Fix PS Board parts.

Faulty parts on PS board , bad press for Samsung.

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

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.

Hello,

Before you start doing the repair yourself you need to know that the LN-S4051D is covered under a class action lawsuit settlement. If you are having power issues with this unit you need to contact Samsung and have the unit repaired free of charge under the terms of the settlement. You can get more information about this here:

Samsung LN-S4051D slow to turn on.


You are likely to have a module bad....part number BN94-00864A and if you take it out (unpluggs) you should inspect it for capacitors that may be domed or pooched up at the top. If so they should be replaced first before getting the module as the capacitors are about $1.00 each. Do a search for Samsung parts online if you need the module and call them toll free

I have a Samsung LN-S4051D. Power on delay?


Is probably that the power supply is having issues with a component, it might be something very simple, since tv still turns ON, is probably that is just one capacitor or another component. If you can have someone to electronic sabby to check the oiwer supply they might be able to determine where is the issue, if not just take it to a shop, it shloudnt be expensive

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.
