Re: samsung LNS4695DX TV Has blinking power light - No Picture

I replaced all electrolytic capacitors on the power supply board, and it fired right up. Been working great for about a week now. The original CapXon brand caps are total crap. Some of the worst caps ever made. C'mon Samsung. I used all Panasonic capacitors as replacements. And wherever it calls for 10volt, I used 16volt. I read that Samsung was sued for using 10 volt caps in the 12 volt circuit. Oh, I noticed the TV picture is starting to look better and better over the last few days. Maybe the new caps are forming up, or I'm adjusting to a different TV, Oh, Well, Who Knows. I'm happy !!!!!!! Glad I did'nt give up on it.....

Hope this helps others.

I am now working on this model as well, has any found where the typical soldering cracks are located. I have already replaced all of the larger caps, except for the 50v 10uf caps.
I may just spend one night hitting every joint with the iron.


Happy Holidays everyone !

What does heating the board do ?
I have yet to replace the 50v, 10uf caps yet (in the mail today) but I have heated the heatsink at UB801. I just took my iron and placed on the metal for about 3 min and that allowed the TV to actually turn on. Just wondering what that mean exactly.
I then turned it over and hit those joints with some new solder thinking that there may be cracking there, but it didn't resolve.
