This problem started about a week and a half ago. Watching tv then it just went off on its own and the power light in the center of the tv went of as well as if there was no power then it just lit up again and switched itself back on. It did this about 9 times then it seemed to go ok again. Then it started again then ok but now if you turn it off at the standby button or remote and go to bed etc ten minuets later it turns itself back on so now you have to turn it off at the switch at the back or unplug it. It is now even worse over the past two days as soon as you power it up from the swith its ok for a couple of minuts then it turns of i counted how long it takes to switch back on and every 8-9 seconds it starts up for about 30 secs then off for 8 - 9 seconds this is now just ongoing no matter what i do hope this helps thanks.
Yes im in the uk
Can this be done by myself and what would i be looking for ie where would the board be next to the standby button ?.
