I have a Sony 6' Projection I bought brand new 25 years ago it worked great but when it stoped dead I took it to be repaired and was told it needed a power transformer board ( not true I discoverd) after it's return it was never as sharp as before ! I'm sure he screwed something up somehow.
It does get a little better after an hour or so but not as great as it was.
Does anybody have copies of the service manual so I can tell what does what under the hood ?

Thanks for any help with this.....

On those old models you have to adjust the focus block and the G2 after the transformer is replaced

The tech was just lazy
