Samsung led tv UE55F7000ST
having problems diagnosing this TV
The common problem that i'm having is the relay in the power supply board clicks on and off, at same time backlight goes on and off and can briefly see the smart tv logo.
At the moment I'm thinking it is a faulty tcon board and if i disconnect it the tv will power on and stay on with sound coming through as it would normally but no smart tv logo.
The strange thing I found is if I leave it turned off for a long period
of time say overnight the TV will come on as normal, then I
start thinking maybe the tcon board is ok after all but then when
I turn it off and on again I get the clicking on and off again.
the PS board will click a bit faster with the main board disconnected
and with the two backlight cables connected or disconnected so would
that indicate something wrong with the PS Board, all capacitors look
normal with no bulges.
Any help of insight greatly appreciated.
