Hi.......Ive got a KD43X8309C which has lost the HOME SCREEN at START UP and thus access to features. This occured after the last update!!!

Cant seem to restore. Cant even access shipping condition/factory settings which may help to restore?

Can anybody please help? Even instructions on how to access restoration of factory settings without access to home screen would be helpful........Have tried holding the standby button and UP button for several seconds as described but this doesnt seem to help

Many thanks

Regards

Mick
