Question about Samsung LN-S4051D 40 in. LCD Television
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?
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.
