Hello,
I have a Samsung Tv Model LN40B540P8FXZA. Problem: It will turn on just find and after a few second it will start to flicker and then go to black screen i will turn on and off a few time and then completely off, Sound remains. If I turn it off and then back on it will repeat same process. Any suggestion on witch part might it be?
Is this a good question?

David Torres, Before replacing parts try a resetting.
– Unplug TV overnight. Plug back in and try, may correct issue.
– Unplugging the TV and everything hooked to it, then plugging one at a time back in may clear the problem and point to the device causing issue.
– Be sure the TV is set to the correct input. If it is set to DVI or Component input when it should be in the HDMI input this will cause issues.
Still no go, unplug TV,remove the back and check for loose wire connections, remove and reseat the connections and try TV, Look for bulged/burnt/leaking capacitors on the boards or hot spots to signify burnt/damaged components, replace capacitors, etc, if able. Check the link's below for more trouble shooting suggestions and fixes. Good luck.
