CHILD LOCK Help needed

Hello i recently had a problem that my tv just locked itself which i think is the same type of problem, i contacted Daewoo and they gave me the following code to try and it worked, not sure if it will do the same for your set, but it might be worth a try.

press the following buttons in the remote in sequence

BLUE
YELLOW
GREEN
RED

STANDBY TO TURN OFF

STANDBY TO TURN BACK ON.

Hope this might help, if not try contacting Daewoo Electronics website and put in your model number.

Regards

H wilson
