The CRT's (picture tubes) are bad in these sets, Sony has a technical buletin out on it. Adjusting the G2 (screen) controls will only prolong the inevitible, necessary replacement of the CRT's, Sorry for the news, this is a costly procedure and now new CRT's are not available for all models and will have to be replaced with a remanufactured unit. Best bet to adjust G2 down untill need replacement of whole TV. I have worked on quite a few of these, but the G2 will work for a while.
