specifically bn44-00267b in a sammy ln52b530p7fxza
history:
two years ago the tv would not turn on. when you turned on the power, the red stdby indicator light would go from solid to flashing a couple of times and then back to solid.
i pulled the power supply board and replaced the following caps:
cp814
cp8?? (next to dm801)
cm807
cm808
cm811
cm818
cm819
cm820
(i think that was it)
problem was fixed..
present time:
issue has returned, but at this time its intermittent. sometimes the tv will power on and sometimes it will not. when it does power on, after a while the picture will go black (off automatically) and the stdby indicator light will come on, and then after some time the tv will automatically come back on.

would like to get to the root of the issue this time around. got scopes, meters and other test equipment at my disposal, but need some insight on what to test.
