The situation is something like the following: https://www.reddit.com/.../white_beam_after_turning.../...
(I did not upload the original picture of my monitor because it might cause burn marks on the phosphor if I try to recreate the same for illustration)
I have attached the suspected section of the circuit diagram going to G1. I might be wrong, though.

Did anyone face the above issue? If so, is it the cap C505? or something else? (D504 seems right using a multimeter. Also, the R514 looks okay [it measures around ~30K on the multimeter, but my multimeter (analog) might not be that perfect])
