Post subject:  Infrared Interference by your Flatscreen (Reference)

I had been experiencing a lot of crashes by the Mythbox in my family room. I was doing a lot of 'work' on it and attributed it to that. I changed it out for a Mythbox that had sat under my desk and run like the sunrise ..... until it resided in the family room,where it crashed three times in a week !

Both boxes have Streamzap remotes, and receivers... which blinked inexplicably.... but I didn't figure it out at the time. I couldn't find any stuck remotes.

Some glimmers came when a new Dish settop box was installed & I had trouble with the remote responding on it. A google search turned up that IR tossed off by your flatscreen (particularly during warmup) causes remote problems for a lot of people, using boxes operating on IR frequencies different from the ones the TV remote uses....

A reason for crashing Mythboxes began to formulate... I banished the crashing problem by banishing the IR remotes and using the Mythweb remotes.

Fortunately, the Google searches provide a solution that works: Masking the IR receivers windows with an appropriate number of layers of printer paper (one worked for me...)[The Dish box started responding too...] The background IR is blocked but the beam from the remote gets through.

So if you are having mysterious problems with your Mythboxes or remotes ..... :lol:

I had an ifrared keyboard for the last 3 years randomly when i adjusted the volume on my Onkyo receiver it would cause the system to lock up requiring a hard reset.
My daughter has this bouncy horse thing that interacts with a box that is plugged into the TV. When that horse is turned on no remotes work at all. It blasts the living room with signals.

Flying an infrared controlled helicopter in the same room as a Mythbox will crash it (the box... not the helicopter.... :lol:

I've seen the TV interference issue particularly with Plasma TVs not with LCD yet in my experience. That's why I went RF instead for a front end I have that is near one of my plasma TVs.

The Google provided material makes clear that plasmas may be worse, but LCDs are offenders too...esp. some models (like mine..Sharp...)

I got one box controlled by an RF Firefly, but it covers the entire house, so the other boxes have to be IR... Streamzaps and Hauppauge Silvers.... :lol:

Indeed! I have one of those on the front end the kids use the most. I use Harmony 890s on the other front ends. Works really well.

It's too early to tell for sure, but this might be the best little tip in months. A simple piece of white paper as a hood around the IR sensor for my old keyboard, and not an error or a dropped keystroke to be seen. Unbelievable...

I was surprised that I hadn't seen anything about this here before...

I think we're geared to look for problems in the software too much ! .... :lol:
