The TV model number is ***** I have turned off the power to the sky box and will wait for five minutes before turning it on again. I did turn off power to box at the mains before, but did not leave off for more than 20 seconds!
I have turned the tv and sky box back on and while the box was initialising, the tv was a blank screen, except for the display in the left top corner, scrolling through all the channel numbers continuously. The remote would not do anything. Now that the sky box is back on again it is exactly as before - full volume, and the disconnecting anynet+ device message
The buttons appear to be fine. They do not seem to stick, and I have cleaned them with contact cleaner.
I assume that swapping the main board in the TV is an expert job and I will need to send the TV for repair. Is this correct? Is it a big job?
