Need help on K7400 - Lightbulb test works; still clicks. No B+
Recently got a capcom big blue with a k7400 (sticker reads 2574 or something similar i think) in it.
When I first tried it, got a chirping/clicking noise. Flyback did not show any visual signs (cracking/leak).
I checked the HOT, which read shorted out of circuit. Replaced the HOT, flyback, and did a cap kit. Also checked ZD701 (per the bulletin on this model) - it does not check shorted.
Still getting a chirping/clicking noise.
So I try the "lightbulb test" - lights up steady and stays on.
I tried reading TP202/3 - gets something like ~2.3v or something like that.
I'm kinda clueless at this point - any pointers?
