I'm really not happy with the way the blue is showing on the screen at the moment.

I have a couple more STK392-040's here. Could it improve it if I change the blue one over perhaps?

Answer to that is Nope.

Changed the IC over and is still the same. Blue is blurry and doesnt seemed to be repairable with the Focus/Saturation/Lens dials. Sad

It probably is, but it eliminates the Perfect focus, and is still very slightly off (noticabley).

Red and Green I've messed a little with and they are spot on, blue wont follow suit for some reason. It seems wider or bulkier.

I'll try to get a picture to show you how I mean.

Anything else I should check? Perhaps another resister somewhere?

Swap leads on the screen/focus block. In other words follow the blue screen/focus wires and swap them with the red or green screen/focus wire and put the red or green wires where the blue came from. I'v had bad focus/screen blocks before.

I'll give it a go (when I work out what and where these leads are) Smile
