Set top box and remote control

I have a scientific atlanta explorer 8300hdc set top box that comes standard with the universal electronics remote control 1056b01. the set top box will not respond to the remote control. the box is good because i can select guide and change channels. please help. OK, I thought I was losing my mind until I read this. I hooked up my SA Explorer 8300HDC and could not get the remote to work when the TV was on. Come to find out it doesn't have to do with power to the TV, but the screen, when the screen is on, the remote will not function on the cable box. I also found that turned the cable box to angle away from the TV, while the TV is on will allow the remote to work. There must be some type of interference between the LCD screen being on and the remote. Please help.

    I have the identical problem. When I use different DVRs I still have this issue. I just switched to DISH and it still occurs. As mentioned, angling the DVR unit helps to mitigate the effects of the LCD.

    I was able to solve the issue I had with the remote not functioning with my LCD TV. The problem turns out to be the IR that the TV emits causes the remote not to function. I did a little research to discover the fix was a simple as a piece of tape. Yes, that is right a piece of tape!!! Simply putting a small piece of tape over the IR eye of the cable box, acts like a filter and allows the remote to still work, but blocks the IR emitted from the TV. Since the fix, I have had Comcast at my house on another issue, and mentioned the problem to (2) techs that were there, they had never come across the problem, which did not surprise me, but I did offer them my solution. Just for the record the IR eye on the cable box is to the left of the time/channel digits, by using a flashlight you can see the small red circle, and by using a small piece of black electrical tape over the IR eye it fixed my issue and doesn't show.

    Have the same problem with LCD 42LG2000 and a motorola set-top box (VIP1920). I would rather prefer tech support solves problem instead of gluing some tape... Sent emails to Motorola and LG now I'm waiting for some answers...

    F'n genius! The tape trick worked for me. Are new TV IRs on steroids? wtf?

    A box is displayed in the center of screen that reads "The update includes improved remote performance and functionality" with a "start setup" button but you cant select start. Also, the remote lights will not go off and the remote doesnt work at all. It will not even turn the tv off.

My remote wasn't working until I programmed it to work with itself ... (how odd it wasn't done already).

"CBL" button and ""OK/SEL" held down simulataneously for 3 seconds ... then "001" for the Scientific Atlanta. If the unit turns off, you're in business.

My DISH DVR unit has a UHF antenna to work with the 2nd TV in another room. When I asked DISH tech support if this could be used to also support the remote of the primary tv (the LCD), they said they have a UHF kit for $19. I bought the kit, and now both my remotes (TV1 and TV2) are UHF and work perfectly.

The best thing to do is to move the receivers or TVs to a location that separates them with a greater distance.

Set top box and remote control

I have the same problem. When I move the 8300HDC away from the TV, or power off the TV, the remote responds. There seems to be some kind of RF interference, which makes no sense since the TV shouldn't emit RF, and the the box should be using IR only for remote input. My TV is a 46" LCD Samsung. Try turning off the TV and see if the 8300HDC responds to powering on and off with the remote.
