LN46B550K1F picture keeps coming up then crashing

Post by bubbasweet »

Hello My Samsung LN46B550K1F Powers up plays music and then see image then gone. TV is still on and then does over and over. If i unplug HDMI it stays up saying no signal but as soon as I plug in HDMI same thing. Picture for a second or up to a minute then crashes and over and over. Power Supply board or main board? What do I check for on power board to see if it is power board or main board. Thank you. Are their any common things to check that usually fixes this problem? THX
