Simple Remote Control Repair
A customer sent to me his remote control for repair and inside does not have batteries. So I had to use my own batteries to test it.
Once the 2 x AAA new batteries were inserted I pointed the remote control to my remote controller tester (Starmax universal IR remote controller signal tester) as seen in the next photo.
For a good working remote control, whenever a button is pressed the blue LED should light up. But for this remote control, it seems like no response no matter which buttons I had pressed. This means the remote control have problem and it need to be repaired.
In the below photo, when I pressed any button on a good working remote control, the blue LED lit and this means the remote control is sending out signal which was detected by the remote controller tester.
Next i had to open the remote control to see what is wrong with it. The first thing I saw was dry joints in the IR LED.
I had to resolder and clean the circuit board with a contact cleaner before test it again.
Yes, the remote control was working like normal as seen from the photo below. It was a pretty straight forward test and repair. All the best to you.
