There may be more than one independent issue; the lack of response *may* not be related to to the five not lighting up.
The first step is to check the 5 LEDs that are not lighting up to see what the issue is. Check to see, for example, if any of the LEDs is backwards by looking for the flat sides of the collars. Check to see if any of those LEDs is not properly soldered. If that all looks fine, then one of the LEDs may have been damaged. Use a fresh LED, and place its two pins across the pins of each of those 5 LED locations, to see if it will light up a little bit.
Please let me know what you find, and I’ll try to help you out from there. :)
