All the codes test OK

G,H & I go left it only goes left once.
L & M go left it only go left 2 or 3 times.

All the codes make the LED stay on.
The number buttons work even though the LED in the Receiver stays on.
But if you use foe example the TV GUIDE button nothing happens apart from the Receiver LED coming on, press a number button that will return it back to the viewing channel.
It seems all the function buttons (HELP, INFO, POWER, EXIT etc.) don't work.
But the number button do.
