Question about Televison & Video
Samsung 46'' LNT4661F 20 months old. Last few days when tunring on it makes several clicking sounds & today it took 45 seconds for the picture to appear. The TV is under warranty till Jan 30 2012. What's the problem, is it the power supply?
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 wrote up a tutorial on how to replace the capacitors if anyone else has this same issue (I just had it happen to me within the past few weeks). I have included photos for each step along with instructions.
