My remote control is working near the tv but at a distance its not working,itry changing batterias still not workingnot

If battery in the remote control is weak; this can happen. Repalce the batteries with new ones' and check. Still it behaves so; either the infrared sensor inside your TV; or the infrared lED, that emits infrared rays, is weak. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience.
There is details about how to check a remote control, using a mobile phone camera.

How do i fix my remote

Check it with fresh batteries. If batteries are weak, this might happen. If batteries are good, and still it does not give you distance range, the infrared emitting LED inside it is faulty. To replace it, you have to open the remote control. Check this link. It has details about how to repair a remote control. Pull up older posts. The fault can also be due to a faulty remote sensor inside the TV too. The sensor can be located just behind the infrared sensor window at the front of the TV. Will look somewhat like this.

Remote control won't work 10 feet away but if two feet away it works. What gives?

the remote uses light to send a signal to the tv. make sure there isn't anything interfering with the light signal. it could be dirty or the receiver could have dirt obstructing the light.

Usually on any equipment with a remote---if you hold remote real close and it works you have either a dirty lens for the receiver or a defective infrared receiver in the unit-----odd that moving things would cause this.

If it is only the on/off function having a issue--that would rule out both of the possible solutions I suggested.

Be sure batteries are new/good and no indirect light is hitting front of unit where receiver is located.

Cannot use remote control to switch on TV, but I can manual switch the TV. Guess the receiver board has problem.

If front panel contols are working and set does not works with its remote control, first check the remote control for its infrared emission. You can check it with the help of a cellphone set to camera option. Eventhough, human eye cannot detect the infrared rays, electronic cameras can. Just hold the remote control at about a feet away from the cellphone camera lens, and press each button on it. if there is any infrared radiation comes out of it, the cellphone camera will sense it, and you can get an image of it the screen. If it is there, still the TV does not respond to it, the infrared sensor inside the circuit board of your tV is faulty, and should be replaced with same typw and number. OK.

Tv remote not working

Check the remote control for its infrared emission first. You can check it with the help of a cellphone with camera. Eventhough human eye cannot detect infrared rays, electronic cameras can. Put your cellphone to camera mode, place the remote control [ replace its batteries with new ones]; at about one feet away from the camera lens, and press each button on the remote control. If infrared emission is there, you can see its image on the cellphome camera screen. If there is infrared emission for all button press of remote control; the infrared sensor inside your TV is faulty. It should be replaced with same type and number. If there is no infrared images, the remote control is not working, and should be replaced. Check the battery contacts of the remote battery compartment for any rust or dirt. Clean it well before replacing new batteries into it. OK.

I have a sony Bravia KLV-S40A10E 4 years old.Remote controle device is no ore working. Batteries have been changed without solving the problem .. Other Remote device ( DVD-Sony ) is also not working...

You just check your remote control handset for its infrared emission. There is an infrared light emitting diode [LED], in front of your remote control handset from which infrared light rays are send to your TVs infrared sensor, fitted inside it, behind the infrared window on its front panel. Infrared rays are invisible to human eye. We can check if it is there by using a cellphone with camera option.
Put the cellphone in camera mode, and place your remote control's LED side towards its lens, for about a feet away or so, and when you push its each button, you can see an image in the phones' screen. If it is there, and still your TV don't work with remote control, TVs infrared sensor inside is faulty, and needs replacement.
If there is no infrared image from your remote control, you have to buy one new remote control. OK.

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.

Samsung LN-T4042H 40" LCD

This may not really be a solution to your problem, but here it goes. If you are not sitting a particular distance from your tv you will experience slight pixelation. I have this tv myself and I think it looks great. Now when I am sitting up close on a station that is broadcasting in 720p(which is pretty much every HD station) It looks only pretty good...I sit back and it is fantastic. The good rule of thumb is take the number or inches your TV is in yours and my case 40, divide by 10 and then multiply by 2...and that is the number of feet you should be for optimal viewing distance. So 8 feet, you would be surprised to see how sitting this magic number away makes a difference.
