Hi all.Anyone had a problem with a samsung LE32R88 ,The tv comes on for 19 seconds then cuts out ,restarts again automatically and 19 secs later goes again.This time between coming on and off never varies even if the set is warmed up.The power board is a BN44-00155A and the main panel is a BN94-01327A ?.Any one out there can help.Thanks in advance EARLYBIRD
