SOURCE: Mitsubishi WS65411. Front panel dead.

 This set has a keyboard lock feature and it can be removed by pushing in the menu button on the front keyboard on the set for about10 seconds. This should take care of your problem.

 Reply to this post if you have any questions and I will respond.

SOURCE: How do I replace the IR remote sensor on my LG TV?

My LG TV stopped responding to the remote. A very helpful repair technician told me to stick a head phone jack in the sensor jack on the back of the TV a few times to clean out the contacts. Now the remote control works fine.

SOURCE: unit does not respond to remote control

I had this same problem with the Onkyo TX-SR706 this evening, and finally found the solution in the "Controlling Other Components" section of the manual: Resetting the remote control did the trick. (P.S. This problem started after I spent many hours today trying to get my new Acer laptop equipped with a Hauppauge TV tuner stick to correctly display its image on my Samsung HDTV, with sound. I tried connecting the laptop via HDMI first to the Onkyo receiver and then directly to the TV, neither of which worked as it should. I assume that somehow, in all those hours of much plugging and unplugging and fiddling around, I screwed up the remote sensor -- thank goodness I eventually found the "Resetting the Remote Controller" solution a little while ago -- I was approaching the point of ripping everything apart and throwing it out the window!)

SOURCE: cable box remote doesn't work when tv is turned on.

I am having this same problem with our Mitsubishi LCD Flat Panel TV, Model LT-46246 ans our Scientific Atlanta remote cable box, same model as yours. We cannot use the remote at all to change the channel. I called Mitsubishi and they said they have never heard of this. I find this incredibly hard to believe. Time Warner, our cable provider says that it is not the box because it works when not hooked up to the TV. What a pain. I would love to hear if anyone else is having this problem or has a fix for it.

I need the exact location of the IR sensor on the front panel of a Motorola DCH6416 cable box.


Do this like mine sweeping. Grab the remote and put it right up to the front of the box. Press the channel up or down keys as you move the remote across the front of the box. You'll get to a point where the box responds well. Then as you go past the point the box will stop reacting so well. Home in to the point where the box responds well. That's your point for the blaster.

My tv [vizio vf550m] won't respond to a remote.


Vizio is famous for having main board issues. If you have replaced the IR board the only two other items it could be is a broken wire from the IR to main or the main board has an issue. Nothing else can stop the remote from working provided the remote is working properly.

Dead lamp


The sensor is located on or near the lamp compartment on the back side. If your lamp keeps blowing it may be the lamp cooling fan not working. However are you sure the lamp is blowing? Press menu and device on the front control panel both in together for 5 seconds and see if the led blinks a two digit code, then let me know the code. Please respond to this same post.

Remote will not function with TV


If two remotes do not work. I would say the IR sensor on the front panel of the TV might be defective.
Can you provide an exact TV model number to try to locate an IR sensor part suppier?
