    Jaime,
     
     Thank you very much for all the information you gave me. You saved me a fortune. I opened the back of the tv and found the power supply board. Found 4 capacitors blown, replaced them with radio shack capacitors and the tv works great. It cost me under $7. Thanks again for all your help.

    We were watching a movie, all of a sudden a low intensity sound of blast came from the tv and it shut down immediately.I took out the plug and switched on the tv after some time but it didn't turn on. There was a continuous clicking sound but tv wasn't turning on. Showed it to a technician, he says stand by power supply is the cause and the power supply board needs to be replaced

I have a samsung tv model #LN-S4051D. Problems: Turn on the Power button (red light blinks at power button with clicking noises every 30 sec. or so) without pictures. Please help. Thanks


This is a comon problem with the Samsung LCD HDTV on the Power Board.

You can repair or replace faulty parts on PS board.

When checking the capacitors, If they are slightly rounded on the top where the X is, the cap is defective. See the Youtube below.

Because the Samsung LNS4051D would not turn on and the power
LED would blink 4 times and the relay would click and this
would repeat again and again. I replaced power supply board
parts CM806, 811, 812 & 817, all 1000 uf 10v capacitors,
three had their tops bulged up slightly that I missed on
initial visual inspection. After seeing the reports of
problems with these caps on
http://www.fixya.com/support/t1336881-will_not_turn_or_off ,
I replaced them with Radio Shack part 272-1032, 1000 uf, 35v.
They are slightly bigger, but fit OK. TV is working fine now.
Cost was 4 x $1.59 = $6.36 plus the time. I saved between
$100 to 300 in the process of either replacing the board or
getting the unit serviced. If you are not comfortable
replacing components which means using a soldering iron, you
can replace the power circuit board, available from
www.Samsung.PartStore.com.

Samsunb 4051: TV screen turns off sound stays on.


Most likely this set has an "integrated" inverter, as most samsungs do--and this DOES sound like an inverter problem. Make SURE thought, there are no more bad "10 volt" caps on the power supply...ALL of them need to be replaced no matter HOW they look.

Sound yes, but no picture on tv


If you have sound on the stations this is a problem in the display. Take bright flashlight and hold it against the screen. Look for an image around the edge of the flashlight. If you see an image then it's one of three problems;
1) The inverter board is bad.
2) The CCFT (cold cathode fluoresent light) are bad.
3) The power supply to the inverter board is bad.
Someone knowledgeable in electronics can replace the bad part(s).

Samsung LN-S4051D Tv Cliking noise only but tv does not come on.


I had the same problem. I work for a mother board manufacturer w/offices in New Jersey and brought mine into our engineering lab after Samsung told me tough luck. Anyway, one of my engineers fixed it in 10 minutes. Essentially, he replaced the 1000uF capacitors on the power supply board with 2 cent capacitors instead of the 1 cent capacitors that had blown out on the CHEAP SAMSUNG POWER SUPPLY BOARD. You can tell the caps are blown via visual inspection. The top of the cap should be perfectly flat and a blown cap will be convex on top. Unfortunately, there are also 2500 uF caps by the same cheap manufacturer on the board as well and we don't stock that value for our products. According to my engineer, those will most likely blow next since he replaced the others with better caps, but I'm getting samples of those and will replace them shortly. After that this piece of **** should last me at least another 2 yrs! It's been working for about a week now w/no problems. Hope this helps.
