CN804-1. I have no voltage there but a spiked voltage up and down on
the meter (no reading). Definitely the problem is the PSB.
-All solder traces and capacitors look good, so I decided to replace the
burned power thermistor. The big problem is to find a new part online
because there is no match for SCK 206, SCK 206 is not the part number
and no one on the online store knows what substitute part for SCK 206.
After a few days searching for the part number, I was lucky to talked to
a technical support from a Amethem company which designed the NTC power
thermistor and he quickly recognized the Samsung SCK 206. He gave me a
substitute part number of a much better quality power thermistor. The
part number is SL227R010 (7Ohms, 10A).
When you have the correct part number, you can find it everywhere. The cost was $1.77 each, and I got it from Digikey.com

I solder the new component back to the main PSB. My TV came back to life. Hope it help for your case.

Same problem, power light goes on but no picture or sound.
same, light flashed, but the picture does not come on
Same thing here...bought this for my mom and suddenly it just stopped turning on. In fact she walked away for a few minutes, came back and it was no long on and would not respond to the remote though the red light is on. Worst part is, just to prevent any potential power supply issues, I also bought her a sinewave output UPS as we can have flaky power here. So, I did everything possible to guard against any power issues...and the power supply (guessing but that seems the most reasonable point of failure, craps out just short of the end of the 1yr warranty. Worse yet the thing was around $800 last year when I bought it for her...once was a time an $800 TV would last 30-40 YEARS...so tired of this freaking treadmill!
Now I have a about 2-weeks to get it fixed before the warranty expires. Even worse I have to deal with support, which is likely located in some "We Hate All Americans" ditchwater 3rd world country.
She is in a convalescent care facility, legally blind after 17 eye surgeries and a bigger screen is the ONLY way she could have a bit of enjoyment watching her Lakers. Pretty disappointed in Samsung right now.
