How common is it for an ir sensor to go bad? I've got an HR22 and cannot get any response from the remote unless I'm a foot away from the sensor on the front of the receiver. I've done a RBR on the unit and tried with 3 remotes, all with the same results. Before I make a call in to a CSR what are the chances they'll say that functionality of the unit is operating as it should and the convenience of the remote won't get a replacement unit sent out.

Not sure about the TV being an issue in any......... Thanks!!

Had a book laying on top of my surround sound remote causing interference. Getting new siding on the house and the estimator left the book of samples to look over and it got put to the side when the wife was done looking at it.

Your suggestion got me looking for remotes and found the above.

Florescent back lit LCD TVs can also interfere with IR.
DirecTV since '96, Waivers for ABC, CBS, NBC, & Fox, HR23-700 & HR24-500/AM21, using ethernet based MRV.

No problems with the back lit by LED LCDs? I saw a monstrous 80" Sharp Aquos a couple days ago and it had a pretty good picture on it. I was surprised.

There's no problem with LEDs. It's the switching power supply for the LCD backlight that creates the interference and LEDs don't need one.

Drifting off-topick, seen in Costco the 80" monster (isn't time to measure TV screen by feet ?) - looks appealing, but the $5000 range is not what I'd like to see.

Wasn't in Costco and it wasn't as expensive as I thought it would be. Don't remember the exact cost.

A nice bandaid for the LCD back light issue is Blue painters tape over the IR sensor. The problem is prevalent with Vizio tv's and it's actualy part of thier steps to resolve the issue. I'm not sure on the exact details but has somthing to do with the tape filters out enough of light from the TV the receiver can deal with the reset and the remotes stronger signal at that point works again.

Interesting. Noted that another remote can cause problems with our units.... if there button is being held down..

I was having a war with one of my neighbors who just bought a wireless door bell, the same model I have. Don't know who it was, but he kept ringing my door bell and I kept ringing his door bell and a lot of time passed. When I went out to go to the store, my car dongle was dead. Nothing worked. Had to drive for a while to get it working again. Never gonna do that again. He won.... :lol:
