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

SOURCE: Samsung LCD 40 Sensor & picture problem.

Since this is affecting several functions, the problem is likely the main power supply. It may be that the supply itself is failing (switched mode power supplies like hari-kari) or an assembly (possibly the backlight invertor) is producing a fault condition which is causing the supply to drop out to protect itself.
Try the instructions below -
The supply is normally built on a separate board since these are often out-sourced by set manufacturers.

Unplug your set overnight to allow potentially hazardous voltages to discharge, remove the back panel of the set so you can see the guts.
Look for a smaller board with larger parts on it; some cylindrical (capacitors), others block-like and relatively large (chokes and transformers).
You should also see a relationship between the board and the incoming AC.
Check the board for a label or if not present, a stamped-on number.
Call the manufacturer's service center with your TV model number and the number found on that board and inquire about repair/replacement costs; if both are offered, they won't be that much different.
If you must buy a new board, don't dispose of the failed one as there are smaller companies that can repair it for less than the mfr. and then keep it as a spare as this problem will likely arise again.

TV KEEPS TURNING OFF AND WONT STAY ON


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

The power supply needs repaired NOW. I suggest you do not play it---unplug it ---and take it in for service. If you continue to play it you will price yourself into a new tv.
