Question about Televison & Video
Hi, you can change the infrared reciever but the problem is getting the part the only real chance you have of getting the part would be to go into your local tv repair shop and ask them to order you one as they might be able to get you a universal one, as long as your 100% sure you can remove the old one and resolder the new without causing any damage to the corcuit board then you could go ahead with doing it.
But are you 100% sure the control is working properly the first thing i would do is take the control apart and give the back of the buttons a good clean and give all the contacts on the board a good clean also as this is the usual cause of the problem your having.
If this dont make no change then you could buy an all in one remote you can get these for next to nothing so try one of these first as you could change the part on the telly and still have the same problem.
So do the control first to make 100% sure that its the telly at fault and not the control.
Let me know how you get on or if you need further assistance ok

Yes , you can replace the IR receiver.
you may need to open the unit , be sure that everything is unplugged
and visually look for the IR receiver.
the IR receiver have 3 important pins to operate.
you may need to use a 30 watt soldering iron and a good soldering
lead . and try to resolder the 3 most important pins
if the soldered joint is shiny , it must be good
and try again on your remote
if it still fails and you need really the IR Receiver it might be similar , is available at
here is the schematic
on V out 1, the voltage reading will be fluctuating from 5V
downwards whenever you press any button on the remote
using a multimeter

Hello, you need to make sure what is broken, the remote control or the TV. To check the integrity of the remote control, you need to broadcast from the remote control while he aimed at the video camera. If you see a flicker of light through the camera it shows the integrity of the remote control. In this case the infrared receptor need to be replaced, he is placed near the stand by light.in a rare case the problem is at the 5v voltage that goes to the receptor. more rare is the possibility that something is wrong at the microprocessor circuit. . If the remote control out of order, can be opened carefully by a thin screwdriver, usually the causes to the error are loose components or contacts that are supposed to weld back into the board.
i hope it was helpful!! Let me know if you need further guidance
