Unit has good vieo and audio from A/V inputs but no video from tuner. Traced to IC271. Have OSD when tuner is selected. Original problem was no power, found a bad diode and IC500(vertical). Replaced and now having this tuner problem. I'll check the menu again to see if I'm missing something. Any help appreciated.
