Question about Samsung LN-S4051D 40 in. LCD Television
When checking the capacitors, If they are slightly rounded on the top where the X is, the cap is defective.
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
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

Testimonial: "Information is helpful. I ended up replacing my circuit board because when I replaced the capacitors, I think I may have damaged my board due to lack of experience with soldering iron. Although now after a week of the TV working with the new circuit board, I have lost the picture. It went dark with occasional lines. Very frustrating. Would this be due to a faulty circuit board?"
It sounds like a fault in the power supply check caps on pcb they will most likley be the 2200uf or the 1000uf let me know how you go
