I was going though something new to me the Barco Quick reference guide.
Could someone give me some pointers. I have read its 17v for 808 and 17.5v for a 1209?
i am trying to go step by step. If someone going help me on the first three.
(1) Check the 17 volt rail with a meter. Adjust if needed (see service manual). Make sure that you use a video line frequency 15.6/15.7 or an internal pattern, also your H-width setting must be at 49 when you do this.
(1a) Check the 48V pot on the SMPS (see service manual).
(1b) Check the horizontal linearity pot on the horizontal deflection board (see service manual).
