Does anyone have the discreet on/off code for the Panasonic 37" plasma? model # (th-37pa20) If so could you PLEASE publish it. Thank you in advance

Jeff


Ps: I was also looking for the discreet code for the sleep timer options menu.

This has probably been one of the most discussed topics here. If you "search forum" and enter +panasonic +plasma you will find a great deal of relevant information. IIRC, the answer is very model specific.

Rather than start my own thread I thought I would
bump this one. How dumb can Panasonic be?
Is it really possible that they could have released
their latest generation Plasma's without discrete ON
IR codes and then leave their customer support people
so oblivious and uninformed on the subject.

I bought the TH-42PX20 because it had the best price
performance ratio out there in 42" plasmas. I don't
really regret the purchase, it is a great TV... but,
if the thing really doesn't have a discrete ON command
I would really like PANASONIC to own up to it and
issue an appology. I don't think anyone bought these
sets for a low-end home theater and I think everyone
who did buy one would probably not buy a Panasonic
product again because of how they have handled this
issue (or let say ignored the issue). So, Panasonic,
do you hear that, do you get me? I will never buy
another Panasonic product because of how you handled
this.

I found your manual

[Link: panasonic.ca]

to see if it had RS-232 control (It doesn't appear to) but I did see something called Auto Power On on p.29 that can be selected in the setup menu, that I assume when it senses the presence of a live video input it switches the Plasma On.

You might experiment with that and if you have a DVD that has a discrete On command that may work. I suspect that all video inputs would have to be Off and if your STB (set top box) doesn't have a discrete off then you might need a Video switcher to interrupt the video in order to make this work. It would be interesting if it auto-switches to the live video input as well

Unfortunately the Auto Power On function isn't that (I wish it was), it turns the set on when the AC power appears.

I use this -- I hooked the Panasonic through a Niles AC controller which powers it on when it senses current flowing through my SAT tuner or DVD player. So I get discrete control this way. I'm not thrilled with it but it works after a fashion. The Power On/Off toggle for the display will still operate, which can defeat the whole scheme (if it's powered-off the Auto Power On won't turn it on).

Also, I couldn't use a TiVo box to trigger the current-sensing device -- TiVos draw unpredictable amounts of current, there's no clear difference between "on" and "off".

Mine is a TH50-PX20. I was lucky enough to get the Niles box on eBay for about $100. For now I guess it's OK.

Hmmm, I traveled 3-1/2 hours to do a setup including a 37" Pana plasma.
The discretes database here had separate on and off functions, but only the off worked. On function was no good.
I ended up with a power off then back on macro. Dumb, but the only way.
It only really turns the thing off and back on when switching to a different input - from a cold start it works fine.
Dumb.

BTW, someone posted this site for discretes. Maybe you can browse there and tell us if something works. I'm too far away to experiment with the 37" I installed. I'd like to know if there is a solution out there.
Thanks!
