Mend Samsung LE40M86bdx Mins Going Changed

Samsung LE40M86bdx?

My TV has started tuning itself off and on after 15-30 mins then keeps going off and on.
Tried : Changed capacitors on power board (looked OK anyway)
Reset from service menu, Changed HDMI socket
All of the above appeared to work only for fault to reappear

Sorry yes turning.
Changed from hdmi1 to hdmi2 cured problem ?? then next day fault reappeared.
same thing happened on resetting firmware worked for 2 hours then fault again. Nothing obvious on power board I am beginning to suspect the main board

Quote "tuning" Do you mean turning.

Changed HDMI socket. WHY?

Going on assumptions Power board faulty, Capacitors Are not always to blame
