Command codes Relisys plasma

[Willem]

I have a Relisys plasma 42", type RP42AB20(S)
It had very dark picture so I replaced the Z sustain board.
After that it worked again.
The problem I have now is that the remote control is not working.
I checked the hardware, followed the signal to the processor, and that is ok. This set has a serial RS232 connector.
With the terminal program Docklight I can communicate with the set.
This plasma is about the same as a philips BDS4241.
In the philips manual there is a command to switch the remote off and on.
When I try this the set does not reply with ACK.
The serial commands however are different so it seems.
Does anyone has the correct serial command code for this plasma.
