Yes, Mark. If it comes to that, I will troubleshoot and repair the module myself. I think the Flyback is good on this one. I'm going to try the Focus block first. (Maybe even the cheapo one, cause my estimate must stop at $321, and Zenith wants $133 for a Focus block ( I'm not set up with them for the $105 price) ,...H.B. wants only $75 for the Generic ). But,..Zenith pays the shipping, and H.B. will charge a COD charge, so I'm back up to $90 for the Generic with them. So,....???? ;-)
