From the project
Loewe TV Q2500 Chassis VGA Module
Project based on work done by Oelii from circuit-board.de/forum
Schematic recreated from the scratch in KiCad. PCB based on Oelii's layout and verified with Desing/Electrical Rules Checker tools. Components footprints replaced with KiCad standard ones.
Original schematic from Loewe Q2500-M chassis service manual
L816 and L826 SMD 1210(3225) inductors value are unknown; 4.7uH in Q2300 VGA module schematic; can be replaced with 0R resistor.
