SOURCE: LCD TV WONT POWER ON
A dead condition usually indicates one of the following: Open fuse (often internal, and usually pops due to other circuit defects). Short (overload condition) in the circuitry. Failure elsewhere in the circuitry. Most modern electronics have some logic circuitry, and if there is a section of the circuit not working, the logic circuit keeps the set from coming on at all.
First, if your power cord plugs into the set, check that it is properly connected. If you can get into the internals, find the fuse, check it, replace with an exact or near exact size.
If problems are beyond the simple, technical expertise will be required to nail down and fix the problem.

Replace the caps with 1000mf at 25 volt available at an electronics parts outlet.make sure you put them in correctly.the black line with a -(negative) goes back in the same way you took them out.

Hi my name is Eric,
I hope I can help you with your issue ,
If the TV is totally dead a voltage test would tell if its the power or mainboard (only two boards in the TV)
The TV not starting properly you should hear the tone noise (bleep bleep) not a ticking noise or no sound.
A long time coming on is a classic example of what I am detailing for you below. .
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 top.
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 uf and Volts values)
Samsung uses mostly 1000uf 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) .
To buy capacitors click here
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 below
best of luck to you
