More likely that it has dirty switch that select the front IR receiver or the Rear panel (see page 8) Remote control input that failed to select the fron IR remote, insert a miniphone plug in to the remote input jack in and out a couple times to clean the switch contact, you have to spray the contact clener into the jack. Very common with LG TV.
Let us know if that fix it.

Grinding remote control TP2 not working

light at the remote control flashes; does not mean it works properly. You have to check whether it emits infrared rays out from its front; which activates the TV. The indicator light blinks; means the remote control is working, and the the batteries are good. That's all. The infrared light that emits from its front side [infrared LED] is not visible to human eye. It can be detected by an electronic camera. If infrared ray emitting LED is faulty, the TV won't respond to remote control.
Check the remote control for its infrared emission. Check it by pressing all the keys. You can detect the presence of infra-red emission from the remote control, using a cell-phone camera. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience. In some cases, the remote control might need to clean.

Volume stuck on 0

Check the remote control for its infrared emission. Check it with fresh batteries. If you wish to get more details about how to check a remote control, please visit this site. One among the posts has details about it. Surf the site with patience.
If all other functions, except the Volume + / - button on your remote control works properly, the fault is with the remote controls' keypad. If no buttons on the remote control works, it might be due to a non functional remote control, or with a faulty infrared sensor inside your TV.

Bush A626N lcd flatscreen tv but the remote control seems locked no buttons will work even the standby button we have lost instruction manual, but when you use the buttons on side of tv you can get menu...

you can test any infrared remote by pointing it at the camera of your smartphone, push the buttons on your remote and if it is working you will see the LED on the remote light up on your camera screen. Unfortunately this does not work with an iPhone due to the infrared filter installed in that camera. If the LED does not light, it could need cleaning of the buttons, or repair to the connections on the LED itself.

Not able to program my remote for my new sanyo t.v. It will not blink tv after I touch setup .. seems there is no connection somewhere .. I just installed new batteries


You first check your remote control for its infrared lightup. Infrared rays comes from it infrared LED on its front end in invissible to us. It can be checked with a cellphone which has a camera option in it. Set the cellphone to camera mode. and place the remote control handset in front of its lens about one feet or so away from it, and press each button on it. For each button press, you can see the infrared image on the screen of the cellphone, if the remote contol works properly. Just press the setup key especially for this test, as you says it is not seem to work.
If there is infrared image gets on the camera screen for all button presses, and still your TV doesnt respond to it, your TVs infrared sensor has damaged, and should be replaced. If you want furthermore assistance, feel free to contact me through Fixya. OK.

Remote doesn't work - have new remote - tv doesn't respond

It may have the IR receiver module problem inside the TV. Just to be sure check both old and new remotes:
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera’s Lens (Digital Camera can detect IR), you should see flashing light on the camera’s screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.

Let verify first if the remote is sending out signal, point the remote at your digital camera, you shoud see flashing light on your camera screen (camera can see infrared light) when any remote button is pushed, if you can see it, then the problem can be in the Infrared receiver in your TV and need further troubleshooting.

You can get new remote on EBAY.
