Lcd tv not receiving remote control signal

I have a 19" acoutsitc solution lcd tv (from ebay, i month ago). the remote control only works for a couple of minutes and at random. It is not a remote control fault, because after changing the batteries and installing an av sender, i can see the av sender blinking every time i try to use the remote. so the problem seems to be with the tv itself receiving the signal from the remote. i've wiped what i thought was the sensor area on the tv, but no luck!! it's really frustrating....can you help at all?

VW37L 37 in. LCD HDTV input button wont work


Have you find out if the problem is with your remote control? For instance, you are able to control your TV using a Universal remote control. My 32" Vizio TV had a similar problem, initially thought it was related to my remote control but in fact the TV didn't respond either to an universal remote control of my SAT receiver that I eventually use to just turn on and off the TV. I've found out that the problem was with a little board on the TV located at the left down corner viewed from the front side of the TV and that receives the signal from the remote control. I found the board on ebay for about $5, replace it and the TV responded again to both original and universal remotes.

Hi I have a Aldi bauhn LCD tv and its not recieving the remote signal. I have checked through a camera for the remote control light signal and it works with every button. So that leaves the reciever


Will cost more to fix then a new unit , replace it and try to buy a extended warranty with the new one, most times you can get 3 years after the original warranty runs out.

Broksonic 19 inch CCVG 1935 - no sound, no picture, just a blue screen


Blue screen means either no signal (if unit has rear connections hook a DVD etc to one and go to that input and see if it works) Or the blue may mean set is in shutdown----5 months old and it should still have a warranty?

My remote has stopped working


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.

Goog day. I have a Samsung LE40A559 LCD TV and about a week ago it stopped responding to the remote. Remote itself is working as when the TV is off and I push buttons on the remote the blue light on TV...


The flashing blue light shows that the TV is receiving I.R. from the remote but doesn't mean that the signal being received is recognized by the Samsung. If you have a "universal" remote then your TV code may need to be re-entered/reprogrammed...changing batteries in a "universal" will usually require it to be reprogrammed.

Also...because of the remotes construction (rubber membranes with carbon dots that short across PC traces) I've seen certain buttons stop working altogether.

Channel Up/Down button quit working on the remote control


I had the same problem. You need to go into SETUP > CHANNEL > SKIP and select NO for every channel with a signal. A few months after we purchased the TV it defaulted to this (software glitch). We had lived with it for months before figuring this out. There is no easy way to reset these that I know of. I literally had to go to each channel and then change "skip" to "no." JM

Controls not working on Philips 28" TV


We had this problem with a 28PW6515. The control would work for 30 seconds after switching on, then nothing. It was diagnosed as the "glue chip" which handles all the control functions. About £200 to fix it as it's a surface mount chip.
