Have TV Questions? Ask a TV Technician
The remote will not work on my LG 32" flat screen TV. I have replaced the batteries and still nothing. Someone suggested there may be an update that I could connect and download into the TV? The Model # is 32C70-UB.
Can you please advise if this is a major problem or something that can be easily remedied?
It would help us to know:How long ago did you purchase your TV?Alan, the first thing we will need to know is if the remote control is the problem or the remote receiver on the TV is the problem.
Is this the original remote that came with the TV you are trying to use?We're looking forward to hearing back from you soon!
I see you have gone offline before we had a chance to communicate so I will go ahead and give a simple way to test the remote hand unit, this is a way you can tell if the remote is working or if the receiver in the Tv is at fault. Using a digital camera or a camera on a cell phone, turn the camera on and then point the remote control at the camera lens about 12 inches from the camera. Press the power on the remote as you watch the screen on the camera, you should see a white dot appear on the camera screen. It may be flashing. If you see the white light (dot) then the remote control is good and the problem is with the TV. If the white dot does not appear then remote is faulty and you will need to purchase a new remote. I am assuming you are using the original TV remote and not a universal or generic programmable one.
If you need to purchase a new original remote they can be found here.
If you have any questions or need further assistance with testing your remote or you are not using the original TV remote, please reply and we can continue until we find a solution for your problem.
I have performed the test and do see a white dot, what's next?
Ok, that fact that you see the light on the camera screen is good indication that the remote is working properly. The problem is with the IR receiver on the TV. There is a small circuit board where the IR receiver is mounted on that will have to be replaced.
It is not a difficult repair to make but the unit does have to be taking apart for the circuit board to be replaced. One other thing, make sure that there is nothing in front of the TV that is preventing the sensor from seeing the signal from the remote control.
Is the unit less than 1 year old?
Ok then, there is no easy reset or fix that I can give you, by our chat it seems the remote control receiver has failed. This is the receiver that picks up the signal from the remote hand unit when you press a button. Usually these circuit boards are not more 50 dollars or so but the labor to install will depend on where you have it repaired. I can't see it costing more than $150.00 to have it repaired if you bring it to a shop. A home repair will be more with travel fees.
Any local shop should be able to handle this for you. I am sorry there is not something easy that I can tell you to make it work, it's electronics and sometimes they fail.
