How to make your remote work when coupled with Samsung Lcd and receiver is in a glass front cabinet

Because the IR part of the remote is so strong with it's signal and some of the features on the Samsung conflict with each other the receiver either works sometime or not at all. 

 

Cheap solution: Make a tunnell out of aluminum foil and place in front of IR eye on receiver. By doing this the signal to the IR eye on the receiver is less consequently what the remote commands sent are accomplished. I have been on uverse since 8/17/13 had the remote problem since day one. I spent time reading about remote problems online and talk about a remote IR repeater. I purchased what the suggestion was did not work for me. By trial and error over a couple of days came up with aluminum foil thought and it worked.

 

AT&T go back to your vendors it is a software problem they should easily fix...

Yes, it has been a long standing problem. Props to you for figuring out a solution. Here is my perspective -

IR Issues

Going back 5-6 years there are many posts about IR interference. Remedies included taping over the IR sensor, hiding the STB, turning off auto brightness on the TV.

A common fault was the info button press corrupting to an STB mute action. The number of reports of this have totally fallen away. My personal initial primary problem was getting the zero to register. But, one day long ago that just went away.

Niles Audio Corp. makes IR repeaters & has a video on their web site showing the fragility of the IR coding that is used for U-verse & other boxes. They said their new line of repeaters could handle it. Oddly, a U-verse customer posted in this community that they had a NIles install that was not working & after they contacted Niles they did not get any satisfactory resolution.

I came to believe that the IR sensor is too sensitive, That the DVR is worse than other STBs. That command type buttons are worse than the number buttons. That, somehow software updates can make it better or worse, So, it is a moving target. Hard to pin down.

I noticed that the U-verse remote does work better than my Logitech Harmony model 700. I looked at the IR signal through a digital camera. It appeared to me that the Harmony IR signal is stronger than the U-verse remote. This reinforces my theory that the IR sensor is too sensitive.

Recently, my most common problem was FF and Play Buttons often corrupted to chan up and chan down more than six times a night while watching recorded shows, exclusively.

I happened to notice that I had a specific kind of "duct tape" covering the blue light on the STB. Actually, it just looks like duct tape, but is electrical tape available at the Home Depot in the electrical dept. - http://www.homedepot.com/p/Commercial-Electric-2-in-x-150-ft-Vinyl-Electrical-Bundling-Tape-Silver-3...

This tape has a degree of transparency. I thought I would use it to cover the IR sensor. The remote has never worked better. In over 20 evenings since I applied the tape - watching recordings while FF through the ads - I have not had one chan up - chan down corruption . Previously, there would have been at least 6x20=120 occurrences.

Almost all button presses are accepted & none are changed to a different action.


RF Issues

It should not be a surprise, but it is, that half the problems with the RF remote are IR. I run an STB well hidden for a second TV. I had the IR sensor covered with black tape. I replaced the black tape with the "duct tape" & saw an immediate improvement in response to menu buttons. The number buttons were already good - see below for that solution.

The STB using RF must be hidden due to the dongle conversion of RF to IR. If it is not hidden it is subject to the following problems:

IR corruption - Ironically, the RF remote was often offered as a resolution for IR problems. But, if the STB is not hidden nothing has changed to eliminate theI IR corruption problem. If the corrupting light can be seen by the STB IR sensor it will continue to corrupt the IR signal.

If the STB IR sensor can see IR from another remote, it will respond to it.

If another STB can see the IR generated by the dongle, it will respond to it.

Note that hidden means the IR does not see outside light - If you have an optical repeater it is IR subject to corruption. If you have an IR receiver that produces RF to go through a wall, it is still IR subject to corruption. Only if the remote is RF (like the point anywhere remote) transmitted to a hidden device will it ward off IR corruption.

Previously, I found the RF remote lacking in RF power - in the same room, twelve feet away, hidden only by a thin sheet of cardboard. One method to increase RF power is to hold the remote under your chin while pressing a button - using your head as an antenna.

A better way is this antenna placed in the battery compartment - http://www.amazon.com/Cellular-Innovations-A-BOOSTER-Universal-Antenna/dp/B00009WCAP/ref=sr_1_8?ie=U...

With this antenna, the channel numbers are almost always accepted. With the "duct tape" in place, the other buttons work almost every time. The remote now works better than ever.

STB Issues

Once IR and RF issues are resolved, there are timing issues with the STB to contend with. Numbers process fast and Menu items process slow. You need quick, light touch on some numbers to avoid duplicates and a slow, strong press on menu activities. Effort is required to suppress the urge to press again while waiting for a response. It takes concentration to get effective results. Frequently a second press immediately cancels a slow responding first press. Current IR and RF issues amplify the effect of the timing issue.
