    Samsung TV turns itself on off fault

    Last night the kids bedroom tv started to turn itself off then back on again in a cycle about every few minutes. I looked in settings but there's nothing there then I read about a problem with capacitors wrong rated. Anyone else had this problem and done the D.I.Y fix ?. I no worries changing caps just wondered if it will cure it or not.

    The TV is a T240HD and wasn't cheap as it doubles as a PC monitor

    I had a problem on a samsung where it wouldn't always turn on straight away which was the caps.

    I have the tv open and the caps all look fine on the PSU board, no bulging. Could it possibly be the inverter transformer ?.

    It's a long shot but I have seen sammy TVs have issues with infra red. I.e block other remotes or receive commands from other remotes. Is there a new device in the same room perhaps? Just a thought.

    Samsung TV turns itself on off fault

    A little off topic but back when I was at cable there had been a load of Samsung TVs around the Huddersfield area (probably in other places too lol) that would block the signal to the cable box. If the TV was on the cable remote wouldn't work but if it was in standby the cable was fine. Really odd.

    Good thinking with the energy saving bulbs also @IANB

    @Manic, I'm gonna order one off Ebay, a new inverter transformer. If that fails there's a full power board on aliexpress for only 20 but I cant bear the thought of no tv in the kids room for 2 weeks.
