pioneer plasma receiver pdp-r05g trap switch
Hello me hearties,
3rd time i'm posting this one, so if you're bored of my ranting look the other way. Beware folks, turns out pioneer is booby trapping their products these days. You get the top cover off, you see a "case open switch" which opens once the top's off. If you now power up the set, with the switch open, your unit gets "locked". Both standby and power on l.e.d.s glow together and this state is listed in the service manual as "trap switch operation" under the LED-lighting patterns/error codes section. A little googling led me to this post..... http://www.freelists.org/archives/tv.../msg00000.html "When servicing Pioneer products such as Plasma and Projection units. Be sure the set is unplugged before removing the back cover. There is a trap switch that will open and if the unit is powered up. The set will go into copyright protection mode. Nothing will work again until a unlocking process is done. Each unit has a different process to follow to restore operation. Beware!" The service manual explains it so...... For video data transmission from the Media Receiver to the PDP-434HD and PDP-504HD-series Plasma Displays, digital signals are used. Therefore, this unit adopts the HDCP (High-bandwidth Digital Content Protection) system for copyright protection. This unit is also provided with a detection switch (TRAP switch) that will prohibit the unit from being turned on again "if the upper plate of the unit is accidentally opened," in order to prevent the panel technology from being leaked out. The TRAP switch is disabled while the unit is turned off. When performing internal diagnosis of the PDP, fix the switch to the OFF position using adhesive tape before turning on the unit. After servicing, be sure to remove the adhesive tape. Well you've probably guessed what my next question is......How do i unlock this receiver?. I'm told that it's simply a matter of keying in 3 buttons of the remote in a defined sequence. I have the service manual but it doesn't say much about unlocking. Imploringly yours, Jango |

pioneer plasma receiver pdp-r05g trap switch
JVC does this as well, and I don't understand the rationale behind it.
They are afraid someone is going to hack into this (why I have no idea), but the hacker won't be able to disable the interlock??????? If enough consumers get porked from this (one of my customers cleaned his JVC projo and lost the DVI input function), a class action lawsuit may stop this practice. Perhaps a letter sent from your lawyer to Pioneer might elicit a response from them. John BTW, why DID you open your plasma? |

I can see a future where it will be impossible to repair any electronics due to security reasons. You already can't buy certain ICs that are used for HDMI. You have to replace the entire board if the HDMI receiver IC gets zapped. I'm surprised schematics are still available because someone could use them to reverse engineer the HDMI board. I hope HD-DVD and BLU-RAY are miserable failures. That might teach Hollywood and the electronics companies a lesson. Andy Cuffe |
