samsung LE40B620R3 lcd tv switching off and on?

My lcd tv (samsung LE40B620R3) keeps switching off and then after 4 or more clicks etc over about 5 mins it switches back on, does anyone have a similar problem?

me too just out of guarantee. I understand there may be a power supply capacitor issue. 4 on the power supply. Other posts for Samsung LE range suggest 1000uf caps 16volt X 4 if you can solder, leave off overnight and unplugged as caps can store a nasty charge. Mains plug should go into the power supply board for location, Maplins should have the caps.
