Green light blinks, infrared led do not work

Post by jniezgoski »

I'm not sure what's wrong, the green LED blinks when pressing the button, however the IR LEDs and the function of turning off a TV doesn't. How can I test this? I checked 3v from pin 3 to 6, recommended from another site. Solder joints look clean, I had an issue bending those 3 pin resistors to the LEDs but made due.

How can I fix or check what the problem is with a multimeter?

Try watching the IR LEDs through a cell phone camera when you push the button. Those can usually see IR, so at least you'll have some idea whether the LEDs are lighting at all.

I just checked, I don't see it light up. I soldered the LEDs to the back pins instead of the front board where all the components are on - is this correct or would have an issue with the setup I have it?

Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.

The solder joints for the LEDs could use some work. I can see gold from the pads in a couple of them, which is often a sign that the solder hasn't made good contact with the metal.

Give each joint a dab of flux and reheat them. You want a smooth, shiny cone that covers the pad and sweeps up smoothly to the lead.
