Question about Zenith A50M91W 50" Rear Projection Television
Hi, this is a convergence chip failure and it can only be corrected by replacing the entire convergence board in this unit. This Board regulates and collaborates the RGB streams. if there is an apparent malfunction, it will become impossible to correct the issues you are experiencing at this time.
Simply replacing the convergence board or chip set will fix this issue.
