Hi John,
I hope you have tried unplug TV from power socket but it didn't help.
Does menu screen come up if press menu button on TV or its remote control?
Thanks.
Customer: replied 2 years ago.

Press menu button and channel 8 comes up. Press several times menu appears but cannot change anything. If you try menu disappears.

Expert:  Shahid replied 2 years ago.
Thanks for the info, have you tried to press menu button on TV itself?
Customer: replied 2 years ago.

Tried the function button. Just got a all DVB channels. banner across the bottom of the screen saying CHANNEL 8. If I press the up or down buttons on the TV I can change stations but it reverts to channel 8 in less than 10 seconds. I f I press the button twice I get channel 6 and it reverts to channel 88.

Turned it off again. Turned on channel 1 comes on for about 5 seconds then switches to invalid channel 8.

Initially I was just watching a programme and the TV switched to channel 8

Customer: replied 2 years ago.

Whatever button, I press 8 comes. The more times I press, the more eights I get.

John,
If we could get menu on TV then need to go to Setup > System Menu and select Shipping Condition to reset the TV to default settings (like just out of box) which might help to resolve the problem.
And if TV doesn't allow to navigate in menu for reset then I'm afraid it is main processor chip internal failure and main board of TV will need to be replaced to resolve the problem. Required main board would be available at following supplier links for 36 to 60 Pounds..
