Question about Samsung LN-S4041D 40 in. LCD HDTV
Replace the 4 Capacitors on the power supply board that are buldged up they are on the top right corner of the board where the ribbon jumps from the power board to the main board with ones from Jameco Part Number 606521 they worke perfect but make sure you put them in with the correct polarity easy to do just keep an eye on it. Very simple repair and took me about 30 min to take itapart solder on the new ones and put it back together all for under $10.

My SAMSUNG LN-S4041DX/XAA
.ExternalClass .ecxhmmessage P
TV just clicks on/off repeatedly but it won't power
up. The LED flashes 4 times and then it goes off. TV is 3 1/2 years
old and of course out of warranty.
I am not ready to call a service person because they never seem to do anything but replace boards which is what I am doing.
Here is what I have done so far:
1. Replaced 10V capacitors on power supply board with higher voltage ones but same 1000uF rating. Didn't fix the problem.
2. Replaced entire power supply board with another one. Didn't work.
3. Now I plan to replace the main board on the right and the T con board at the top. I will do this separately to see if it fixes the problem. I will return whatever board that I don't need.
Can anyone think of something I am missing? Is it an easy fix that a repairman could do if he's good? I'm ready to call SEARS after this.
