NT-2701 Ticking Sound

[powerplay]

I have a Neotec NT-2701 with a ticking problem. Now the high output has been checked and it's good, I also replaced it for the heck of it and no luck. Various Items have been replaced which I will be listing below.

- A complete cap kit
- What I call the Chicklet cap kit (C423,C419,C421, C450)
- Flyback T402
- Also replace the control brd with a working one(we had one situation which cause a monitor to tick, so we decided to try it)
- Q402
The monitor board is still ticking and Q402 is not blown .  I don't know what else to change , about 98% of the time these items do the trick. Any help would be appreciate it. Thanks guys

Is the ticking on the board or near the HV-cup.

hmmm,neotec my favourite
there is a high voltage polypropylene cap on the collector of the HOT,make sure is good with a capacitance meter-although you can normally see if they go because you get a crack on the body
