Hello, people, I need your experience how Mention I have this Samsung TV ln40b550 that we are running and turning on the Red Standby LED, when we turn it on either from the control or from the same TV, the Led light flashes three or four times and turns off ... if we touch it again trying to turn on the LED turns on but it does not pass there ... They guide me What could it be about?

Friend would have to check the source if you have an inflated capacitor if it is to replace and verify .. if there is no experience bring the TV to a technical service ... greetings
