19" k7000 just recapped and installed a new flyback. Hoping powering on, i get rhse flickers/pops. Anode connection is clean and secure. Could it be a faulty so ket on the neckboard?
Following up on this - I swapped the neck board with another and the issue went away. I reflowed all solder on the neck board, paying special attention to the socket - re-installed, and all is well so just some bad solder joints fortunately.
