Pioneer Plasma Receiver PDP-R05G trap switch

[jango2]

Hello fellow techies
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.....

"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?????????
Thanx in advance,
Jango

Sorry I don't have the info you need, but this is similar to what JVC
does. They use a photocell to kill the DVI board if light hits it (as
in the backboard removed). The TV continues to work, but not in HD.
What I don't understand (besides the obvious) is how these booby traps
protect the manufacturer. If anyone has the skills to hack these,
they might be able to develop the skills necesssary to bypass the
Pioneer's switch, or put black tape over the JVC's photocell.

The next generation of Blu Ray players will be equipped with powerful
explosives that will kill everybody in sight if the unit detects possible
tampering or if someone puts a DVD+R in it.

Okay, it's time for the inevitable career shift then. Exploding metal
hallide projector bulbs were bad enough, but explosives i can't handle.
So where does an electronics technician who's been in this field for 22
years go ?.
Jango!

 

Plz can you help me for this issue i also facing this problem in my product (PDP-R05G) PIONEER MEDIA RECEIVER . THANKS FOR YOUR TIME PLZ .

There's a youtube video that supposedly explains the procedure, although I don't plan to watch it so I can't say for sure if the procedure works. Of course, none of this will repair the problem that caused you to open it....

 

I'm going to say - IIRC you need the original remote to do it. At least that's what I remmber.

Good thing e learned about this and now just use a p[iece of tape to hold the switch.

Certain years of JVCs had an DVI input module tht apparently is loaded woth software optically. Thus, operating the unit with the back off might scramble the data maakinh the DVI useless.

Later, they come out with a procedure entialing putting a jumper in between two of the connections for servicing.

Now what happens if you want to test the DVI input with the back off ?

I just put a piece of black tape ove the hole.

Reminds me of a joke about a factory with a problem that sometimes the boxes coming off the line were empty. So they hired a guy to watch for that and make sure the empty boxes did not get shipped to their customers.

Well one day he had to go to the bathroo, so he put a fan at the end of the line that smply blew off the empty boxes and let the full ones got through.

Done thunk himself put of a job there...

It's just a part of the overall plan to not have us be able to fix anything anymore. My Visio TV (that a customer left here basically just fell apart when I opened it up. But then how would I have known that it was designed to do that. Took me hours to get all the "layers" realigned and back together. Lenny
