Your board isn't defective, it's in factory test mode, and you have to disable it.
The problem is that there are several ways to disable it, and I have to figure out which way disables your TV factory mode.
Hmm, off the top of my head, I think you have to press the ACTION button on the TV set for 10 seconds until a Check - OK list pops up, then you press the power button on your TV set AFTER it pops up.
That's one way.
Worst case scenario -- I may have to contact Panasonic directly on Monday to get the correct shutdown procedure for you. Can you try that one I gave you, and get back with me if it doesn't work?
If you have any questions, just ask
Tips are greatly appreciated !
Oh, it is the DG module that has the micro on it, and it is the service mode.
One problem I've had is figuring out how to deactivate the service mode, because the exit command isn't written out too well in the service manual. They could have done a better job there.
But a phone call to panasonic always seems to correct the problem.
Panasonic will ask me the model number and the serial number, so if you can get me BOTH, I would appreciate that.
As for the ACTION button, it's most likely the OK button in the middle of the arrow keys.
Here's some other possible Service mode deactivation keys --
Try actually activating it first, then try deactivating it. I know the service deactivation mode has always been a pain to do, they just need better technical writers for that part.
Simply unplugging the TV or pressing the power button for 5 seconds has never fixed that. You have to HOLD DOWN a button on the remote, and the volume button, then it switches over to the module check page, with the OK listed. Then you can turn it off.
You may want to try the OK button on the remote and the power button on the TV for 5 to 10 seconds to see if the CHK message disappears and you get the module OK page....
Then you can hit the power button again.
When you advance to the highest level like I am, JA and I split the $28 deposit 50/50.
Tips, I get 75/25 on that.
Now, I assume ONE of those worked?? Which one? Like I said, the Panasonic instructions on how to deactivate the service mode leaves a lot to be desired.
OH, I didn't see your first posting before the last one ! So holding down the OK button, THEN pressing the power button got it out of service mode.
SO FORGET THE REST OF THE POSTING BELOW, and THANK YOU for accepting !
So all I do know is that you press a sequence of buttons like Volume down on the front panel and the Action/Ok button or the Menu button on the remote for about 5 to 10 seconds, then the page with all the OK boxes pop up and then you know you have properly exited the service mode, and now you can either hit the power button or unplug it.
That's why I have to call Panasonic -- their instructions are horribly written in the service manual about how to exit the service mode.
And if you haven't got it deactivated yet.....get me a serial number so I can call them MONDAY, ok?
Let me know.
