Re: Samsung PN58C550 Blank Screen with sound



I know this is an older thread, but I have the exact same TV and issue as you as far as the screen flashing black and white static for a second when first turned on. Did you end up getting it fixed? The TV was perfect until I decided to do the Vs voltage increase to stop the purple glare and accidentally touched the left y-buffer board when stepping around the TV. Caused a spark and now nothing. Replaced both the y-buffer boards and y-sustain board with no luck, but as mentioned now the TV flashes static for a brief second...
