So today I noticed the red light is flashing. At first I unpluged the TV from electricity for a half an hour, but it still was flashing. Then I did a reset and it still is flashing. This video is filmed after reset. And accidentaly I noticed it stops doing it when something is put in front of it. What could be happening? I also tried to put a remote away - maybe a button got stuck, but no luck - it is flashing even if batteries taken out, and remote covered in tinfoil. Any help would ve much apriciated!
As mentioned by others, it is likely picking up IR from something in the room.
When you use the TV remote, it should flash each time you press a button, often very quickly like when you press and hold Volume +/-.
When you are not using the remote, and it is still flashing, I would be looking for something else in the room that might be sending a blast of IR.
Most older TV's are not smart enough to have two way communication with a remote to know if the batteries are weak.
What type of lights do you have in the room? Does it still flash when they are off?
Do you have other equipment located close to the TV, possibly a cable or Sat box with a hard drive?
You have to start looking around and if need be, turning other things off to see if anything might be the cause. This should include checking any other remotes in the room to see if a button might be stuck down.
What make of TV is it? The part that flashes looks more like an IR repeater you would attach to the bottom of the TV when your gear is located behind a cabinet door.
And if it was one of those, I would ask if the TV is an older plasma TV, as they often messed up IR repeaters and you had to order specific ones to work with Plasma.
What Philips model is that?
Older fluorescent lights used to emit light that overlaps into the IR spectrum at near 40khz (frequency used by some IR remotes). In fact, many of the companies that sell IR repeaters have special "fluorescent immune" models. Any chance there is a fluorescent light within view of the TV?
If you open your phone camera and look around the room you should be able to see IR LEDs flashing to help locate what is constantly firing signals that your tv is receiving
You are a wizard, Harry.
You have a remote somewhere sending signal to the TV. It's IR signal or it wouldn't stop when something is in front of it. It may be a cable box remote, video game remote, or any other kind of IR remote. I'd test by taking batteries out of anything that resembles a remote, then add them back one at a time. Good luck.
