Samsung no backlights.

I checked all the capacitor caps and none look remotely bulged. Even took a magnifying glass to get a better view of the bottoms of them (had one blow the bottom out on a computer monitor) Everything looks good. Turned the set on last night to check and the backlights are working once again. Left it on for 7 hours, turned it off overnight, working fine all day today. Sometimes the backlight will stay out for hours. Sometimes it only a few minutes. Just frustrating that the problem comes and goes.
