    Sharp Aquos here.

    Once it warms up, remote works like a charm.

    Only problem is when TV is first on.

    I have a Pioneer 6070. Absolutely no problems with the S3 remote.

    Lawrence,...
    I wonder if the protective plastic that's on the S3 front panel when it comes out of the box attenuates the signal in a manner similar to the plastic wrap?

    I had the problem with and without the plastic wrap--the only solution for me was to partially block the sensor.

    I did it externally with a small desk thermometer--but any small object would probably do.

    I thought perhaps a picture on the wall opposite the T.V. and Tivo might be causing the reflections--so I removed it--still the same problem--

    only partial blocking worked.

    My guess is a hardware fix but who knows?

    I am using the latest Tivo software.

    Is it my imagination or do others think that the pic on the Tivo is FAR superior to that on the Comcast Motorola box.

    Finally--
    I just attached a small circular piece of opaque material to the outside of faceplate to cover the sensor--

    Works like a charm

    All the Tivo engineers have to do is send those of us who are having problems a small sticky to attach to the faceplate and it will solve all our problems.

    Wake up Tivo!!!

    FYI,

    I spoke to TIVO support yesterday, my RMA has still not shipped. I asked whether there was a factory fix for the remote control issue, and he stated that he had a notice to that effect.

    Honestly, you'd think the chances of a RMA solution fixing the problem right now is pretty minimal.

    From the way things look, it's a design problem. I'm waiting for Tivo to actually fix it by changing the hardware, cover, or something before I'm calling in for a RMA.

    I still have had zero problems with my S3 sitting on top of my A/V cabinet about 4 inches below my Pioneer 6070 plasma. So I'm unclear about the "design problem". You would think that this would be worst case scenario wouldn't you?

    We are all happy for you. However, this information has not caused my S3 to work any better in the credenza below my Panasonic 657UY. My case remains open with TiVo with no response.

    I wasn't trying to dismiss your problem. I'm just pointing out that this doesn't seem to be a universal issue. And the fact that mine isn't having any problems in a very similar situation might actually HELP you narrow down/troubleshoot your problem. But I'll let you figure it out yourself if you don't want any help. Good luck.

    Sorry, I did not mean to snipe. I do not think we can conclude anything but a design problem. I have six devices with IR receivers that work properly in the same environment. I have opened it twice added glad wrap and I still get ocassional double entry on numbers and missed remote keystrokes. It is much better, it was unusable as shipped.

    I guess we get pissed off at TiVo for not responding in other ways. I think an acknowledgement of some kind like: "we are aware of the problem and working on a solution".

    I can handle that issues like this can occur. Customer support is lacking.

    BTW, I am a lucky 200. They sent me an email 2 weeks ago that I would be receiving a TiVo bag. Nice touch. Of course, I have not received the bag :rolleyes:

    it depends on the backlight used in any one particular brand model of LCD. So I also suspect that the phosphors or coatings or glass(with whatever filtering properties) on any one particular model or brand of plasma matters. If you search the net, it's a widespread but not universal (as you have concluded yourself) problem.

    No sweat. I just wonder if it's your particular S3 unit. It would be nice if you could compare another box, or better yet if we were close by, I could bring mine over and see if your TV gave my S3 problems or if your S3 would work with my TV. Just seems odd that it's not more universal. Seems like if it were your TV that none of your other IR devices would work either.

    Rich and I both have plasmas, not LCDs, so there are no backlights. And my particualr brand of plasma (Pioneer) even removed one of the glass filters a couple of years back, so I would think mine would be giving off even more interference than Rich's, but I could be very wrong about that.

    I saw you have a plasma an i know they have no backlight- that's why I said I think there are still variables with those too.

    Not knocking anyone's plasma (I can't afford any of them-LOL)- but isn't yours (the pioneer) the big dog on the block? It would not be illogical that pioneer does something on their end with the phosphors or the glass to get rid of the problem so their customers never have to deal with it. If it's a $10 IR blocking coating in the glass then a top of the line company might be adding it but someone that is seleling more of a commodity type high vloume unit might not.

    If people want to see- dig up a sony nightshot camcorder. Turn on night shot with the room pitch black, then fire up the TV with a BLACK screen. The whole frigging room will get lit up like fourth of July fireworks if you have a problem. It's very obvious when you see it with your own 2 eyes through the nightshot IR CCD's "eyes".

    Apparently some IR receivers filter that IR noise out better than others- so thats why some devices right next to the tivo's work fine. So it could be that some tivo's have a IR pickup with slightly differnt characteristics and might help, but I would guess that in general they part(s) they speced are more susceptable to this type thing. I am no engineer but it sounds like the reciever can eitehr filter the the spectrum to just get the right wavelenght from the remote and ignore the rest or they use electronic filtering to raise thje threshold of what is considered "on"

    Another basic fix that worked well, at least for me, is to take a small piece of black electrical tape (or any opaque tape - black just looks best) and stick it at the FAR RIGHT of the faceplate, right next to the buttons on front. This brought my success from about 30% with a lot of double hits to 90% with no double hits.

    There is no reason this should work since its nowhere near the sensor, but it worked on my moxi and it works on the tivo for some reason.

    That said, I just shifted it a bit further back in my cabinet and now it gets about a 90% success rate without any tape. This is with a Panasonic TH-50PX60U plasma. Just an idea for those who don't want to open it up. It may only work in my particular setup.

    As I mentioned in a previous reply--

    You don't have to open the box

    Just block a portion, or all of the sensor--start with an external object and if that works, you can get a piece of opaque material to stick on the face plate--

    I have a Panasonic plasma and it works for me--nothing else did.

    The sensor is located on the far right next to the buttons. Shine a flashlight on it and you will see the circular hole.
