turn your tv on

Press and hold 'SET' button

while 'SET' is still pressed press 'TV' button

indicator light should be on steady

now press 'SET' again

point control at tv and hit 'POWER' button

keep pressing 'POWER' button and a different code will be sent each time.

it may take a lot of presses to find the right code!
