The tv won't power on.
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.

Blinking codes details of many popular brand TVs are given. Surf the site with patience.
If blinks continue without any pause, the main board is faulty.

Your LCD has gone bad or their is a high voltage problem that powers the LCD. Usually a inverter board.
SOURCE: power light keeps blinking and power will not turn
Check back light inverter,if ok then check the 12V and 5V line,if not OK probably the IC in the power supply is defect ( F9222 )

Hi my name is Eric,
I hope I can help you with your issue ,
The TV not starting properly you should hear the tone noise (bleep bleep) not a ticking noise or no sound .
These Samsung LCDs have problems with the power supply capacitors going bad, a servicer will charge between $200 and $450 to repair it replacing either the capacitors or the whole board.
here is a DIY (do it yourself) solution:
It could be just a few bad capacitors on the power supply, if you want to attempt the repair yourself you can do a visual of the power board caps will appear swollen on to.
We do not recommend do it yourself, but depending on your knowledge and technical ability you may be able to.
with the back removed you will usually see two circuit boards the upper one is the power supply, it has a few capacitors on it (cylindrical standing straight up soldered in mark on the sides with the positive/negative sides and MF and Volts values)
Samsung uses mostly 1000Mfd at 16Volts rating capacitors, they cost about $1 each (680mfd will also work fine)
usually I replace about four of them (or all the bulged on top ones) .
The power board and back unscrew with a medium philips screwdriver, if you do not know how to desolder and resolder then do not attempt this as you may damage the TV more than fix it.
Im am posting a photo of some swollen caps on a board so you know what they look like;
best of luck to you
Hope this helps, if it has solved your issue please click accept
But if you have more questions please respond and I will reply asap
Thanks
Eric

I just fixed this very same problem. It is the capacitors are the problem. However, I think that if you have some minimal skills with soldering, you can fix this yourself. You just need to take out the system board, then the power supply parts are on the top right. The bad capacitor(s) will be bulging at the top and possibly have some brown stuff coming out. The ones that go bad are 1000microfarad, 10V, however you can replace them with higher voltage. I got 35V caps from radio shack for 1.59 each. You just need to solder out the bad ones and then put the new ones in and solder. Remember that the negative end goes on the side with the bold black part of the circle on the system board. Then just cut off the extra ends of the capacitors. If you are capable of doing this yourself, you will spend at most 6 dollars instead of however much a technician costs.

power suppy needs replacing...according to samsung and other forums i read when mine did this its a common problem
Main Board / DC Alert
Error / Audio Error in this case main board defective please replace the main board
