Samsung UE37D5520 keeps turning off and back on again


Well-known Member
My Samsung UE37D5520 has just started turning off and back on again. I've unplugged everything except for the power cord and aerial cable, but it still keeps power cycling.

Any idea what might be wrong?

I must have bought it about 6-7 years ago, and it was our main TV until last year when we replaced it with an OLED. It then went into the garden room, and worked fine for about 3 months before this started.
