| Hitachi | C2558TN G8Q | This set would not switch automatically into A/V mode when a video or any other equipment was connected via the scart | The set could manually be placed into A/V from the tv's front end controls. The cure was to replace ZD301 ZTE251. I assumed it was a 2V but as i had none in stock i tried a 2.7V zener which worked perfectly. It's located near the scart socket | ||
