SAMSUNG BN44-00264C power board	Can't Post

Hi folks I have a samsung tv that randomly switches off, I'm assuming the issue is the with the BN44-00264C power board.The capacitors look okay although I appreciate that's not an accurate assessment. Could anybody point me in the right direction please, is it likely to be the capacitors or is it some other component? any help would be appreciated.

yeah strange that,I tried the link that you get but I cannot click on anything it just zooms in and out, I'm guessing from the title though it's a service manual? I did watch a good youtube video earlier that shows how to repair a dead power board like I have, which involved replacing a few soic's,a ceramic type capacitor, resistor and the 5 components which are screwed to the heat sinks which I;m guessing are regulators, I'm quite capable of changing those but I'm sure it's an overkill in my situation as mine still has power most of the time.

Most inverter circuits monitor for abnormalities and will shut down CCFLs (and usually the whole set). Bad CCFL bulb(s) (or its contact(s)), bad solder joints are a couple of likely candidates.
