Title
Repairing LED Christmas Lights LEDs
Introduction
Although these lights have a three-year guarantee, it's cheaper to fix them yourself than to pay the postage to send the lights back. I bought T1 3/4 (5 mm) LEDs from Digikey, looking for anything in the 800 mcd or up range in the proper colors. I ended up buying:
404-1096-ND (red)
404-1097-ND (orange)
C503B-BCS-CV0Z0461-ND (blue)
C503B-GCN-CY0C0791-ND (green)
404-1092-ND (yellow)
The LEDS are in series in groups- three groups to a strand. If one LED in the group has failed, none in that group will light. The trick it to find out which one (or ones) is bad.
Its easiest if you have one working strand or part of a strand. If so, remove one LED from the good strand, and use that socket to test each LED, one at a time, from the bad strand. If the LED doesn't work in the good strand, replace the LED according to the directions that follow. There may be more than one bad one, so after replacing,if the bad stand still doesn't light up, go on to the next LED.
If you don't have a good strand to test with, and don't have another way to test the LEDs, then remove each LED, one at a time from the bad strand, and check the leads to make sure they're not broken. If broken, replace, if not, put the LED back and go on to the next one.
