So anyway, back to my dim picture poor focus issue with my KV-1710 Trinitron.. I disconnected the K and G1 wires from all 3 colour guns on the CRT board. With the power on, I charged a 100uf @ 250v cap to 200 volts. I discharged it across the G1, and K of the guns 3 times on each gun . After this process, the picture was much brighter, and the focus is near perfect... Not sure how long it will last, but it looks great for now!!!
