Such a let down

Stylish black frameless screen, very well featured LCD HDTV with great colour, picture and sound qualities. Proud to own it.
Until oh dear begins to fail on start-up. Powers on then switches off, cycles back and forth, cycles about 6 to 8 times until it settles down and then carries on without problem. Until the next power on.
Not a remote issue, tried directly on set without remote.
Called Samsung. Apparently they have a capacitor issue with some LCD models where they will accept repair. Not this model.
Engineer unable to fix on Site back to workshop, not a capacitor issue most likely the powersupply card or the screen. Megabucks. AVOID.
