We have a pioneer pdp-6070pu plasma tv - it was in trap switch mode - we did the procedure - get to the initialize page of the factory menu - then cuts off - the red led light on the main board is on

Pioneer PDP 428XG Operating Instructions Manual

Brand NEW Pioneer Plasma television Remote Control AXD1554 PDP 428XG...

The Media Receiver is the tuner/connector selector box.
If the top is removed the Media Box goes into shut down mode. It requires resetting by a Pioneer Authorised Service tool.

try a full factory reset then check to see if someone has turned on the mode or channel block, some tv,s you can block the dvd mode through the parental guide lock

Do a factory reset to this set and proceed. Refer its user manual for details.

Try restting it by unplugging the tv for a few mins and it should rest to original factory default settings but leave it unplugged 10-15 mins to be sure.

Hello
Your Tv may be misadjusted by any way I thinks. Set all the modes to factory defaults. To set it to factory defaults do the folloing:

1 Press HOME MENU
2 Select "Option with (UP or DOWN button then ENTER)
3 Select RESET with (UP or DOWN button then ENTER)

confirmation screen appears. Press [ => or then press ENTER

This process will reset all the parameters to factory set levels. You have to adjust the Parential controls and other parameters by yourself later.
OK

Hey,
This may be too late...
I got it from the field manual.

Trap Switch Reset Procedure
G-4, G-5, G-6, G-7, G-8
• Replace media receiver, plasma panel cover, or tape down HDCP trap switch.
If the model in question has the TV Guide option, the TV Guide
option must be turned off before proceeding.
• Using the customer’s remote control enter “service mode” by pressing the
following key sequence:
1. Press the “display” button then release the “display” button.
2. Wait between 3 and 7 seconds
3. Press and release the “<”, “^”, “<”, “>”, and “power” buttons in sequence.
• Panel will now turn on in “service mode”.
4. Press “muting” button 3, 4 or 5 times depending on model you are working on.
Until the display shows the “initialize” page.
5. Press and hold the “display” button until the error indicator (red LED) on
either the panel or the media receiver goes out.
6. Exit service mode by pressing the “power” button on the remote.

I had to try it a couple of times before I got it to work. I.m not too sure how to turn off the tv guide mode. I just held it in for a couple of sec,s.

Good luck

I would assume the power board has a problem. A tech could possibly repair it without replacing the whole board.

you have tript the trap switch. there is one in he panel and one in the media reciever.you have to enter the technicians code followed by pressing the mute button 4 times then the display button. this should reset the trap switch.i presume you have put the cover back on. if not you must tie down the trap switch which you will see facing up
