jmraider Posted October 25, 2018 Share Posted October 25, 2018 I have a controller with two 50 strand cosmic color bulbs. I have been able to narrow it down to one strand of 50 cosmic color bulbs not working properly. The first 9 bulbs in that strand work, but the rest do not. Is there anything I can do to fix this strand or should I just order a new strand? Link to comment Share on other sites More sharing options...
TheDucks Posted October 25, 2018 Share Posted October 25, 2018 First Question: Are they still under warranty? File a trouble ticket. You have a bad pixel (chip) or a damaged wire between the last good and the next. Do you have the proper voltage at the end of the string (Pwr to Gnd) Yes, then the issue may be the chip . Could be the last ON fails to pass the bucket of bits to the next, or the first Out chip is dead or data line is broken. . You could cut out the first OUT pixel, then splice the leads. If that does not work, then cut the last ON pixel and re-splice. Be sure to test the end of string voltage before cutting. at worst, you have a string of 48 Link to comment Share on other sites More sharing options...
jwblazek Posted October 25, 2018 Share Posted October 25, 2018 Seems I lose several every year. Finally took the string with the most bad lights and am cutting it apart for replacement bulbs to be spliced in as required. My CCB's are rigidly mounted, using the Boscoyo mounting strips, so no stress on the wires. These strips are then ty-wrapped to rigid 20' lengths of conduit. , so believe it is a design or quality issue within the bulb assembly itself Link to comment Share on other sites More sharing options...
