LED not working

[matrix1791]

I recently made my tvbgone v1.2.
I made some changes to the parts required-
I used a 8MHz, 2- pin crystal oscillator instead of a resonator.
The device works properly but on seeing through a camera I found that only one of the IR LEDs are blinking. I checked the LEDs, they are not damaged.


Where do u think is the problem?

did you make it from a kit or from parts you purchased?

[matrix1791]

I purchased the pcb and the microcontroller from adafruit.
Rest of the parts I bought separately.

are the parts exactly the same as the ones we supply? did you double check vs the parts list?

As I said I used a 2-pin 8MHz crystal oscillator instead of a resonator.
I used a PH2907, instead of the PN2907 supplied with the kit.

Rest of the parts are same.

we can support you if you have precisely the same exact parts from a kit you bought from us, what you've outlined is not something we can support since we did not supply those parts, sorry. it's not fair to the customers who bought complete kits from us with parts we've tested and documented. you're welcome to post in the forums, we just cannot guess what could be happening with unknown parts as you can imagine.

How did you check them?

Perhaps the 3 that don't work are installed the wrong way or there is a problem with the transistors for them.. check your soldering also?
