Cable Remotes Lose coding?

Since my answer to your other post didn't help, try this. Admittedly, this seems a bit illogical, but I have fixed many, many glitches in communications equipment by methods that seem illogical.

Anyway, swap the remotes. Bring the one for the Sharpe to the U-verse receiver for the Sanyo, and vice-versa. Manually reprogram them to their respective new sets. Then see what experience you have over time.

As I said in the other post, I've never experienced anything like this in 18 months with three U-verse remotes, so you have something going on there that's way out of the ordinary. If the swap trick doesn't do it, it's time to call U-verse tech support, 800-228-2020, and get to the Tier 2 tech as quickly as you can. The guy that answers will ask you a bunch of inane questions and give you stock answers that won't help. Good luck.

Problems Due to Interference

Symptoms for the following may range from no, intermittent, or incorrect response or greatly reduced range to the equipment being possessed - a TV changing channels, volume, or powering itself on and off as though being controlled by a poltergeist. (Where the problem is due to more than one piece of equipment interacting, see the next section.)

These are likely possibilities if you have just changed your room layout or added something to it:

Interference from another remote in the same room which is defective (or is being squashed by a gorilla). Make sure there are no other IR transmitters including those like the a VCR+ or remote repeater that might be activated accidentally due to faulty programming or something pressing on the buttons. Do you know where all your remotes are hiding?

A neighborhood kid (or adult with the maturity of a kid) may be playing tricks on you from outside your window or even across the street. It doesn't take much (a lens) to extend the effective distance over which a universal remote will operate reliably.

Cover the sensor of the misbehaving equipment with a piece of black tape to see if the problem goes away. Then round up your other remotes (and/or other animate objects) and discipline them!

Fluorescent lamps using electronic ballasts - These may be newer ceiling fixtures or the energy efficient compact fluorescents used as replacements for the regular light bulbs in table lamps. The electronic ballasts are switching power supplies and these may result in modulation of the light intensity at high frequencies confusing the remote control receiver.

Turn off all fluorescent lamps to see if the problem goes away. A cardboard baffle can be taped to the sensor to block the interfering light. Try a different brand of compact fluorescent as not all cause interference.

Bright lights in general - Enough ambient light, be it from the Sun or a 1000 W flood may overload the sensor. Ceiling fans can sometimes modulate the light with their fan blade rotation or vibration of the filaments of the bulbs which can confuse the remote control receiver and microprocessor.

Turn off the lamps or move the Sun to see if the problem goes away. A cardboard baffle can be taped to the sensor to block the interfering light. Simply changing the orientation of a lamp shade or slightly moving one of components may be all that is needed.

Electrical interference from nearby equipment. Inadequate shielding in the sensor electronics could result in susceptibility to RF emissions from other gear.

Turn off suspect devices. If the problem goes away, they will need to be moved to another location. Shielding is probably not a viable option.
