Hi,

I had  some special lines on my Bv3, and finally they changed the chassis.

Now, after repair,  i have a very good picture, but there is still a line on the top of the screen, when in Format 2 or 3.

It's not very annoying, but it's surely not normal.

What do you think about ?

 Thanks

You could adjust the Vam(plitude) and/or Vsh(ift) in the service menu.

Write down the original figures and change them slightly.

Make sure that you've set the BV3 in the correct format 2 or 3. Every format has its own settings.

Every chassis has its own settings according to the used tube. Changing the tube or chassis leaves you with a not optimal setup.

But make sure that it isn't the source which causes this.
