50" Samsung S50HW-YB02 has sound but black screen

[XChris1632X]

My Samsung is 8 years old and has had a hard life. My wife did day care and would run 16 hours a day Mon-Friday. We have surely got our money out of this tv and I'm not shocked it failed but I am not ready to lose it. I enjoy the picture on this better than my brand new 60' LG.


I paused the tv to help make my wife make the bed and came back to a black screen. Pressed play and had sound but no picture.

I opened up the back to find 2 blown capacitors.
C5709 v9A 25V 680uf
Cx403 10V 2200uf

From what I have read it sounds like simply replacing these caps will bring it back to life.
Is replacing these caps going to fix my problems? Also, I tried ordering replacements but got lost in the options. Any suggestions?

Thanks for reading.

I do want to mention that I am really ignorant in this department. I do cars not electronics normally but I would like to try.

Were these blown caps on the power supply board or where were they ? Take some pics with the back off and point out the location of the bad capacitors.

C5709 v9A 25V 680uf, will be on the ymain


Cx403 10V 2200uf, will be PSU

Sound with no picture I suspect will be predominately due to the common upper buffer board failure and blown ymain board.
