1I have a Samsung pn50a550s1fxza. That has the power board bn44-00222a
My Tv takes about 15-30 minutes to turn on in the morning now. It will cycle on and off on its own when attempting to start sometimes when it tries to start and if the screen does come up the first couple times it has thin snowy multicolored lines throughout the screen followed by a loud high pitched squeal out of the speakers and eventually automatically shuts off.. When it does start it will stay on until I shut it off. I can leave it all day and it wont shut off. I have read that caps may be an issue. I took a look and all of mine look fine. none are bulging or leaking anyway...
