Need more info on the unit.
Model, Serial # and Version # on side of unit. It sounds like you either have powersupply problems or cold solder joints in the power supply. Resoldering board may solve your problems.
Let me know, Have a good day. Jay

SOURCE: 2 year warranty
the Majority of problems on this and all other LCD TV's are capacitor problems the power pack needs smooth power to work correctly however the warranty should be valid and you need the proof that you bought it and you need to know who to contact about the 2 year warranty it may be Emerson you need to speak with not Walmart. I would contact them next(Emerson), or whom ever the third party repair service is that will cover the Warranty.
hope this helps

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 .
Great that its under warranty
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

Testimonial: "I talked with the technician who will be coming with the new power suppy this week to repair it in home. Good job & thanks!"
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.

Check for bad capacitors in the power supply. The capacitors will be bulged on top. Typically there will be 3 or 4 caps with this problem. Thanks for using fixya.
