Having seen this issue a few other times, please allow me to confirm that there is a problem with your remote. You mentioned that you have attempted to erase any macros. My suspicion is that when following the macro erase instructions on page 39 you are pressing the M1, M2, M3 or M4 button on step 2. However, the macro command that you may have inadvertently programmed is not on one of these designated macro buttons, but rather the Power Off button.
To erase the macro command on the "Power Off" button, please use the following procedure:
1) Press AUD and MUT buttons simultaneously.
The red LED and the AUD button remain lit.
2) Press the POWER button.
3) Press the CHANNEL UP button to store the command.
The stored sequence is now erased from the power button.
If you follow this procedure, you will be able to use the power off command for the Model 950 again. I apologize for any confusion this may have caused. Please do not hesitate to let me know if you have any other questions.
