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 | ||
