remote control circuit

i have 2 damage electronic boards of panasonic fan same siries, but i don't know which component not functioning. the fan still roting but can't follow the romote control task

Hi
Lets have a model number and schematic then might be able to help you

Have you try any similar fan with that remote to assert it's workability?
Go to the fan IR receiver sensor and find the pins from data sheet. Read the I/P and O/P voltage on pressing ur remote.

Hi..
I think IR receiver might got faulty or your may be remote... to check the remote Just use a cellphone camera and press the button of remote. if you could see IR light in the camera then remote is OK and only the fault lies in the receiver.

Contact Panasonic direct and find out if they have the schematics Panasonic are always helpful with regards this

The other attack to this problem is check your remote first

The easy way to do this is point your remote at a webcam or a mobile phone camera any security camera which you can view then key the remote

If it’s working or a good indication that its working then is visual flashes from monitoring the camera, TV monitor , front of phone if its a mobile phone camera and you can then see the led from the remote control working

Should be easy enough for you to do
