Hello everyone.
I am pretty new in TVs and Receivers but I am a computer engineer.
I recently got the non working Pioneer 50" plasma PDP-506PU with the receiver PDP-R06U.
I connected them together and hoocked the HDMI port. The TV wasn't show anything. The receiver was reacting on remote. It was switching between standby and On.
I opened the back panel and got very dusty boards inside. I did vacuum cleaning and, just to make sure it is working before I put everything back, turned it on.
Of course the Trap Switch fired and now my receiver has all LED powered:...

Re: Pioneer PDP-436SXE schematic/service info needed



Hi. I have the same problem. The Trap switch. Cannot reset it back . Reading the service manual [URL="file:///H:/Docs/pioneer_pdp-r06u_pro-r06u.pdf"]here[/URL] which says I need to send to RS-232 the command
TSN Disable the TRAP switch
TSY Enable the TRAP switch
The com port should be at 38400bps. But by default the RS-232 is not working. SR+ is switching instead. I connected to the port via PUTTY set the speed but cannot send the command. What did you do to reset the switch or...
