|

Hi
I have problems geting the red tube focus on both sides of screen. I can get it on the sides but then it´s not focused in center. Green and blue is ok.
I have trayed mooving the focus coil and I can have focus egither in center or sides.. If I then adjust with electronic focus I can shift between center or side focus but they are never focused at the same time.
If I go to service menu and adjust focus on red there it hardly happens anything on sides even if I go from 0 -100. Just blury.
Needs some help

Try swapping the R and G focus leads. Chances are the focus board is bad. See if the green then does that. I've got spares..

Swaped red and green and the problem went over to green.
I´m getting a new board from the guy i bought it from (Jari in Gothenburg).
Thank you for a quick reply.
Best regards Per
