Question about Samsung LN-S4051D 40 in. LCD Television

1 Answer

Samsung model LNS4051DX/XAA won't turn on, just clicks

My LCD turned itself off for mo apparent reason and will not turn back on; all it does is make a click sound and the power light blinks four times then repeats the cycle again. I have spoke to a tv technician and he thought the problem was the signal board. Would you agree? Several other people have had the same problem that I can tell, is the solution the same for everyone?

    I have exactly the same problem apart from for a few days it would come on after a while if you were patient enough to wait. Now I just get the clicking and light flashing which is not very entertaining.

    And yes I just started having the same problem last week. Let me know if you find the solution.

    Around two weeks ago the TV began to have a delay in starting of two minutes. After around a week, the TV began taking around four minutes to boot up, and sometimes without sound. The only way to make the sound start would be to restart the TV and wait for it to come up again. Now the TV is loosing sound after 5 minutes and the screen is degrading in quality. The TV is now taking a very long period to even start, if we can get it to start. PLEASE HELP!

    I have the same problem started happening last week. Its almost 2 years to the day that that I bought the TV. Its very fishy! The TV clicks several times, but wont turn on.

    I am beyond UPSET, seeing as how I just finish paying the t.v. off last week.

    same problem...samsung said to unplug for 30 seconds and try again. This works the first time and then the next time I turn it on i have the same problem. It's not even 2 yrs old and I have a few more payments. With a 1 yr warranty, i'm screwed...This is the last samsung product I'll ever purchase

    My 25 month old TV became more and more difficult to turn on recently. It finally wouldn't come on at all today. It would just click and the red light would flicker on and off. I took off the back and found 4 swollen capacitors in the power supply. Got 4 new capacitors at an electronics supply store for less than 2 dollars. It took my son less than an hour to replace the capacitors. It powered right up and is running fine. Cap. Specs: 1000mF 10V 105degrees

THE PROBLEM IS Faulty parts on PS board , bad press for Samsung

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.

    Did that, replaced ALL capacitors in hopes of not seeing a blown one. This still happens. I even used a jumper in suspicion of a scratch on the board from soldering. Still clicks.
