ftrevor Posted February 13 Share Posted February 13 hey there, I have a CTB16PC v1 that has been running for years. This last season (of course mid December after the show was runing for 2 weeks ) channels 1-8 stopped working. I have performed the following without resolving the issue. Check fuses - both fuses are good and there is 115v post fuse for both side. Check soldering and looked for any visible shorts or damege Replaced 74AC273 at U4 Does anyone have any other suggestion to debug or repair? Thanks Ftrevor Link to comment Share on other sites More sharing options...
