Default Bn41-00813 issues

Hi folks
I've come across this fault several times before but never found a resolve, I know it's been spoke of on here before just wondered if a solution has been found.
The fault is that the set will cycle , it will come on and work fine for 15seconds or so then power off and straight back on for another 15 secs and so on.
I've replaced EEPROMs which hadn't cured it.

Post the part number of the board BN94-
also if you could post a picture of the board that would also help us.
Try re-flowing the main IC

Did you already try heating the board with hair dryer, especially under that big metal shield?
