Sony KV-1746R

[Popester]

Not that I need another project but here goes. Was at the Early television convention and picked up a nice Sony. Has raster and sound. Retrace lines with no response from brightness control or G2 screen control. Yeah, I need a schematic but don’t have one and I’m just looking for a starting point. Convergence, color, and tint, all working good. Just need to drop the drive down. Don’t have a test adapter to test the jug, and was wondering if that’s my issue. I don’t think so, but looking for ideas. I couldn’t get iPhone to take a decent picture with the set on.any ideas?
