Default upgrade.

JVC LT-32DE9

If after switch on the loader system starts then goes to picture before disappearing then going back to the loader again. This means the LCD is not watchable but just on a re cycle motion.

Cure
Go to menu and installtion select default and then remove the aerial, let it go through tuning with no channels tuned. Refit the aerial then reselect default to complete tuning which will then give a normal operation of the LCD set.
