New plasma TV interferes with serial LIRC

[Larry K]

I have a Myth Frontend that has been happily working over S-Video to a 27" Panasonic CRT TV.  Recently, I bought a new Panasonic 50" 50PX77U plasma, so my intent is to connect this display using DVI-HDMI, rather than S-Video, for obvious reasons.

Anyway, since I have not yet configured xorg.conf for DFP output, I simply plugged the S-Video cable into the new plasma as an interim measure.  When I did this, lirc started behaving oddly.  It just does not respond to my remote, and when I run irw to test it out, it very rarely (if ever) picks up the command.  If I simply unplug the S-Video cable from the plasma and put it back on the old 27" CRT, everything returns to normal.  Here, irw echos each and every command flawlessly.  Mythtv responds flawlessly to my remote control as well.

I have come to realize that the plasma TV is creating sufficient infrared interference to disrupt my remote control operation. 

Any thoughts on what can I do to correct this?  Some sort of filter?  Should I try a different IR receiver?  I use this one now:  http://saturnpc.com/index.php?main_page=product_info&products_id=1

Would an RF remote control be a good solution?  Any particular model?  Not sure how well this works with lirc, but I have read that it does in fact work (it does seem curious that RF works with lirc since lirc stands for linux infrared :) )

I had this problem on my dad's television, as well as mine.  For my dad I actually bought a different IR reciever that stated that it was designed to work with plasma tv's, and it worked great.  For me I was able to put my reciever about 3 inches below and 6 inches back from the front of the plasma tv and this worked great for me, but when I was originally on the same plane or in front of the tv screen it was all sorts of messed up.

Hope this helps,

Matt,

Thanks for the reply.  Can you point me to the plasma-friendly IR receiver?  Where did you find it? 

Thanks,
Larry

Larry,
Try placing a peice of scotch tape over the IR reciever.
This tip has been floating around on the AVSforum for some time.  While it
doesn't work for everybody it did solve a similiar problem for me.

Go to accessories, and then to ir receivers and you will see it.

Thanks.  I'll try it.

I am finding some interesting possibilities when I google for "plasma-proof IR receiver".  For instance, http://www.xantech.com/InfraRed

The problem is that these receivers, from what I can tell, use a 3.5mm jack (instead of serial or usb) and expect to be plugged into an IR connecting block.  Other than getting this plasma-proof receiver, a connecting block, and an emitter attached to the connecting block (this puts me back to square one since that emitter has to talk to something), is there any way to hook this kind of thing up to my myth box?

What I really need is a plasma-proof serial or USB IR receiver, but I have not found one of those yet....
